P-toluene sulfonic acid is a white acicular crystal or crystalline powder is a kind of strong organic acid (acid), sulfuric acid is stronger than the. The uniqueness of this acid is that it is usually the case for a solid, easy to use. Another advantage is that, compared with some inorganic acid is not oxidized, can replace inorganic acid in some cases.
