1,1′-双萘酚-4,4′-二醋酸酯和二异辛基碳酸酯的双酯交换 Ⅰ.催化剂的选择

Double Ester Interchange Between 1,1'-Bisnaphthol-4,4'-diacetate and Di(2-ethylhexyl) Carbonate Ⅰ. The Selection of Catalysts

本文探讨了不同催化剂的1,1′-双萘酚-4,4′-二醋酸酯和二异辛基碳酸酯的双酯交换,采用测定醋酸异辛酯生成速度的方法,比较了在相同反应条件下各催化剂的相对活性。色—质联用(GC—MS)分析结果表明,在1,1′-双萘酚-4,4′-二醋酸酯与二异辛基碳酸酯交换反应中,有相当量的庚酮生成。

The double ester interchange between 1,1'-bisnaphthol-4,4'-diacetate and di(2-ethylhexyl)carbonate catalized by various metal compound was investigated. The relative reactivity of catalysts was compared under the same reaction conditions by determining the amount of (2-ethylhexyl) acetate released during the reaction. GC/MS analysis showed that the heptanone was formed during the ester interchange reaction. One of the explanations is that the decomposition of reactants takes place in the process of reaction. It showed that the catalytic double ester interchange reactions are complicated ones.
