| Abstract: | Ditrimethylolpropane tetraacrylate(Di-TMPTA) was synthesized by direct esterification method with ditrimethylolpropane(Di-TMP) and acrylic acid as feed stock,silicotungstic acid supported on activated carbon as catalyst.The influences of acid/alcohol(mole ratio),amount of catalyst,reaction time,reaction temperature on esterification were investigated by orthogonal experiment,and the Di-TMPTA was characterized by Fourier transform infrared spectroscopy.The results showed that the eaterification rate reached ... |
| Keywords: | ditrimethylolpropane acrylic acid silicotungstic acid supported on activated carbon esterification ditrimethylolpropane tetraacrylate orthogonal experiment |
