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.

[application 1] it is used as solvent and organic synthesis [application 2] it is a non combustible low boiling solvent. It is used for cellulose acetate film-forming, aerosol, antibiotic and vitamin production. It is also used as extractant and metal cleaning agent [application 3] dichloromethane is the raw material for the production of fungicides myclobutanil and miconazole, and it is also a good solvent. Application 4: extraction solvent. For example, it is used to extract caffeine from coffee beans. It can also be used as extraction solvent for hops, spices and oleoresin. Pigment diluent. [application 5] in addition to organic synthesis, the product is also widely used as cellulose acetate film-forming agent, cellulose triacetate drawing agent, petroleum dewaxing agent, aerosol and solvent in the production of antibiotics, vitamins and steroids, as well as cleaning and degreasing agent for metal surface coatings. In addition, it is also used for grain fumigation and refrigeration of low-pressure refrigerator and air-conditioning device. It is used as auxiliary foaming agent in the production of polyether urethane foam and as a foaming agent for extruding polysulfone foam plastics.
