Chiral P,N‐ligands for the highly enantioselective addition of diethylzinc to aromatic aldehydes

A new sterically hindered chiral P,N‐ligand was synthesized and successfully applied to copper catalyzed asymmetric addition of diethylzinc to aromatic aldehydes. Various aromatic aldehydes can react smoothly to give the corresponding addition products with good to excellent enantioselectivities, which provides a readily accessible method for the preparation of chiral secondary alcohols.

三出口萃取工艺静态平衡研究

三出口萃取工艺是在普通分馏萃取工艺中间级增开一个出口使之同时分离三个组份。采用这一工艺可大大简化多元体系分离流程,提高经济效益。本文根据恒定总萃取比体系的本出口萃取工艺中各组份的静态物料平衡,推导出四种三出口萃取工艺的极值公式。通过计算机静态模拟计算确定了Gd/Tb/Dy三出口萃取工艺参数,并通过试验验证了计算结果。
