    摘要: Flame retardant flexible polyurethane foam compositions, methods of flame retarding flexible polyurethane foam compositions, articles made therefrom and flame retardants that comprise blends of (alkyl substituted) triaryl phosphate ester and phosphorus-containing flame retardant having at least about 5 wt. % phosphorus additives. The combined weight of the (alkyl substituted) triaryl phosphate ester and the phosphorus-containing flame retardant comprises about 5 to about 40% by weight of the flexible polyurethane foam compositions or reaction mixtures. The ratio of the (alkyl substituted) triaryl phosphate ester to the phosphorus-containing flame retardant is from about 95:5 to about 50:50 percent by weight.

    摘要: A method for preparing tetrabromobenzoate ester from a tetrabromophthalic anhydride including the steps of reacting the tetrabromophthalic anhydride with a catalyst and an alcohol at a temperature that favors partial esterification over complete esterification of the tetrabromophthalic anhydride to form a tetrabromophthalate half-ester reaction mixture; and feeding the half-ester reaction mixture to at least one reactor having and maintaining a temperature that favors decarboxylation over esterification to produce a tetrabromobenzoate ester-containing product. The temperature favoring partial esterification of the tetrabromophthalic anhydride is between about 70° C. and 130° C. The temperature favoring decarboxylation over esterification is between about 190° C. and 205° C. The tetrabromobenzoate ester-containing product comprises at least about 85% tetrabromobenzoate ester. The at least one reactor may include two or more reactors connected to one another in series.
