    Abstract: The disclosure relates to a storable polyol pre-mixture for making flame-retardant polyurethane foam plastics consisting of a mixture of a polyester polyol or polyether polyol and an ammonium polyphosphate as a flame-retardant agent. The pre-mixture contains more particularly an ammonium polyphosphate which corresponds to the general formula (I) H(n-m)+2(NH4)mPnO3n+1 (I) in which n stands for an integral average value of 100 to 1000, m stands for a whole number of up to n+2 and m/n stands for a value of about 1, has an acid number of 0.01 to about 5 mg KOH/g, contains 0.01 to 0.5 mass % water and 0.5 to about 15 mass % water-soluble fractions in water at 25 DEG C.

    Abstract: PRODUCTION OF TERTIARY PHOSPHINE OXIDES. Production of tertiary phosphine oxides of the general formula R1R2R3P(O), in which R1, R2 and,R3 each stand for identical or different, substituted or unsubstituted alkyl, aryl or aralkyl groups. The tertiary phosphine oxides are produced by oxidizing at temperatures higher than 200.degree.C one or more quaternary phosphonium halides of the general formula ¢R1R2R3R4P! X, in which R1 through R3 have the meanings given above, R4 has the same meaning as R1 through R3, and X stands for a halogen atom.

    Abstract: HOE 90/H 035 Stabilized red phosphorus, and processes for the preparation thereof of the disclosure: In, a stabilized, pulverulent red phosphorus comprising phosphorus particles having a maximum particle size of 2 mm whose surface is covered with a thin coating of an oxidation stabilizer, the oxidation stabilizer comprises an uncured epoxy resin in a proportion of from 0.2 to less than 5% by weight. The red phosphorus stabilized in this way may additionally be covered by a thin coating of di-2-ethylhexyl phthalate as phlegmatizing agent. In addition, processes for the preparation of the stabilized and possibly additionally phlegmatized red phosphorus are described.
