A process for preparing alkoxyalkyl-substituted phenols represented by formula (1), (wherein R', R2, and R3 each represents a hydrogen atom or an alkyl group, and R4 represents an alkyl group) in a high yield and with a high selectivity. The process comprises reacting a phenol with an alcohol in the presence of a catalyst selected from the group consisting of a tertiary alkylamine, a tertiary unsubstituted benzylamine, a mixture of a tertiary alkylamine with a tertiary unsubstituted benzylamine, an alkali metal carbonate, an alkali metal bicarbonate, and a mixture of an alkali metal carbonate with an alkali metal bicarbonate.
一种以高收率和高选择性制备式(1)代表的烷氧基烷基取代苯酚的工艺(其中 R'、R2 和 R3 各代表一个氢原子或一个烷基,R4 代表一个烷基)。该工艺包括在选自以下组别的催化剂存在下使苯酚与醇反应:叔烷基胺、叔未取代苄胺、叔烷基胺与叔未取代苄胺的混合物、碱金属碳酸盐、碱金属碳酸氢盐、碱金属碳酸氢盐与碱金属碳酸氢盐的混合物。
