• DESCRIPTION

Heptane is metabolized to its parent alcohols (mainly 2-heptanol and 3 heptanol, and to a minor extent 1-heptanol and 4- heptanol).The heptanol metabolites are conjugated by glucuronates or sulfates, and subsequently excreted in urine. Heptane is further metabolized at relatively high rates by hydroxylation before being converted to the corresponding keto forms.

Heptane (CAS# 142-82-5)

n-Heptane, also known as N-heptane or CH3-[CH2]5-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Straight-Chain AlkaneHeptane or n-heptane is the straight-chain alkane with the chemical formula H₃C(CH₂)₅CH₃ or C₇H₁₆, and is one of the main components of gasoline. Synonyms & Trade Names Heptane, normal-Heptane CAS No. 142-82-5 RTECS No. MI7700000. DOT ID & Guide. 1206 128. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale.

Junyuan Petroleum Group’s n-Heptane, 99%, CAS No. 142-82-5, medical grade of n-Heptane and its applications: It is widely used for the production of rubber and plastic,painting material, dyestuff, printing ink, adhesive, medicine, agricultural chemicals, food additives, feed additive, flavor spices, cosmetics.

Lab-grade chemicals, because of their low cost and good chemical purity, are used widely in educational applications, such as teaching laboratories at both the secondary school and college levels; however, lab-grade chemicals would not be appropriate for use in the quality control laboratory of a pharmaceutical or medical device.

Heptane is a flammable, volatile, organic, straight-chain alkane of seven carbon atoms. Available in a range of quantities, purities, and reagent grades, heptane is a commonly used non-polar solvent and a key component in gasoline. Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline dispensed globally. Any of several isomeric, volatile, colorless, highly flammable liquid hydrocarbons, C7H16, obtained in the fractional distillation of petroleum and used as solvents.

The straight-chain isomer is also used as a standard in determining octane ratings and as an anesthetic. Thermodynamic properties of standard n-heptane from 155 to 270K and of 2,2-dichloropropane from 135 to 270K, J. Chem. Thermodynam., 1972, 4, 773-782.

Acetone and n-Heptane are widely applied in pharmaceutical industry as benign solvents and are observed in the wastewater.Because acetone and n-hexane can form an azeotropic mixture, it is impossible to recover acetone and n-Heptane with high purity from the wastewater using conventional distillation.

High purity n-Heptane is produced from crude oil through precision refining and distillation that is used in the measurement of octane rating for fuels. It is also used for the purification of pharmaceutical products and other synthetic organics.

n-Heptane is widely applied in laboratories as a totally non-polar solvent. Usage Statement . Unless specified otherwise, MP Biomedical’s products are for research or further manufacturing use only, not for direct human use. For more information, please contact our customer service department.

It is written as n-Heptane when the polymer is unbranched, hence depicts a straight-chained structure. The presence of heptane in paintings and coatings forces the consumption of oxygen in microorganisms, which is a vital element in metal corrosion.

A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Major uses of solvents are in paints, paint removers, inks, dry cleaning. Specific uses for organic solvents are in dry cleaning, as paint thinners, as nail polish removers and glue solvents, in spot removers, in detergents and in perfumes. Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes.

Polyethylene (PE) is one of most widely used plastics in the world and has a huge spread over industries, segments and applications. PE enables food to be packed economically with a prolonged shelf life, chemicals to be safely transported and distributed, clean water to reach all parts of the population, new cars to be protected from scratches and a myriad of other useful applications used in our everyday lives.

Polyethylene (PE) is characterised by many families and product properties allowing a wide variety of end uses.

THE POLYETHYLENE PORTFOLIO STRETCHES FROM STANDARD GRADES TO SPECIALTIES AND FUNCTIONALISED PE.

LDPE (Low Density Polyethylene)produced by Tubular or Autoclave technologies is available with standard (0.918-0.925 g/cc)and medium densities (0.930-0.940 g/cc) together with very low gel levels. LDPE offers high output grades for all extrusion and injection technologies and is available with compliance to food and Pharma standards.

LLDPE (Linear Low Density Polyethylene) C8 Octene, C6 Hexene, and C4 Butene. LLDPE are available from higher densities (up to 0.941 g/cc) down to very low density PE (0.905 g/cc). LLDPE (Linear Low Density Polyethylene) is used in extrusion, blown film, roto- moulding, injection moulding for food-packaging, frozen-food, floor-heating-pipes, stretch-film, cosmetic and pharmaceutical tubes etc.

HDPE (High Density Polyethylene); bimodal and unimodal for blown film, blow moulding, Injection moulding or other extrusion processes. HDPE grades are available with UV-Stabilisation, and certification to meet UN standards for blow moulded chemical containers.

Plastomers for modification of PE or PP to increase properties like sealing, impact or softness. The Plastomers offer a wide range of grades, densities and comonomers ( Etylene- Octene or Butene based Polymer.

Functional Polymers such as EEA, EAA, MAH create adhesion to other polymers like EVOH or Polyamide barrier layers in extrusion process. These adhesives create a strong and reliable bond also to other substrates in co-extrusion processes. EAA can also be used in water based dispersions or hot melts (in addition to metallocene based polyolefin hot melt adhesive).

EVA for foam, extrusion or Hot Melt Adhesive applications.

Polyethylene might be divided into three groups:

• Standard Polyethylene
  • LDPE – Low Density Polyethylene
  • HDPE – High Density Polyethylene
  • MDPE – Medium Density Polyethylene

Pentane Uses

Pentane CAS Number: 109-66-0
Molecular formula: C5H12
IUPAC Name: pentane. 

1. It can be used as low boiling point solvent, foaming agent in plastic industry, and also used as fuel of automobile and airplane together with 2-methylbutane, making artificial ice, anesthetic, synthesizing pentanol, isopentane, etc.
2. Gas chromatographic analysis standard. It can be used as anesthetic, solvent, low temperature thermometer, artificial ice, pentanol, isopentane, etc.
3. Used to prepare standard gas, calibration gas and molecular sieve desorption agent.
4. Used as solvent, gas chromatography reference liquid and anesthetic. It is also used in organic synthesis and low temperature thermometer.
5. Used as solvent, making artificial ice, anesthetic, synthesizing pentanol, isopentane, etc.

Pentane raw materials are mainly from oil refineries. Pentane products are widely used as blowing agent, solvent and chemical raw materials. At present, there are 36 high-purity isopentane, n-pentane, cyclopentane and mixed pentane blowing agents in China, with a production capacity of about 150 kt / A. the annual consumption of pentane in China is nearly 66 KT, of which the annual consumption of pentane is about 66 KT, The consumption of PEPS pentane foaming agent accounts for 45% of the total consumption; the consumption of polyurethane foaming agent accounts for about 50% of the total consumption; the consumption of linear low-density polyethylene pentane carrier solvent accounts for about 5% of the total consumption. Domestic pentane supply exceeds the demand, but the supply of high-grade products is insufficient. Therefore, the newly-built unit during the 10th Five Year Plan period must adopt domestic advanced technology, Adopt cheaper feed gas to ensure product quality, reduce production cost as much as possible, strengthen market development and improve market competitiveness of products.
