The present invention provides an organic-inorganic hybrid chiral sorbent for chiral resolution of various racemic compounds viz. racemic mandelic acid, 2-phenyl propionic acid, diethyl tartrate, 2,2′-dihydroxy-1,1′-binaphthalene (BINOL) and cyano chromene oxide with excellent chiral separation (enantiomeric excess, 99%) in case of mandelic acid under medium pressure column chromatography. These optically pure enantiomers find applications as intermediates in pharmaceutical industries.
本发明提供了一种有机-无机混合手性吸附剂,用于手性分离各种外消旋化合物,如外消旋
苹果酸、
2-苯基丙酸、
酒石酸二
乙酯、2,2'-二羟基-
1,1'-联萘(BINOL)和
氰基色素氧化物,在中等压力柱层析条件下,外消旋
