Abstract
A synthetic method for acetoxybenzoic acid, which comprises of the following steps: (a) Phenol and metallic alkaline forms a phenolic salt; (b) After removing most of the water, the phenolic salt undergoes carbonylation reaction with carbon dioxide; (c) dissolves the reaction product and adjusts its pH value to weak alkalinity using acid; (d) at below 160 C undergoes acetylation reaction with acetyl acetate; (e) adjusts pH value to obtain acetylation product.
