Phenylacetic acid is an important intermediate in medicine, spices, pesticides and industrial synthesis. In terms of medicine, phenylacetic acid is mainly used in the production of penicillin, dimethazole, atropine and other drugs, and the demand for penicillin production is particularly huge; in terms of spices, phenylacetic acid is widely found in grapes, strawberries, cocoa, green tea, honey, etc. It has a sweet honey flavor at low concentrations, and is often used as a fixative or modifier in soaps, detergents, and cleaners; in terms of pesticides, phenylacetic acid itself is a pesticide plant growth hormone, which can be chlorinated and esterified to obtain α-chlorinated Ethyl phenylacetate is used in the production of Daofengsan and ethyl Daofengsan; in industry, phenylacetic acid is used in the preparation of fuels, liquid crystal materials, high-performance engineering plastic curing agents, fluorescent whitening agents, and the synthesis of β2 alkylpropionaldehyde catalyst, etc.
In recent years, with the rapid development of domestic penicillin G salt and its downstream products industry, the demand for phenylacetic acid has shown a rapid development trend.
Industrial salt is one of the most basic raw materials in the chemical industry. The main components are sodium chloride, sodium nitrite, etc. It is called "the mother of the chemical industry". Among the main products of the basic chemical industry, hydrochloric acid, caustic soda, soda ash, ammonium chloride, and chlorine gas are mainly produced from industrial salt. In addition, it is widely used in food, feed, leather, ceramics, glass, soap, dye, oil and other industries.
