Abstract
10-Undecenal glycol acetal is synthesized from 10-undecental and ethylene glycol using vitamin C as catalyst.The effects of mole ratio of reacants,reaction time,catalyst dosage and dosage of water-carrying regent on the yield of 10-undecenal glycol acetal are investigated.The best reaction conditions are as follows:the amount of 10-undecental is 0.1 mol,the molar ratio of 10-undecental/ethylene glycol is 1.0/1.2,the amount of catalyst is 0.2 g,the amount of cyclohexane is 10 mL,reaction time is 3.0 hours.The yield can reach 82.6%.
