An advantageous process for producing cresols which comprises the steps of: preparing a solution of oxidation products containing tertiary and primary hydroperoxides by oxidizing cymene with oxygen, lowering the content of the primary hydroxides by the reaction of the above solution with both of an organic quaternary ammonium salt and an alkali, or an organic quaternary ammonium hydroxide, decomposing the resultant solution in the presence of a catalyst, and hydrotreating the decomposed solution.
一种有利的甲酚生产工艺包括以下步骤:通过用氧气氧化三亚甲基制备含有三级和一级氢过氧化物的氧化产物溶液,通过上述溶液与有机季铵盐和碱或有机季氢氧化铵的反应降低一级氢氧化物的含量,在催化剂存在下分解所得溶液,以及对分解后的溶液进行加氢处理。
