    摘要: A process is provided for preparing an aryl diphosphate ester containing less than 5% by weight of triarylphosphate. The process reacts a solution of a dihydroxy aromatic compound and an excess of phosphorus oxychloride in a nonaqueous solvent having a boiling point greater than 110.degree. C. The excess phosphorus oxychloride and part of the solvent are distilled from the solution at atmospheric pressure and the intermediate, a diphosphotetrachloridate solution, is reacted with a monohydric aryl compound. After extracting with an aqueous, alkaline solution the product is recovered by distilling off the remaining solvent.

    摘要: A reactive fire retardant mixture useful in the preparation of polyurethane foams. The mixture contains a halogenated imide-containing polyol having the formula: ##STR1## and the corresponding ether having the formula: ##STR2## wherein R is a hydrocarbon group having the valance n+2 and is selected from the group consisting of benzene groups, naphthalene groups and alicyclic hydrocarbon groups containing 5 to 10 carbon atoms, R' is an aliphatic hydrocarbon group containing 3-12 carbon atoms, X is selected from the group consisting of bromine and chlorine, n is an integer from 1-6 and p is an integer from 2-6. They are prepared by reacting an alcohol (e.g. isopropyl alcohol), a halogenated dicarboxylic anhydride (e.g. tetrabromophthalic anhydride) and an aminopolyol (e.g. 2-amino-2-ethyl-1,3-propanediol).

    摘要: An additive flame retardant bisimide containing halogen atoms and ammonium acid tetrahalophthalate, e.g. N,N'-bis(2-ethylene tetrabromophthalimide) ammonium acid tetrabromophthalate. These compounds are useful in a variety of polymeric compositions and demonstrate increased thermal stability. They also foam on decomposition with the evolution of gas thus readily lending themselves to the preparation of flame retardant coatings.

    摘要: A process for photochlorinating aromatic compounds in the side chain and, in particular, a process for the selective chlorination of a 2-alkyl group of 2-alkyl benzoic acid or ester is disclosed. In this process, hydrogen chloride is added to the benzoic acid or ester prior to adding chlorine in the presence of actinic radiation at a reaction temperature below the decomposition temperature of the resulting chlorinated acid or ester. A typical aromatic compound is methyl 2-methylbenzoate and the reaction is preferably carried out at a temperature ranging from about -20.degree. C. to 20.degree. C.

    摘要: A normally liquid, flame retardant polyol ester prepared by a process comprising reacting a halogen containing anhydride of a dicarboxylic acid or a mixture of said anhydrides with an aliphatic polyol having at least three hydroxy groups and an aliphatic diol, to obtain a substantially fully esterified halogen containing product in which the acid number does not exceed 10, with the optional removal of unreacted diol during the course of the reacting or subsequent to the reacting. This flame retardant polyol ester may be used in the preparation of polyurethanes or polyesters.
