This method has several advantages such as high to excellent product yields in short time, using an inexpensive and reusable catalyst and available starting material.展开更多

It is shown that the selective of epoxidation propylene decreases while the selective of propylene glycol increases, when the water content increases in the mixed solvent of methanol/water.展开更多
