  • Adsorption of malathion on thermally treated egg shell material

    Thermally treated egg shell materials were prepared at different temperatures. The samples were investigated by means of FT-IR and thermogravimetric analysis (TGA). The adsorption behaviour of malathion on egg shell and its thermally treated samples was studied using batch method and gave uptake capacities up to 0.964 mmol/g. Adsorption kinetics as well as the adsorption isotherms were discussed. ...

  • Effect of Microencapsulation and 4A Zeolite on the Properties of Intumescent Flame-retardant Natural Rubber Composites

    A novel microencapsulated intumescent flame retardant (MIFR) agent containing 4A zeolite has been prepared. The morphology of MIFR agent is characterized by transmission electron microscopy (TEM). Properties such as cure and tensile characteristics, thermogravimetric analysis (TGA), and flame-retardant (FR) properties are researched and compared. The addition of this MIFR agent into natural ...

  • Synthesis and TGA Evaluation of Novel Triphosphate Esters

    Several new substituted organo tri/thiotriphosphate esters were synthesized by condensing cyclic oxaza/dioxaphosphorochloridates/ thiochloridates with K2HPO4 in the presence of tetrabutylammonium iodide. The functionality on the phosphate was systematically changed by synthesis, thus allowing evaluation and comparison of a range of phosphate esters with highly varied structural features. They ...
