Disclosed herein an improved process for producing 2,3-dihalopyridine with high purity at industrial scale with minimum effluent.

Process for producing dihalopyridines

A process for preparation of heteroaromatic nitrile from the corresponding alkyl pyridine is disclosed. The process comprises contacting the alkyl pyridine with ammonia and an oxygen source in the presence of a catalyst comprising an active component comprising of oxide of vanadium and antimony and a promoter provided on a support.

Process for the production of heteroaromatic nitriles improved catalyst therefor and a process for the production of said improved catalyst

An process for the preparation of pyridine and/or picolines is disclosed. The process comprises contacting a mixture of carbonyl compound with ammonia in the presence of surface-passivated titanium-silicate catalyst in gas phase at a temperature ranging between 300-500&#xb0; C., at gas space velocity in the range of 300 to 3000 hand at a pressure ranging between 1 to 10 atmosphere, condensing and separating the products by conventional methods and if desired, further purifying the product using well known conventional methods.

Process for the production of pyridine and picolines

The present invention relates to an improved and single step process for producing cyanopiperidine by dehydrating respective piperidine carboxamide employing a suitable dehydrating agent.

Process for producing cyanopiperidine

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&#xb0;-210&#xb0; 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.
