摘要
温控非水液 /液两相催化 ,是指一类由两种或多种液态有机物组成的催化反应体系 ,其特点是体系的相态变化可通过温度来调控 ,即体系在高温时相互混溶呈均相 ,低温不溶分成两相 ,催化剂和产物分别处于两相 ,从而为解决均相催化剂分离难的问题开拓了一个新方向 ,是液 /液两相催化研究领域最引人注目的进展之一 .首次以“温控”为主线将氟两相催化作为温控液 /液两相催化的一个特定类型纳入“温控非水液 /液两相催化”范畴 ,并与其它通过温度来调控的有机液
Thermoregulated non-aqueous liquid/liquid biphasic catalysis system is a kind of catalysis system composed of two or three organic solvents, in which phase conversion can be regulated by temperature. This system is miscible and homogeneous at high temperature but converts into two phases at low temperature. The catalysts and products are in different phases and can be separated conveniently by phase-separation, which solves the difficult problem of catalyst separation in homogeneous catalysis. So the thermoregulated non-aqueous liquid/liquid biphasic catalysis is one of the most attractive progresses in the research field of liquid/liquid biphasic catalysis. In this paper, fluorous biphasic catalysis, which is believed to be one special example of the thermoregulated liquid/liquid biphasic catalysis, other thermoregulated organic liquid/liquid biphasic catalysis, and thermoregulated phase separable catalysis are described in detail.
