paratoluenesulfonic acid

Buy paratoluenesulfonic acid wholesale in Ukraine

Solid white hygroscopic substance. It is highly soluble in water, alcohols, acetone, and other dipole organic solvents. It is insoluble in diethyl ether. It does not have clear melting points, therefore, their esters, acid chlorides or amides are used for identification. By acidity, toluosulfonic acids are comparable to H ₂ SO ₄ . Toluenesulfonic acids are obtained by passing toluene vapor through sulfuric acid, and prolonged heating with recooling of a mixture of toluene with NaH ₃ (S0 ₄ ). As a catalyst, r-toluenesulfonic acid is better, since the process proceeds with greater selectivity and with a higher yield of dipseudocumylmethane compared to the process in the presence of sulfuric acid. During crystallization, it has the form of colorless prisms; at 150 ° C, it undergoes hydrolysis.

Chemical formula - CH ₃ C ₆ H _5-n (SO ₃ H) _n .
