The Production Process Optimization of Sodium Methylate with Sodium Hydroxide and Methanol

The current preparations of sodium methylate are mainly two methods of sodium and sodium hydroxides.

At present, there are mainly two production methods: metal sodium method and alkali method. Sodium metal method refers to solid bulk or molten metal sodium reacts directly with lower alcohols to produce sodium alcohol and hydrogen

The advantages of sodium methoxide are high purity, simple process, low equipment cost and unsafe, the generated hydrogen is very easy to explode, and the raw metal sodium is very active and expensive.

Sodium Methoxide 30% Solution in Methanol, CAS No.124-41-4

Alkali Method

It refers to the reaction of methanol and sodium hydroxide to produce sodium methoxide and water. The advantage of this method is that the raw material is convenient

The utility model has the advantages of easy availability, low cost and safe operation. Its reaction is reversible, but it is very easy to cause reverse reaction

It should not be complete. There are often impurities such as sodium hydroxide in the product, so it is not necessary for alkali production

Remove the water and add catalyst to make the reaction move towards the product as far as possible.

Distillation and other separation operations shall be carried out to reduce impurities as much as possible.

Sodium process is simple, high conversion rate, but too dangerous. Alkaline process is low conversion rate because of its strong reversibility while needed to continuously remove the water of reaction, but it is low cost. The actual production is produced by reactive distillation apparatus. The major influence factors of the reaction are reaction temperature, mass ratio of methanol and sodium hydroxide, and reaction time. Using single -factor experiment method, the law of reaction with the changes of the influence factors was studied. Experimental results showed that the higher the mass fraction of sodium methylate was obtained, the higher temperature increases, the greater the mass ratio of methanol and sodium hydroxide , the longer the reaction time. The optimal reaction conditions were determined.

Liquid sodium methoxide
Sodium methoxide, a dangerous chemical, is corrosive and self ignitable. It is mainly used in pharmaceutical industry and organic synthesis as condensing agent, chemical reagent, catalyst for edible oil treatment, etc. Sodium methoxide is widely used in the production of sulfonamides. Sodium methoxide is also a catalyst for organic synthesis, which is used in pesticide production and oil processing industry.

Liquid sodium methoxide is widely used in the production of sulfonamides. Sodium methoxide is also a metal catalyst for organic synthesis, which is used in the production and processing of chemical fertilizer and vegetable oil.
There are two ways of sodium methoxide commodity in industrial production: solid and liquid. The solid is pure sodium methoxide and the liquid is methanol solution of sodium methoxide. The content of sodium methoxide is 27.5 ~ 31%.
Because sodium methoxide is a risk chemical, it is inseparable and closed when packaging. Be sure to ensure safety.
General plastics, such as PP, ABS and PC, are etched by ethanol. Only plastics such as PTFE can, but the price is very expensive. Metal drums are proposed.

On February 21, China Nitrogen Fertilizer Industry Association held the 2022 China methanol industry conference in Hangzhou to summarize the work of methanol industry in 2021 and analyze and discuss the methanol market and development trend in 2022. On the same day, China nitrogen fertilizer industry association commended the top 20 national methanol production enterprises in 2021 and advanced energy-saving enterprises in the methanol industry.
Gu zongqin, President of China nitrogenous fertilizer industry association, pointed out at the meeting that at present, the development of methanol is facing positive factors such as the recovery of the world economy, the steady rise of international oil prices, the continuous increase of downstream product consumption and the easing of overcapacity. However, we should also see the adverse factors and still face many challenges.
Gu zongqin believes that with the economic recovery of various countries, the demand for chemical products will inevitably increase, which will further drive the recovery of methanol prices. At the same time, the recovery of international oil prices will drive the rise of foreign methanol prices, help to improve the competitiveness of domestic coal based methanol production, and will also strongly support domestic prices.

The consumption data in recent ten years show that the growth of methanol consumption in China is roughly more than 10% every year. Gu zongqin predicted that the growth of methanol consumption in the next few years will also maintain the previous trend for three reasons: first, the pilot work of methanol vehicles will continue; Secondly, alcohol based fuels for boilers and stoves as clean substitutes for coal can greatly improve air quality; Third, the consumption of methanol downstream products will continue to grow, and coal to olefin is still the main direction of the development of the industry. In addition, new downstream products are still being researched and developed, such as toluene methanol methylation to produce p-xylene.
However, China’s methanol industry still faces a series of challenges. Gu zongqin said that the task of removing production capacity this year is still arduous, the development of upstream and downstream is still unbalanced, the pressure on safety and environmental protection continues to escalate, and the price of raw materials is facing rising pressure.
Although the methanol units that have stopped production for two consecutive years are more than 9 million tons / year, involving more than 120 production enterprises. However, Gu zongqin pointed out that with the improvement of the market, some old production capacity with high energy consumption, high emission and backward devices may be driven. In addition, a large number of new units are still put into operation and technological transformation and capacity expansion every year, resulting in a high rate of increase in methanol production capacity, and the task of eliminating backward production capacity is very arduous.
The pressure of safety and environmental protection in methanol industry will continue to escalate. Gu zongqin said that as a chemical enterprise with high energy consumption and high emission, methanol enterprises are facing great pressure from many aspects, such as the significant rise of environmental protection treatment costs and power costs, as well as the shutdown and production restriction according to the emission reduction requirements during the emergency response period.
In order to realize the high-quality development of methanol industry, Gu zongqin proposed to do a good job in five aspects this year: continue to do a good job in reducing production capacity; Accelerate the adjustment of product structure, expand the industrial chain, and improve product added value and market competitiveness; Accelerate the popularization and application of advanced technology and promote the technological progress of the industry; Further improve the level of energy conservation and emission reduction in the industry; Actively carry out international exchanges and cooperation.
Junyuan Petroleum Group has made remarkable achievements in tapping energy-saving potential, deepening energy conservation and emission reduction and improving energy utilization, Won the title of “advanced enterprise in energy conservation in methanol industry in 2021”.

Pentane is a flammable blowing agent that offgases from product, yet EPA document 540/3-90-020 states that 85% of the pentane is emitted within 48 hours of the start of the expansion process in the factory, with the remainder emitted over time. Considering manufacturer’s curing process, the vast majority of the 15% remainder of the pentane should be emitted prior to shipment, with the remainder being emitted during subsequent shipment, storage, and usage. Cyclopentane is a liquid below 120°F and isopentane liquefies at 82°F; n-pentane remains in a gaseous state above 97°F.

Volatile Organic Compounds (VOC):
Pentane: EPS manufacturing uses beads as a raw material, and EPS beads typically contain 4%-7% pentane by weight, which is defined as a VOC by the EPA. EPA document 540/3-90-020 states that 85% of the pentane contained in the EPS bead is emitted within 48 hours starting with the expansion process (which occurs within the manufacturing facility). The remaining pentane is released over time, there is likely negligible pentane content in the foam by the time of installation.
Styrene: Styrene is considered a VOC by the EPA. While Certificates of Analysis from bead suppliers typically do not state a styrene monomer content of EPS bead, several EPS bead suppliers have established that EPS beads typically contain styrene monomer, 900 to 1000 ppm by weight. After pre-expansion and expansion of beads, concentration should be considerably reduced.

What is Expanded Polystyrene (EPS)?
Expanded PolyStyrene (EPS) is a white foam plastic material produced from solid beads of polystyrene. It is primarily used for packaging, insulation, etc. It is a closed-cell, rigid foam material produced from:
Styrene – which forms the cellular structure
Pentane – which is used as a blowing agent
Polystyrene is produced from crude oil refinery product styrene. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. Polystyrene granulate is prefoamed at temperatures above 90°C. Both styrene and pentane are hydrocarbon compounds and are obtained from petroleum and natural gas byproducts.
EPS is very lightweight with very low thermal conductivity, low moisture absorption and excellent cushioning properties. One of the serious limitations of polystyrene foam is its rather low maximum operating temperature ~80°C. Its physical properties do not change within its service temperature range (i.e. up to 167°F/75°C) for long-term temperature exposure.
Its chemical resistance is nearly equivalent to the material upon which it is based – polystyrene.
EPS is 98% air and it is recyclable.

What is the chemical name of Pentane?
General pentane (hereafter, pentane) is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-Pentane (the most important isomer), isopentane, and neopentane. n-Pentane is a constituent of crude oil and a component of the condensate from natural gas production.

Is pentane a blowing agent?
Blowing agent Pentane is a hydrocarbon solvent coming directly from the natural gas and crude oil. Pentane as blowing agent in (PUR) insulation foam : N-Pentane (CAS : 78-78-4).

What is the average cost of foam insulation?
The national average cost to fully insulate a home with spray foam is $10,000 to $30,000. Most homeowners spend around $20,000 on a mixture of open and closed cell insulation 6 inches thick in an existing 2,000 sq.ft. home. This project’s low cost is around $6,000 for 4 inches of open cell foam covering the attic floor.
