溴化四丁铵的固－液相转移平衡研究

Study of BTBA on Solid-Liquid Phase Transfer Equilibrium

以溴化四丁铵（ＢＴＢＡ）作为固－液相转移催化剂，在不加入反应底物的情况下测定了它对某些酚钾盐及无机盐的固－液相转移平衡常数，结果表明，溴化四丁铵对这些盐类的固－液相转移反应的平衡常数较大，可以用作固－液相转移反应的催化剂。

With BTBA used as a solid-liquid phase transfer catalyst,without addition of a substrate,the solid-liquid transfer reaction equilibrium constants to some phenolates and inorganic salts are determined.The results show that the BTBA has larger equilibrium constants for such salts and can be used to catalyze solid-liquid phase transfer reactions.Tests demonstrated that the equilibrium constants are related with the crystal grating energy and stable constant of ion pair.
