Isopentane Product Features

by David Zhang, Sales Manager at Junyuan Petroleum Group June 7, 2017

Isopentane (isopentane, 2-methylbutane), also known as 2-methylbutane, with chemical formula C5H12, is a colorless, transparent and volatile liquid with pleasant aromatic smell. It is mainly used in organic synthesis and also as solvent.

Product Uses
It can be used as solvent for catalyst in polyethylene production, foaming agent for expandable polystyrene, foaming agent for polyurethane foam system, deasphalting solvent and so on.
When used as solvent, it has the same effect as pentane, hexane and heptane, and its solubility is slightly worse than pentane. The product has high octane number and can be used as automobile and aircraft fuel.

Pentane Foaming Agent

by David Zhang, Sales Manager at Junyuan Petroleum Group June 7, 2017

Pentane foaming agent is extremely flammable. Its vapor and air can form an explosive mixture. It is very easy to burn and explode in case of open fire and high heat Strong reaction with oxidant and even combustion Liquid is lighter than water and insoluble in water. It can drift and spread to a distance with water and cause combustion in case of open fire In the fire scene, heated containers are in danger of explosion.

The new technology of hydrobenzene removal with pentane foaming agent is to remove impurity benzene from raw materials under mild conditions (temperature 130 ~ 150 ℃, pressure 0.3 ~ 0.5MPa) and nickel catalyst. This process is used in the production of blowing agent of Junyuan Petroleum Group. After the application of this technology, the benzene content in pentane blowing agent is reduced from 300mg / kg to 5mg / kg, which has good economic and social benefits.

Satisfied with the dealer and the customer.

n-Hexane
Package kg: 132 / barrel quality index (national standard): 98%, 80%
N-hexane is an organic compound with molecular formula c6h14. It is a straight chain saturated fatty hydrocarbon. It is a colorless liquid with weak special smell obtained from crude oil cracking and fractionation.
It is volatile, almost insoluble in water and easily soluble in chloroform, ether and ethanol. It is mainly used as solvent, such as vegetable oil extraction solvent, propylene polymerization solvent, rubber and coating solvent and pigment diluent.
It is used for extracting various edible oils and fats in soybeans, rice bran, cottonseed and spices. In addition, n-hexane isomerization is one of the important processes for producing blending components of high octane gasoline.

Octanes

Physical Data and Uses of n-Octane

by David Zhang, Sales Manager at Junyuan Petroleum Group June 7, 2017

Preparation Method:
Add 100g (1.53mol) of zinc amalgam, 250ml of concentrated hydrochloric acid and 50ml of water into the reaction bottle equipped with stirrer, reflux condenser and vent pipe (extending into the bottom of the bottle), add 40g (0.35mol) of octanone-2 (2) under stirring, and slowly inject hydrogen chloride gas. If the reaction is too violent, the hydrogen chloride gas can be suspended. After 2-3H, most of the zinc amalgam reaction was completed, hydrogen chloride was stopped and placed overnight. Remove the agitator and change to steam distillation unit for steam distillation until the distillate is transparent. The upper oil layer was separated, washed twice with distilled water, fractionated after drying with anhydrous sodium sulfate, and the fraction at 124-126 ℃ was collected to obtain 26G octane (1) with a yield of 58%.

Pentane Blends

Pentane Used as Foaming Agent

by David Zhang, Sales Manager at Junyuan Petroleum Group June 7, 2017

Pentane as foaming agent is mainly used to foam polyurethane and styrene. In pentane foaming agent, pentane is mainly n-pentane and isopentane, and when the proportion reaches more than 99%, it can be used as styrene foaming agent, and the finished product is EPS.

In addition, n-pentane can be used for foaming of building plates. The main purpose of making polyurethane foaming agent is cyclopentane, which is mainly used for foam in the refrigerator door. When you go home, you can see the label of cyclopentane on your refrigerator. This is mainly due to the cavitation of ozone layer before foaming, but later replaced by 141b, but it is still polluted. Pentane will not be cleaned. Pentane has a low density of about 0.62, which is flammable and volatile. As a foaming agent, it uses its volatile characteristics to leave small holes in styrene or polyurethane. It should belong to physical foaming without chemical reaction. Up to now, EPS foaming with pentane has been a mature system, while polyurethane foaming with cyclopentane is still developing. Because China pays close attention to industrial safety, few manufacturers can change the foaming agent from 141b to cyclopentane for polyurethane, mainly large refrigerator factories such as Haier and Hisense.
