Abstract:Ethylene glycol cyclohexane ketal was synthesized under microwave irradiation from cyclohexanone and ethylene glycol in the presence of p-toluene sulphonic acid. The factors that influenced the reaction under microwave heating were investigated,the yield of 82.3% was obtained on condition of ethylene glycol ∶ cyclohexanone = 1.4 ∶ 1(mol/mol),p-toluene sulphonic were investigated acid:2.5 g/mol(based on the amount of cyclohexanone),cyclohexane:80 ml/mol,irradiation power:90 W,13 min. |
Key words:ethylene glycol cyclohexane ketal;p-toluene sulphonic acid;microwave synthesis |
