Synthesis of acetophenone cylic ethylic ketal catalyzed by sulfamic acid;

Synthesis of acetophenone cylic ethylic ketal by the solid superacid S_2O_8~(2-)/Fe_2O_3-CoO catalyst;

the optimum conditions for the synthesis of acetophenone cylic ethylic ketal were obtained by the orthogonal test,i.

The effects of cyclohexanone/ethylene glycol molar ratio,the amount of amino sulfonic catalyst,and species of solvent on the yield of cyclohexanone ethylene ketal have been investigated.

The catalytic synthesis of cyclohexanone ethylene ketal with p -toluene sulfonic acid, ferric chloride, tin bichloride, tin chloride, copper sulfate, ferric sulfate, ammonium ferric sulfate, cerium sulfate, zirconium chloride, sodium bisulfate, resin, resin supported Lewis acid, molecular sieve, solid super acid, niobic acid and so on were reviewed.

Synthesis of acetophenone ethylene glycol ketal using vanadium phosphorus oxide as heterogeneous catalyst;

Catalyzed by SO_4~(2-)-TiO_2/β-zeolite solid super acid,which was prepared through direct impregnation-calcination processes,acetophenone ethylene glycol ketal was synthesized from acetophenone and ethylene glycol.
