| Abstract: | A Brφnsted acid ionic liquid［Hnmp］HSO4 was used as the catalyst for esterification of acrylic acid with glycol. The influence of feed proportion, reaction temperature, reaction time, catalyst dosage and amount of water carrying agent was investigated. Glycol diacrylate yield of 90.9% was obtained under the optimial condition as follows：n(ethyleneglycol)∶n(acrylic acid)=1.0∶2.2，reaction time 60 min，reaction temperature （120-125） ℃, catalyst dosage=2.00% of the total material(mol)， the water carrying agent toluene dosage 20 mL. |
