| 摘 要： | 通过理论分析和实验总结,研究了不同种类的碱性催化剂对酚醛树脂水溶性的影响,最后确定同时使用某种叔胺类化合物和少量氢氧化钡作为合成水溶性酚醛树脂的催化剂.在适宜的反应条件下,制得了游离酚含量和游离甲醛含量均较小的水溶性酚醛树脂.这种水溶性酚醛树脂可用于电气绝缘等诸方面.

| Abstract: | The effect of the kinds of basic catalysts on the preparation of water-soluble phenolic resol resin was investigated. The water-soluble resol was prepared by the reaction between phenol and formaldehyde with molar ratio 1:1.2~1.5 in the presence of catalysts at 80~85℃. The catalysts were made up of a kind of tertiary amine and a small amount of barium hydroxide. Free phenol content a nd free formaldehyde content in the water-soluble resol were not more than 10% and 1.4% respectively. This water-soluble resol is widely used in many applica tions such as plywood and insulation laminate. |
