摘要： The present invention concerns a process for the preparation of a 4-hydroxybenzaldehyde and its derivatives. More particularly, the invention concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, respectively known as vanillin and ethylvanillin. The process for the preparation of a 4-hydroxybenzaldehyde and its derivatives is characterized in that it consists of selectively oxidising, to a carboxy group, the group in the 2 position with respect to the hydroxyl group, present in the phenolic compounds in a mixture comprising at least a phenolic compound (A) carrying formyl and/or hydroxymethyl groups in the 2 and 4 position, a phenolic compound (B) carrying a formyl or hydroxymethyl group in the 4 position, a phenolic compound (C) carrying a formyl or hydroxymethyl group in the 2 position, resulting in a mixture comprising a 3-carboxy-4-hydroxybenzaldehyde, a 4-hydroxybenzaldehyde and a 2-hydroxybenzoic acid, which then undergoes a decarboxylation operation to produce the 4-hydroxybenzaldehyde and a phenol which can optionally be recycled.
摘要翻译：本发明涉及一种制备4-羟基苯甲醛及其衍生物的方法。更具体地，本发明涉及3-甲氧基-4-羟基苯甲醛和3-乙氧基-4-羟基苯甲醛的制备，分别称为香草醛和乙基香兰素。制备4-羟基苯甲醛及其衍生物的方法的特征在于，它包括以相对于羟基的2位选择性氧化羧基，所述基团存在于酚类化合物中，所述混合物包含至少在2位和4位含有甲酰基和/或羟甲基的酚类化合物（A），4位上带有甲酰基或羟甲基的酚类化合物（B），含有甲酰基或羟甲基的酚类化合物（C）组成2位，得到包含3-羧基-4-羟基苯甲醛，4-羟基苯甲醛和2-羟基苯甲酸的混合物，然后进行脱羧操作以产生4-羟基苯甲醛和可以任选地为回收。
