Preparation and Characterization of some Azo Phenolic Chlorinated Compounds and Their Application as Flame Retardant with Polyurethane

This study involves preparing some of the azo phenolic chlorinated compounds and studying their properties as a fire retardant with commercial polyurethane according to ASTM (American Society Test of Materials), where the use of ratios is adding different from azo phenolic chlorinated compounds. Azo phenolic chlorinated compounds were developed as a flame retarding material by increasing the chlorine atoms. The azo phenolic chlorinated compounds with different numbers and places of substituted chlorine atoms were prepared. Fourier-transform infrared spectroscopy (FT-IR) predicted the chemical structure of the azo phenolic chlorinated compounds. In addition, the efficiency of the sample increases as an inhibitor of fire, by increasing the number of chlorine atoms and increasing the proportion of azo phenolic chlorinated compounds added.
