Phthalic anhydride is the organic compound with the formula C6H4 (CO)2O. It is the anhydride of phthalic acid. This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins. Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes. Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. Other reactions with phthalic anhydride yield phenolphthalein, benzoic acid, phthalylsulfathiazole (an intestinal antimicrobial agent), and orthophthalic acid.

Phthalic anhydride is used in the manufacture of unsaturated polyesters and as a curing agent for epoxy resins. When used as a pigment, it can be responsible for sensitization in ceramic workers.n

Polyether Polyol also known as Polypropylene glycol is used as an antifoaming agent and as a humectant in cosmetics and foods. It is used as a solvent in flavoring and coloring or agents and pharmaceutical products. It is the main component in automobile antifreeze and engine-cooling liquids and brake and hydraulic fluids. It is used to prepare polyurethane elastomers. It is used as a soft segment to make self-healing polymeric networks.

Acetonitrile is an organic compound with the molecular formula CH3CN or c2h3n. It is a colorless liquid, highly volatile, with a special smell similar to ether, excellent solvent performance, and can dissolve a variety of organic, inorganic and gaseous substances. It has certain toxicity and is infinitely miscible with water and alcohol. Acetonitrile is an important organic intermediate, which can undergo typical nitrile reactions and is used to prepare many typical nitrogen-containing compounds. Acetonitrile can be used as a solvent for the synthesis of vitamin A, cortisone, carboamine drugs and their intermediates, and also as an active medium solvent for the manufacture of vitamin B1 and amino acids. It can replace chlorinated solvent. It is used in vinyl coating, fatty acid extractant, alcohol denaturant, butadiene extractant and solvent of acrylonitrile synthetic fiber. It is also used in fabric dyeing, lighting, perfume manufacturing and photosensitive material manufacturing.

Chemical analysis and instrumental analysis

Acetonitrile is an organic modifier and solvent used in thin layer chromatography, paper chromatography, spectroscopy and polarographic analysis in recent years. Since high-purity acetonitrile does not absorb ultraviolet light at 200nm ~ 400nm, an application being developed is as a solvent for high-performance liquid chromatography HPLC, which can make the analytical sensitivity as high as 10-9 levels.

Intermediate of synthetic medicine and pesticide

Acetonitrile can be used as an intermediate in the synthesis of various medicines and pesticides. In medicine, it is used to synthesize a series of important pharmaceutical intermediates, such as vitamin B1, metronidazole, ethambutol, aminopteridine, adenine and antitussive; In pesticides, it is used to synthesize pyrethroid insecticides, acetaminophen and other pesticide intermediates.

Semiconductor cleaning agent

Acetonitrile is an organic solvent with strong polarity. It has good solubility in grease, inorganic salt, organic matter and polymer compounds. It can clean grease, wax, fingerprints, corrosive agent and flux residues on silicon wafers. Therefore, high purity acetonitrile can be used as semiconductor cleaner.

Application

Propionic acid is an important chemical raw material. Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices.

The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst.

Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.
