We developed the catalyst that the elution from the carrier surface to a liquid phase was controlled by temperature. The concentration of catalyst in solution was decided by the measurement of the UV absorption. It was confirmed that the catalyst components were desorbed from a carrier at reaction temperature and were adsorbed to a carrier at room temperature. The catalyst was efficient for halogen exchange reactions, easily recoverable using filtration, and reusable without loss of catalytic activity.

我们开发了一种由温度控制载体表面向液相洗脱的催化剂。通过测定催化剂的紫外吸收来确定催化剂在溶液中的浓度。结果表明，催化剂组分在反应温度下从载体上解吸，在室温下被吸附到载体上。该催化剂在卤素交换反应中效率高，易于过滤回收，且可重复使用而不损失催化活性。
