  Character description:
  White crystal plate, generally for two water crystal substance, soluble in water (20 ℃ 67 g, 80 ℃,260 g), methanol soluble in most organic solvents, slightly soluble.And 20g/L solution pH = 8-10。melting point>300℃,point of flammability>500℃。Generally by toluene as raw material, followed by sulfonation, get to methyl benzene sulfonic acid, reoccupy liquid alkali neutralization and system crude products, then decoloring, concentration, crystallization, centrifugal have finished;Can also by p-toluene sulfonyl chloride hydrolysis and have to (must be strictly controlled hydrolysis temperature, prevent impact material, alkaline hydrolysis, under the condition of the hydrolysis temperature increase speed. Under normal temperature hydrolysis slower, more than fifty ℃ hydrolysis rate significantly speed up).
  Useful:
  Mainly used in organic synthesis industry, in medicine for synthetic doxycycline and dipyridamole, naprosyn and used in the production of amoxicillin, cefadroxil intermediates.
