果糖-邻苯二酚树脂胶粘剂的合成

Synthesis of fructose-pyrocatechol resin adhesive

用果糖和邻苯二酚在碱性条件下合成了环保型果糖-邻苯二酚树脂胶粘剂。根据中心复合设计实验原理,在单项因素实验的基础上,选取4因素2水平全因子的响应面分析优化方法,以产物的黏度为指标,得到了黏度与各影响因素的回归方程以及响应曲面图和其等高线图,进而得出合成树脂胶粘剂的最佳条件:反应物配比:n(果糖):n(邻苯二酚)=2:1,反应温度为71.3℃,反应时间为7.7h,催化剂用量为4.75%。

This environmental friendly phenolic resin adhesive was prepared under the alkaline condition using fructose and pyrocatechol.The viscosity was used as an index,basing on the single factor experiment,the combined effects of temperature,time,catalyst amount and material ratio were investigated and optimized using response surface methodology （RSM）.The optimum conditions of the reaction are gained： the molar ratio of fructose to pyrocatechol is 2 ： 1 , the reaction temperature is 71.3 ℃, the reaction time is 7.7 h, and the catalyst amount is 4.75%.
