Organic Solvent

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.

Tert-butanol is a kind of colorless oily liquid with strong alcohol smell, which is mainly used as organic solvent, chemical raw materials for the preparation of drugs and spices. In the field of agriculture, tert-butanol is an important intermediate of buprofezin, fenozide, tebufenozide, pyridaben and buprofezin. In the field of chemical industry, tert-butanol is often used as fuel additive for internal combustion engine (preventing carburetor from freezing) and antiknock agent. It can also be used as intermediate of organic synthesis and alkylation raw material for producing tert butyl compounds, and can produce methyl methacrylate, tert butyl phenol, tert butylamine, etc.

Methanesulfonic acid is a kind of caustic chemical, which has a wide application prospect in electroplating field. It has been proved to be a good substitute for fluoroboric acid or phenol sulfonic acid. Methanesulfonate electroplating solution has been applied to tin and tin lead alloy electroplating, and the product features are as follows: 1. Bright pure tin electroplating of methanesulfonate type, with fine crystal, uniform coating, bright silver white, good solderability, is suitable for electronic industry. 2. The bath has high plating speed, wide current density range, fast deposition speed and excellent deep plating ability. 3. Good weldability can be maintained after standard aging test or long-term storage. 4. No fluorine boric acid, easy to treat waste water, low corrosiveness, conducive to environmental protection.

Trichloroethylene is a common solvent in industry. It is colorless, toxic, transparent, easy to flow, not burning, volatile, aromatic liquid, has anesthetic effect on nerves. Pure trichloroethylene decomposes slowly. When the mixture of trichloroethylene and oxygen is irradiated by ultraviolet, the decomposition of trichloroethylene is accelerated. Trichloroethylene is mainly used for metal degreasing and dry cleaning of wool and fabrics. Solvent for resin, asphalt, coal tar, cellulose acetate, nitrocellulose, rubber and coatings. It is used as anaesthetic in medicine and raw material for synthesis of monochloroacetic acid in pesticide.
