Solketal is widely used as organic solvent, plasticizer and pharmaceutical intermediates. A synthetic technique for solketal, which is characteristic of being catalyzed by sulfonic acid resin, was developed. Experimental results showed that the suitable synthetic conditions for solketal were as follows: mass ratio of two kinds of raw materials, glycerol to acetone, is 1:20, catalyst DT-851 sulfonic acid resin dosage is 5% (wt, calculated by glycerol), reaction temperature is 58 °C and reaction time is 2 h. The product solketal's yield is 95% w...
