我觉得是这样的:最近,关于利用可溶性聚乙二醇载体分离回收昂贵的手性催化剂引起了广大的关注。
产品开发!

Recently, separation and recycling of the expensive chiral
catalysts utilizing soluble PEG (polyethylene glycol) polymer
supports have attracted a great of interest.8 The prominent
advantage of PEG-immobilized chiral catalysts lies in that
they are soluble in organic solvents, thereby allowing the
reaction to proceed homogeneously and display similar
activities and enantioselectivities to those of the homogeneous
parent systems. The recovery of the PEG-supported catalyst
from the reaction mixture can be readily achieved by filtration,
precipitation or extraction.原话是这样的,如果PEG都溶于反应体系了,后面如何分离呢,怎样还能沉淀,抽滤呢
