p-Hydroxybenzoic acid was esterified with corresponding alcohols in benzene, using conc. sulfuric acid as the dehydration agent, and amyl, hexyl, heptyl, and octyl esters were prepared. Iodination, bromination, and chlorination of p-hydroxybenzoic acid afforded 3-iodo-, 3-bromo-, and 3-chloro-4-hydroxybenzoic acids and their esterification afforded a total of 24 kinds of methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl, and octyl esters of these 3-halo-4-hydroxybenzoic acids.
