PROCESS FOR THE PREPARATION OF 2-ALKYL-4-ACYL-6-TERT- BUTYLPHENOL COMPOUNDS

摘要

The subject invention relates to a process for the preparation of 2-alkyl-4-acyl-6-tert-butylphenol compound having chemical structure (1), wherein -R is an aliphatic group having a terminally unsaturated moiety selected from -C~CH and -CH=C=CH2, and R' is selected from saturated straight, branched or cyclic alkyl having from 1 to about 10 carbon atoms; the 2-alkyl-4-acyl-6-tert-butylphenol compound being produced in a reaction mixture comprising the corresponding 2-alkyl-6-tert-butylphenol (2), the corresponding carboxylic acid: RCOOH, and trifluoroacetic anhydride.
