  • Epichlorohydrin (ECH) Process

The main objective of the R & D project was to develop green, environmentally friendly technology for production of the epichlorohydrin by the oxidation of allylchloride using solid catalysts in a fixed bed tubular column reactor and to also establish downstream separation process (which backbone of Epichlorohydrin techonology) to purify epichlorohydrin from its impurity and unreacted allylchloride. To achieve the above-mentioned novel objective the compressive studies have been carried out with respect to the various process parameters (temperature, Allylchloride/hydrogenperoxie mole ratio, Allylchloride/methanol mole ratio, product mixture/water mole etc. required established cold extraction method) to optimize the reaction condition required for the plant operation. Based on compressive studies of data generated on Bench scale (15g TS-1 catalysts) Pilot plant scale (800g TS-1 catalysts),a epichlorohydrin Pilot Plant of capacity 3000 tone/year established in Thio Organic chemical Co. Ltd, Thioland by Adithy Birla Group.  Epichlorohydrin Plant is shown in following image.
