    摘要: The object of the invention is a method for preparing 3-carboxy-4-hydroxybenzaldehydes and derivatives thereof from phenol compounds bearing formyl and/or hydroxymethyl groups in positions 2 and 4. Another object of the invention is the production of 4-hydroxybenzaldehydes from 3-carboxy-4-hydroxybenzaldehydes, and particularly the production of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, known as 'vanillin' and 'ethyl vanillin' respectively. The method for preparing 3-carboxy-4-hydroxybenzaldehyde is characterised in that the group in position 2 of the phenol compound bearing formyl and/or hydroxymethyl groups in positions 2 and 4 is selectively oxidised to a carboxylic group, and optionally a hydroxymethyl group in position 4 to a formyl group. By thereafter decarboxylating the 3-carboxy-4-hydroxybenzaldehyde, a 4-hydroxybenzaldehyde is obtained.
