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.
