Thermal analysis study for nano hybrid Compounds and degradation degree of Thermal

Abstract

This study presents the synthesis of phenoxy herbicides Zn/Al-layered double hydroxides nano hybrids by the reaction of 2٬4-dichloro and 4-chlorophenoxy acetate nano composites using indirect method of ion exchange . These composites were characterize by thermal analysis (Thermal gravimetric (TG)and Differential thermal gravimetric (DTG) ). know weight change for Nano hybrid Compounds preparation both ethanol and watery medium when (Zn/Al= 2,3,4,5 ) when heating degree Thermal found when degradation for Nano hybrid Compounds , degradation degree Thermal for Nano hybrid Compounds preparation watery medium lower than degradation degree Thermal for Nano hybrid Compounds preparation ethanol medium , the molar ratio good for Nano hybrid Compounds preparation ethanol medium ( R=4) .
