This step requires temperature control and control to make the reaction moderate and prevent excessive sulfonation.
Then, the obtained intermediate is hydroxylated. Appropriate alkali treatment is used to promote the conversion of the sulfonic acid group into the hydroxyl group to achieve the purpose of hydroxyl group introduction. During the process, the reaction conditions such as temperature and alkali concentration need to be precisely controlled to obtain high-purity products. In the catalytic mechanism of
, sulfuric acid can be used as a catalyst during sulfonation to reduce the activation energy of the reaction and accelerate the introduction of sulfonic acid groups; during hydroxylation, alkali catalyzes the conversion of sulfonic acid groups to optimize the reaction path and improve the reaction efficiency.
