Abstract

PURPOSE: To obtain the titled compound, a starting material of pharmaceuticals, pesticides, etc., suppressing the formation of side products, by the reaction of a dihydric phenol and a sec-alkyl chloride in methyl or ethyl alcohol as a solvent, in the presence of an alkali metal hydroxide.
CONSTITUTION: A dihydric phenol, e.g. catechol, hydroquinone, etc., is made to react with a sec-alkyl chloride of formula I (R is CH3 or C2H5), e.g. isopropyl chloride, 2-butyl chloride, etc., 2W8 weight times, based on the phenol, of methyl or ethyl alcohol at 100W150°C in the presence of an alkali metal hydroxide or an hydroxide and a carbonate, to afford the objective compound. The formation of side products having alkylated aromatic carbon atoms can be suppressed. The presence of the carbonate inhibits the lowering of pH of the reaction mixture, and thus suppresses the side reaction. The molar ratios of the hydroxide and the carbonate to the dihydric phenol are pref. 0.75W1 and 0W0.25, respectively.
