Synthesis of a New Flame Retardant Decabromodiphenylethane;

In this paper, some synthetic technologies for 1,2-diphenylethane were summarized and discussed, which including Friedel- Crafts alkylation, benzyl chloride coupling reaction, benzoin reduction, alkylation of benzene and ethylene oxide, oxidative condensation of toluene and method of aromatization for ethyne.

Thermodynamic calculations for synthesizing 1,2-diphenylethane using benzene and 1,2-dichlorethane indicate that this synthesis process is a spontaneous strong exothermic reaction and can happen under room temperature.

It plays a very important role in determining the reaction process conditions and selecting the catalyst to analyze and calcu- late the reaction thermodynamic data of 1,2-diphenylethane synthesis from benzene and styrene alkylation reaction.
