Abstract: The invention relates to a particulate agent based on free-flowing pulverulent ammonium polyphosphates of the general formula H(n-m) ? 2(NH4)mPnO3n ? 1 in which n is an integer having an average value of from approximately 20 to 800 and the ratio of m to n is approximately 1, for impeding the combustibility of combustible materials. The agent is comprised of a) approximately 75 to 99 % by weight of ammonium polyphosphate, and b) approximately 1 to 25 % by weight of a hardened melamine and formaldehyde encasing the individual ammonium polyphosphate particles.

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 phosphorus-containing esters of the general formula in which X stands for an alkyl group having from 1 to 3 carbon atoms, an aryl group or an alkoxy group having from 3 to 6 carbon atoms, Y stands for an alkoxy group having from 3 to 5 carbon atoms, and Z stands for a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms or an aryl group by reacting phosphohalogen compounds of the general formula in which A and B each stand independently of one another, for a chlorine or bromine atom, an alkyl group having from 1 to 3 carbon atoms or an aryl group, C stands for a chlorine or bromine atom, and D stands for a free pair of electrons or an oxygen atom with aliphatic alcohols having from 3 to 6 carbon atoms. The phosphorus-containing esters are made by mixing and thereby reacting in an unheated reaction zone in liquid phase the phosphohalogen compound with the aliphatic alcohol and delivering the resulting reaction mixture to the head of a steam-heated packed column; feeding the column's base portion with inert gas travelling upwardly therein countercurrently with respect to the reaction mixture; distilling off overhead hydrogen halide, alcohol in excess and, alkyl halide, if any, together with the inert gas; partially condensing and removing the distilled matter; and removing resulting phosphoruscontaining ester flowing downwardly in the column from the column head to the column base, from the column base portion, if ?sired in admixture with alcohol in excess.
