2-Naphthalenesulfonic acid Use and Manufacturing
It is obtained by sulfonation of naphthalene. It is obtained by sulfonating at 160-166℃ with naphthalene as raw material and 98% sulfuric acid as sulfonating agent. During the sulfonation process, a small amount of α-naphthalene sulfonic acid by-product is generated. Using heating method, the unstable α-naphthalene sulfonic acid can be hydrolyzed at 140-150°C to remove the sulfonic acid group and become naphthalene and sulfuric acid. Use steam Then the naphthalene can be blown out. During the hydrolysis and blowing of naphthalene, a small amount of lye should be added to neutralize part of the sulfuric acid. It also reacts with naphthalenesulfonic acid to generate β-naphthalenesulfonic acid sodium salt crystals, which are filtered to obtain the finished product.
Peptone and protein determination. Dehydrogenation catalyst. Used in the production of 2-naphthol; 2-naphtholsulfonic acid; 2-naphthylaminesulfonic acid and other dye intermediates. The product is condensed with formaldehyde to produce a diffusing agent N (diffusing agent NNO).
