| Abstract: | The condensation of acetophenone and ethylene glycol using vanadium phosphorus oxide heterogeneous catalyst was studied.The effects of reaction time,mole ratio of the reactants,catalyst dosage,dosage of water carrying agent on the yield of acetophenone ethylene glycol ketal were investigated.The results showed that the suitable conditions for the reaction are as follows: under refluxing,(0.10 mol) of ethylene glycol reacts with(0.12 mol) of acetophenone,catalyst dosage(0.20 g),(6 mL) of(cyclohexane) used as water carrying agent,reaction time 2.5 h.The yield achieved(81.5 %).The catalyst can be repeatedly used.The product was characterized by melting point and IR. |
