SYNTHESIS OF DIALKYL TETRABROMOPHTHALATES BY PTC AND THEIR FLAME RETARDANCY

Applied Chemistry Department, Shandong Institute of Building Materials, Jinan 250022

Received Date: 31 March 1995

Fund Project: The project was supported by the National Natural Science Foundation of China.

Eight dialkyl tetrabromophthalates(DATBPs) were synthesized by reacting tetrabromophthalic anhydride with excess alcohols which were used not only as a reactant but also as a solvent and using a quaternary ammonium salt as a phase transfer catalyst(PTC).The yields were found to be between 85-93%.Their structures were characterized by IR,NMR and elementary analysis.The flame retardant properties of the compounds were also studied.
