Abstract
Trimethylol propyl triacrylate was synthesized with acrylic acid and trimethylolpropane over solid super-acid SO2-4/TiO2.The effects of various amount of various amount of molar ratio of reactants and reaction time on synthesis were investigaled.The catalytic activity and inhibitor effectiveness of different catalysts and ploymerization inhibitor were compared.The otimum conditions were odtained as follows: the amount of catalyst is 5% of acrylic acid respectively,the mole ratio of trimethylolpropane to acrylic acid is 1∶3.8,reaction time is 6 h,under which esterification rate of 97% was attained.
