Preparation of potassium monopersulfate triple salt;

Metal hydrogen sulfates M(HSO4)n(Ca(HSO4)2,Zn(HSO4)2,and oxone) were used to catalyze one-pot three-component condensation reactions of aldehydes,1,3-dicarbonyl compounds,and urea at 90 ℃ under solvent-free conditions to give 3,4-dihydropyrimidin-2(1H)-one in high yields.

Synthesis of p-Nitro-ethyl benzoate with potassium bisulfate as catalyst;

Synthesis of butyl isovalerate synthesis catalyzed by potassium bisulfate

Normal propyl cinnamylate was synthesized by the esterification of normal propyl alcohol with cinnamic acid in the presence of potassium bisulfate monohydrate.

The results indicated that alkali metal sulfate and some heavy metal sulfate,especially potassium hydrogen sulfate and zirconium sulfate,has better catalytic ability than concentrated sulfuric acid to .

The results indicated that potassium hydrogen sulfate and zirconium sulfate had high catalytic activity.

Suitable factors of preparation of intermediate product potassium hydrogen sulfate and neutralizing reaction of potassium hydrogen sulfate with ammonia is given.

We have done a test and found that 5% of water-solution of potassium monopersulfate could effectively inhibit empoison of microorganism in production of edible fungi.
