p-Toluenesulfonic Acid Monohydrate (CAS: 6192-52-5) is used for synthesis of doxycycline on medicine, dipyridamole, amoxicillin, hydroxyl ammonia benzyl cephalosporin intermediates such as important raw material; Widely used in organic chemical industry; In dilute acid ester c, textile auxiliaries, photographic film, polymerization of stabilizer and organic synthesis catalyst (esters); In resin, paint, man-made board, casting, paint and other industries are widely used as curing agent, and curing speed, the film does not change color; Is also a synthetic ethoxy quinoline important raw materials, also widely used in pesticide synthesis industry, also used as electroplating intermediates. p-Toluenesulfonic Acid Monohydrate, an oxonium salt, is an inexpensive and easy to handle organic catalyst used in organic synthesis. The study of its crystalline structure shows that it is monoclinic with P21/c space group. p-Toluenesulfonic Acid Monohydrate is used as catalyst and stabilizer in reaction units such as lipidation, dehydration, alkylation, dealkylation, Beckmann rearrangement, polymerization and depolymerization. Epoxy and amino resins, coatings and other aspects are also used.
