摘要
苯酚与烯丙基氯在70℃经醚化生成了苯基烯丙基醚,再经硅氢加成反应合成了苯氧基丙基三甲氧基硅烷,并用红外光谱认定了该化合物的特征峰。比较了3种催化剂:氯铂酸-异丙醇(Ⅰ),氯铂酸-四氢呋喃(Ⅱ)和氯铂酸-异丙醇-乙酰丙酮(Ⅲ)对苯基烯丙基醚与三甲氧基硅烷进行硅氢加成反应的催化性能以及反应温度的影响,发现当温度控制在80℃时,第3种催化剂的催化性能最优。
In this paper,phenol was reacted with allyl chloride at 70℃ , then the ether was reacted with trimethoxy silane to get phenoxy propyl trimethoxy silane through hydrosilylation at 80℃. The catalytic effect of three kinds of catalyst(I)platinum-isopropanol,(II) platinum-tetrahydrofuran, (III) platinum - acetylacetone and the effect of reacting temperature were discussed. In the second step, when the temperature was controlled at 80℃, III was the best for the reaction.
