Abstract: Zirconium dibutylaminomethylphosphonate-phosphites Zr(HPO3)2-x·(O3PCH2N-Bu2)x·H2O (ZPDBN-ZP,x=0.8, 0.6, 0.5, 0.4,0.35) have been prepared for the first time. Partly quaternized ZPDBN-ZP with benzylbromide,zirconium (benzyldibutylammo-niomethy phosphonate bromide-dibuty ammoniomethy phosphonate-phosphite) Zr(HPO3)2-x·(O3PCH2NBu2)x-y·(O3PCH2N+Bu2PhCH2Br-)y·have been obtained. lion,esterification, Heterogeneous PTC reactions of H2O(ZPBBDB-ZPDBN-ZP,y
