PRODUCTION OF ADSORBENT FOR DEODORIZATION

摘要

PROBLEM TO BE SOLVED: To effectively work the whole amount of an amino group-containing organic silicon compound carried on the surface of a carrier for adsorbing odor gas by increasing the introduction amount of the amino group-containing organic silicon compound against a hydroxyl group on the surface of the carrier and yet preventing the pores of the carrier from being blockaded by the excess amino group-containing organic silicon compound. SOLUTION: The adsorbent for deodorization is obtained by forming a carrier of a porous metallic oxide having many hydroxyl groups on the surface and carrying an organic silicon compound countering both a functional group capable of chemically combining with a hydroxyl group on the surface of the carrier and an amino group on the surface of the carrier. In this method, the carrier is immersed into a solution prepared so that an amino group-countering organic silicon compound becomes at least equal amount for the hydroxyl group on the surface of the carrier. Then, the carrier is washed to remove the excess amino group-containing organic silicon compound and thereafter dried. Pores of the carrier are prevented from being blockaded by polymerization of the excess amino group-containing organic compound by washing and removing the compound.
