Highly active phosphazenium chloride catalyst immobilized on SBA-15 mesoporous material in the chlorination of alcohols with phosgene
Author: Seo, Gon ; Kwon, O. Zoon ; Kim, Keun-Sik
A phosphazenium chloride catalyst immobilized on SBA-15 mesoporous material was prepared and applied to the chlorination of alcs. with phosgene.The physico-chem. property of the immobilized catalyst was characterized using several methods such as XRD, N2 adsorption, TG/DTA, FT-IR and NMR.Phosphazenium chloride was highly active in the chlorination of various alcs. and its activity was still retained even at immobilized state.The high activity of phosphazenium chloride catalysts was discussed in terms of the activation of chloride ions on phosphazenium nuclei.
