歧化松香生产的研究进展

文章介绍了歧化松香生产的改进方法集中在工艺路线和催化剂两个方面,工艺路线有连续法、间歇法、熔融法和溶剂法,催化剂有贵金属和非贵金属两种类型,目前工业化生产采用的主要是贵金属催化剂,而非贵金属催化剂正在开发研究当中,并比较了各种方法的歧化反应工艺条件及改进的措施。

Research progress for producing disproportionated rosin

The progress of producing disproportionated rosin focuses on the technique and the catalyst. The technique includes the continuous method, the intermittent method, the melt method and the solvent method. The article compares these conditions and the improved measures. The catalyst to this reaction can be divided into noble metal catalyst and non-noble metal catalyst. At present most industries adopt the noble metal catalyst for producing. And the non-noble metal catalysts are in the progress of research. The paper compared process conditions and improved measure of different disproportionated reaction too.
