摘要
A Brφnstd acidic ionic liquid HSO4 was used as catalyst in the esterification of acrylic acid and diethylene glycol.The influencing factors were studied.Under the optimized condition:n(diethylene glycol)∶n(acrylic acid)was 1.0∶2.4(0.1mol diethylene glycol,0.24mol acrylic acid),reaction time was 60 min,temperature was 115～120℃,the dosage of catalyst was 2.5% of the total reactants(mol),water-carrying agent was 30mL of toluene,the yield of the diethylene glycol diacrylate was 98.0% in the esterification of acrylic acid and diethyleneglycol glycol.
A Br nstd acidic ionic liquid [ Hnmp ] HSO4 was used as catalyst in the esterificafion of acrylic acid and diethylene glycol. The influencing factors were studied. Under the optimized condition：n（diethylene glycol） ：n（ acrylic acid）was 1.0：2.4（0. lmol diethylene glycol,0.24mol acrylic acid） ,reaction time was 60 min,temperature was 115 - 120℃ ,the dosage of catalyst was 2.5% of the total reactants （mol） ,water-carrying agent was 30mL of toluene,the yield of the diethylene glycol diacrylate was 98. 0% in the csterification of acrylic acid and diethyleneglycol glycol.
