摘要
采用自制的SO2 -4 /MxOy 型固体超强酸用作松香聚合催化剂。论文对影响反应过程的主要因素进行探讨。优化的工艺条件:固体超强酸用量5 % ~10 % ,反应时间3 ~5 h ,反应温度110~130 ℃,溶剂比1∶1 ~2 ,可获得符合标准要求的115 牌号的聚合松香产品。
Home made solid superacids SO 2- 4/MxOy were used as catalysts for rosin polymerization reaction and main factors affecting the reaction were investigated in the paper. The optimum conditions for the polymerization reaction were as follows:ratio of solid superacids to rosin 0.05~0.1(w/w), reaction time 3~5 h, polymerization temperature 110~130 ℃, ratio of rosin to solvent 0.5~1.0(w/w). Under these conditions the obtained products come up to specifications for 115 # of polymeric rosin standard.
