| Abstract: | 10-Undecenal glycol acetal was synthesized from 10-undecental and ethylene glycol using p- aminobenzene sulfonic acid as catalyst.The effects of the mole ratios of reactants,reaction time and amount of catalyst on the yield of 10-undecenal glycol acetal were investigated.The optimum reaction conditions were found as follows.0.1 mol 10-undecental,the molar ratio of 10-undecental/ethylene glycol 1.0:1.2,0.5 g catalyst,12 mL cyclohexane,reaction time 2.0 h.Under the optimum condi- tions,the yield reached 92.4%. |
