纳米镍催化树脂酸歧化反应的研究(Ⅰ)——树脂酸组成的研究

STUDY ON DISPROPORTION OF RESIN ACID CATALYZED BY NANOMETER NICKEL(I)——Study on Composition of Resin Acid

将纳米镍催化剂首次应用于树脂酸的歧化反应中。在溶剂存在条件下,进行松香的 歧化反应,对不同催化剂催化下的歧化松香组成尤其是酸性部分的组成进行了分析。将 DEAE-Sephadax离子交换色谱法应用于歧化松香酸性物与中性物的分离。对纳米镍催化松香 歧化过程中树脂酸的组成进行了跟踪分析。

Nanometer nickel was used as catalyst for disproportion of resin acid for the first time. In the presence of solvent, disproportion of resin acid using different catalyst was investigated, and the compositions of the products, especially acid parts, were analyzed. DEAE-Sephadax ion-exchange chromatography was used for separation of resin acid and neutral part in disproportionated rosin. During the reaction, the chemical compositions of disproportionated rosin have been traced.
