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.

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.
