Study on Catalytic Action of Heavy Metal-Glycidyl Homo Polymer I. Decomposition of Hydrogen Peroxide by Cobalt-Glycidyl Homo Polymer

摘要

The catalytic action of a metallic salt supported by glycidyl homo polymer (abbreviated as GHP), the polymerization product of epichlorohydrin with sodium hydroxide, was evaluated by the decomposition of hydrogen peroxide. These metallic salts used were : nitrate, sulfate, acetate, formate and chloride of chromium, manganese, cobalt, nickel, iron and copper. A catalyst was prepared by the impregnation of a metallic salt into GHP. Preliminary experiments revealed that the catalytic action of following metallic salts supported by GHP were superior to those unsupported by GHP ; chromium(III) chloride, manganese(II) nitrate, manganese(II) sulfate, manganese(II) chloride, cobalt(II) nitrate, cobalt(II) sulfate, cobalt(II) acetate, cobalt(II) chloride, nickel(II) nitrate and Nickel(II) chloride. A further research was made for cobalt salt-GHP. The catalytic action of cobalt(II) acetate-GHP was superior to that of the other cobalt salt-GHP and affected by the method of preparation.
