| Abstract: | The dehydration reaction of cyclohexanol was carried out in the presence of silica gel supported phosphoric acid as catalyst under solvent-free conditions.This method has several benefits including simple simpleness,short reaction time(1.5 h),mild reaction conditions and low pollution.The results showed that there is no influence on the yields of products when catalyst has be regenerated and used after 5 times. |
