Procedure

A solution of bis(tribromoneopentyl)phosphorochloridate in benzene was stirred with water. Crystalline solids slowly came out, and were removed by filtration. The product was a colorless crystalline solid, m.p. 130° C. Titration with standard 0.1-N NaOH in aqueous acetone medium or KOH in methanol showed it to have an equivalent weight of 710 corresponding to [(CHBr)3CCH2O]2P(O)(OH), bis(tribromoneopentyl) hydrogen phosphate. The aqueous acetone sodium salt solution or the alcoholic potassium salt solution was applied to cotton polyester fabric to obtain a dry add-on of 20% of the alkali metal salt of bis(tribromoneopentyl) acid phosphate. Fixation of the finish was achieved by applying a solution of magnesium chloride, which gives in situ formation of the water-insoluble magnesium salt of bis(tribromoneopentyl) hydrogen phosphate. The resultant finish imparts flame retardant properties and is wash-durable.
