Abstract

Abstract Several K 2Cr 2O 7 supported reagents on inert solids have been obtained by deposition of K 2Cr 2O 7 on different solids.A1PO ,BPO and solid mixtures BPO -A1PO are used as supports. The K 2Cr 2O 7 is deposited on solid as large crystals detected by an X-ray diagram in the Cr50 and Cr25 series giving solids with very low surface areas.The number of acid and oxidizing sites is dtermined.Solids supports with small surface areas and large pore diameter give K 2Cr 2O 7 supported reagents with higher activity than those obtained from solids with high surface areas and large pores.
