use
solvent. Used as a polymer inhibitor for vinyl plastic monomers, UV inhibitors, dye intermediates and the antioxidant BHA (3-Tbbyl-4-hydroxyphenyl ether) used to synthesize edible oils and cosmetics. Its greatest advantage is that the addition of MEHQ monomer and other monomers do not have to be removed when co-polymer, can be three direct co-polymer, but also can be used as anti-aging agents, antioxidants and so on.
Production method
4-methylphenol can be produced by using parathylate as raw material for phenylphols, or methanol as methylation agent at high temperature and high pressure and catalytic. Another newer method is to react with parabens with methanol in the presence of benzodiazepine. Mix methanol and concentrated sulphuric acid evenly, add phenol, heat backflow, drop and react 3h to the methanol solution of benzene. Cooling, neutralizing with 40% sodium hydroxide solution, filters out sodium sulfate precipitation. After recovering methanol, the filter is extracted with ether, the extract is steamed away ether, then decompression distillation is carried out, and the finished product is collected at 110-112 degrees C (0.53 kPa) fractions. The yield was 76 per cent.
