| 摘要 |
<p>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.</p> |
