Abstract
Trimethylolpropane tris-acrylate (TMPTA) has been obtained by the reaction of trimethylolpropane (TMP) and acrylic acid (AA) with calcium sulfate whisker as catalyst and cyclohexane and toluene as water-carrying agent.The effects of ratio of TMP to AA and the amount of catalyst on the reaction were investigated.The results showed that esterification rate of TMPTA can reach above 96.8% and its purity is 97.6%,respectively,under optimal reaction conditions of n(AA)∶n(TMP)=3.40,catalyst concentration of 2.0%,mixed water-carrying agents and in the presence of polymerization inhibitor,reaction temperature 98 ℃,reaction time 5 h,flow of air 15 mL/min.
