SOLID ACID AND CATALYTIC PROPERTIES OF SILICA SURFACES MODIFIED WITH PHOSPHATE ION

Abstract

Solid acid property derived from phosphate ions with which the surface OH groups of silica gel fine particles were exchanged, and the catalytic activity were investigated. In the other paper the acid and catalytic properties regarding silica gels modified with phosphate and sulfate ions were reported. Here it was further more examined on the catalytic effect to the loading amount of phosphate ion.
