Abstract
C3-C6 alkylphenols of 47 kinds were synthesized. Polymethylphe-nols were synthesized by transferring methyl groups from tetramethylbenzene to coexisting dimethylor trimethylphenols on asilicaalumina or a zeolite catalyst. Diethylphenols were synthesized transferring ethyl groups from diethylbenzene to coexisting ethylphenols on a silicaalumina catalyst. Other phenols were synthesized by allowing the phenols to react with alkyl bromide on aluminium chloride. The position of the alkyl group was determined by superposition of the reaction pathways. The 47 synthesized phenols and 26 commercial phenols were analyzed by GC-FID and GC-MS and their retention indices were calculated.
