CHANGES IN CATALYTIC ACTIVITY OF BORON PHOSPHATES BY GRINDING

Abstract

Changes in catalytic activity and surface area of two boron phosphate samples by grinding were investigated. Grinding initially brought about increases in surface area and catalytic activity for the oligomerization of cis-2-butene. However, when ground for too long time, both surface area and catalytic activity decreased. Although two unground boron phosphate samples were different in activity and surface area, after grinding such differences became quite small.
