P-TOLUIC ANHYDRIDE - Introduction
4-methyl benzoic anhydride, also known as p-methyl benzoic anhydride, is an organic compound with a chemical formula of C9H10O2.
Nature:
4-methyl benzoic anhydride is a colorless to slightly yellow crystal or powder substance with a special fragrance. It is soluble in organic solvents such as ethers, alcohols and ketones, and insoluble in water. It has good stability, but it will undergo hydrolysis under strong alkaline conditions.
Use:
4-methyl benzoic anhydride is widely used in the fields of medicine, pesticide, perfume and dye. It is an important raw material for the synthesis of a variety of pharmaceutical intermediates. In addition, 4-methylbenzoic anhydride can be used as a raw material for dyes and has good dyeing properties. It is also a common fragrance ingredient and is often used in fragrances and perfumes.
Preparation Method:
4-methylbenzoic anhydride can be prepared by esterification of benzoic acid and formic anhydride. In the reaction, benzoic acid is reacted with formic anhydride in the presence of a suitable catalyst and solvent under mild conditions to form the desired product. The method is simple and the yield is high.
Safety Information:
4-Methylbenzoic anhydride is an organic compound that is irritating. Avoid direct contact with skin and eyes, and avoid inhaling dust or gas. Maintain a well-ventilated environment during use and storage, and take appropriate personal protective measures, such as wearing protective gloves and goggles. In case of accidental contact or inhalation, wash the affected area immediately and seek medical help.
