  • 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.
