<正>研究了马尾松松节油和苯酚反应的规律,选定了较为理想的Lewis酸催化剂体系,获得了最佳工艺条件。用甲苯为溶剂,催化剂量为总原料的4％,松节油和苯酚的摩尔比控制在1:0.5～1:0.7的范围内,在25～50℃下进行Friedel-Craft’s反应,经水洗、蒸馏等工序,可得加特纳色阶为7～9的淡黄色树脂,其得率在90％以上(以总反应物料重量计),软化点达115℃以上。本研究得到的萜烯酚树脂经应用试验表明,在橡胶、保护膜胶带等工业中可提供特有的性能,具国外同类产品水平。并为实现萜烯酚树脂工业生产提供了可靠依据。

Based on the study of reaction between turpentine from Pinus massoniana and phenol, an optimized catalyst system was used to obtain the best processing condition. Friedel-Craft’s reaction was carried out between turpentine and phenol at molar ratio of 1:0.5?:0.7 with 4% of catalyst in reactants at temperature of 25?0-. A pale yellow resin with Gardner Color 7? and soft point over 115- was obtained at a yeild above 90% (in the weight of the total raw materials used). The prepared resin was found useful in rubber and protecting tape industries according to results of application. The study provides some reliable data for further industrial testing.
