Organic Chemical Materials

Pyrrolidin-2-one is the simplest member of the class of pyrrolidin-2-ones, consisting of pyrrolidine in which the hydrogens at position 2 are replaced by an oxo group. The lactam arising by the formal intramolecular condensation of the amino and carboxy groups of gamma-aminobutyric acid (GABA). It has a role as a polar solvent and a metabolite.This product is mainly used as solvent and organic synthesis intermediate. It can be used to manufacture nylon-4 and vinyl pyrrolidone.

N,N'-Diisopropylcarbodiimide is mainly used in the dehydration of amikacin and glutathione. It can also be used in the synthesis of anhydrides, aldehydes, ketones and isocyanates. When N,N'-Diisopropylcarbodiimide is used as dehydration condensing agent, it can be formed by short time reaction at room temperature, and the product is diisopropylurea. It can also be used in the synthesis of peptide and nucleic acid. It can be easily synthesized from compounds with free carboxyl group and free amino group at room temperature. N,N'-Diisopropylcarbodiimide is widely used in medicine, health care products, cosmetics, biological agents and other organic synthesis fields.

Acetonitrile is the simplest organic nitrile. It is colorless and transparent liquid at room temperature. It is very volatile. It has a special odor similar to ether. It is flammable and has a bright flame when burning. It is miscible with water, methanol, carbon tetrachloride, methyl acetate, ethyl acetate, dichloroethane and many unsaturated hydrocarbon solvents. It is toxic and can be metabolized into hydrogen cyanide and thiocyanate. Acetonitrile is an important organic intermediate with excellent solvent properties. It is widely used as polar aprotic solvent. The most important use of acetonitrile is as a solvent. It can be used as a solvent for the synthesis of vitamin A, cortisone, carboamine drugs and their intermediates. It can also be used as an active medium solvent for the manufacture of vitamin B1 and amino acids, and can replace chlorination solvent. Acetonitrile can also be used as extractant of fatty acid, alcohol denaturant, butadiene extractant and solvent of acrylonitrile synthetic fiber. It also has many uses in fabric dyeing, lighting industry, perfume manufacturing and photosensitive material manufacturing.

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. The product has high octane number and can be used as automobile and aircraft fuel.

It can be used in paints and other coatings. It's also used for glue and as a cleaner.
