摘要/Abstract

摘要： 考察了不同的化学试剂、温度等对聚合松香汽油溶液洗涤效果的影响。结果表明,饱和草酸溶液和金属离子鳌合剂溶液具有较好的洗涤效果。工厂生产性实验结果表明金属离子鳌合剂溶液洗涤能使聚合松香色泽降低1个加纳色号。

Abstract: Effects of chemicals and temperature on color of polymerized rosin were investigated.The results showed that the chelating agent and oxalic acid exhibited a good washing performance in reducing color of the rosin. The Gardner color of the polymerized rosin produced in a factory with chelating agent was reduced for one grade.

Key words: polymerized rosin, purification, color
