| 摘 要： | 以对甲苯磺酸为催化剂,用1,1,1-三羟甲基乙烷（THME）与苯甲醛在四氢呋喃中反应,合成出2,2-二羟甲基缩苯甲醛丙醇；再以三乙胺作缚酸剂,用2,2-二羟甲基缩苯甲醛丙醇与甲基丙烯酰氯反应合成出甲基丙烯酸（2,2-二羟甲基）丙酯的缩苯甲醛衍生物,再与盐酸反应得到甲基丙烯酸（2,2-二羟甲基）丙酯。用核磁共振氢谱（1H NMR）证明了所合成化合物的结构。

| Abstract: | The 2,2-dihydroxymethyl propanol was first synthesized by the reaction of 1,1,1-tris （ hydroxymethyl） ethane （ THME ） with benzaldehyde in the presence of catalytic amount of TsOH. The methacrylation of 2 , 2-dihydroxymethyl propanol with methacryloyl chloride afforded the benzylidene acetal derivative of 2 , 2 -dihydroxymethylpropanyl methylacrylate. The resulting product was ensued by acid hydrolysis of benzylidene acetal to give 2 ,2-dihydroxymethylpropanyl methylacrylate. The structures of the products were verified by 1 H NMR spectra. |
