  • Organic-inorganic hybrid chiral sorbent and process for the preparation thereof
    Patent number: 9272261
    Abstract: 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.
    Type: Grant
    Filed: July 30, 2013
    Date of Patent: March 1, 2016
    Assignee: Council of Scientific & Industrial Research
    Inventors: Syed Hasan Razi Abdi, Rukhsana Ilyas Kureshy, Noor-ul Hasan Khan, Raksh Vir Jasra, Vishal Jitendrabhai Mayani, Santosh Agrawal
