Use of p-Toluenesulfonic acid

Medical for the synthesis, amoxicillin pharmaceutical intermediates and other important raw materials; in the organic chemical industry was widely used. In acrylics, textile auxiliaries, photographic films, polymerization stabilizers and organic synthesis (ester) catalyst; in the resin, paint, wood-based panels, casting, paint and other industries are widely used as a curing agent, and the fixed speed Fast, the film does not change color; but also an important source of synthetic ethoxyquin. In the pesticide synthesis industry is also widely used (dicofol) chloramine T, pigments; CLT acid.
