摘要：2-Substituted-4,6-di-t-butylresorcinol represented by the general formula:##STR1## wherein R represents a straight or branched alkyl group having 1 to 20 carbonatoms, a straight or branched alkenyl group having 2 to 20 carbon atoms and at least onedouble bond, or an aralkyl group, but the tertiary carbon atom of R is free from directbonding to the benzene nucleus, is prepared by allowing 4,6-di-t- butylresorcinol toreact with a halogen compound represented by the general formula: ##EQU1## whereinR has the same meaning as defined above, and X represents a halogen atom, excludingthe X bonded to the tertiary carbon of R, in an aqueous alkali solution. By furtherdebutylization of the 2- substituted-4,6-t-butylresorcinol, 2-substituted resorcinolrepresented by the general formula: ##STR2## wherein R has the same meaning asdefined above, but the tertiary carbon of R is free from direct bonding to the benzenenucleus, is prepared.
