Naphthalene and sulfuric acid co-heat, control its temperature and duration, according to specific conditions, so that the sulfonic acid group enters the specified position of the naphthalene ring to obtain naphthalene derivatives containing sulfonic acid groups.
Then, in a suitable environment, the method of nitrification is carried out. Add a mixed acid of nitric acid and sulfuric acid, so that the nitro group enters the naphthalene ring to form a compound containing nitro and sulfonic acid groups.
Then by reduction, the nitro group is converted to the amino group. Iron powder, hydrochloric acid, etc. are often used as reducing agents. In a suitable reaction system, the nitro group is gradually converted to an amino group, and then 1-amino-8-naphthol-3,6-disulfonic acid is obtained.
Another way is to start from other compounds containing naphthalene structures and convert them in several steps. This purpose can also be achieved. First select a suitable naphthalene-based raw material, transform it into a functional group, such as hydroxylation, halogenation, etc., and gradually build the desired chemical structure. After appropriate modification and reaction, the acid is finally obtained.
