  • Single pot process for preparing metal nicotinates from beta-picoline
    Patent number: 7022853
    Abstract: The present invention relates to a single-pot process for the preparation of metal nicotinates, useful as a dietary supplement, from beta picoline as a source of the starting material, said process comprising the steps hydrosulfonation of beta picoline with sulfuric acid, heating the reaction mixture thus obtained to a temperature of about 150°-210° C. followed by oxidation with a suitable oxidizing agent to obtain nicotinic acid sulfate, reacting the nicotinic acid sulfate with a water soluble zinc and/or chromium salt to produce a solid metal nicotinate and separating it to thereby recover the corresponding metal nicotinates of high purity.
    Type: Grant
    Filed: October 29, 2002
    Date of Patent: April 4, 2006
    Assignee: Jubilant Organosys Ltd.
    Inventors: Nikhilesh Chandra Bhardwaj, Pradeep Kumar Verma, Agarwal Ashutosh

  • SINGLE POT PROCESS FOR PREPARING METAL PICOLINATES FROM ALPHA PECOLINE
    Publication number: 20020177584
    Abstract: The present invention relates to a single pot process for the preparation of metal picolinates useful as dietary supplement from alpha picoline, said process comprising hydrosulphonation of alpha picoline with sulphuric acid; heating the reaction mixture thus obtained between the range of 150° to 210 ° C. followed by oxidation with any suitable oxidizing agent to obtain alpha picolinic acid sulphate, and treating the thus obtained alpha picolinic acid sulphate with a metal salt solution to obtain corresponding metal picolinate.
