Particulate material reducing the ignitability of combustible substances

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)

Polyol pre-mixture for making flame-retardant poly-urethane foam plastics

The invention relates to a process for removing carbon black from an aqueous suspension obtained by washing a gas containing carbon black with water. To this end, a gas stream comprising hydrocarbons and at least one inert gas is introduced into a suspension having a solids content of from 0.5 to 4% by weight, at a temperature of from 10.degree. to 80.degree. C. In so doing, the carbon black agglomerates and collects on the surface of the suspension water from which it is separated, for example by skimming it off. The gas stream is produced by passing inert gas over the separated carbon black containing the hydrocarbons and heated to 200.degree. to 400.degree. C., the carbon black being converted into a dry, free-flowing material.

The invention relates to a corrosion-inhibiting active pigment for use in the surface protection of iron and iron alloys. The pigment consists of a mixture of calcium hydrogen phosphate dihydrate, magnesium hydrogen phosphate trihydrate and zinc oxide. More specifically, the mixture contains 2 to 98 weight % of ZnO and 98 to 2 weight % of phosphate components. These in turn contain 3 to 97 weight % of CaHPO.sub.4 .multidot.2 H.sub.2 O and 97 to 3 weight % of MgHPO.sub.4 .multidot.3 H.sub.2 O. The active pigment is suitable for use in painting compositions or lacquers.

The invention provides cleaning and detergent compositions containing about:

Detergent and cleaning compositions containing polymeric phosphate

The invention relates to a long chain ammonium polyphosphate and its use as an effective additive in lubricants and/or coolants for metal working under extremely high pressures and temperatures. The polyphosphate chain preferably contains 50 to 1000 phosphorus atoms. Up to 20% of the ammonium groups are replaceable by hydrogen. The additive is preferably added to the lubricant/coolant in a proportion of 0.1 to 30 weight %.

Additive for use in metal working

The invention provides cleaning and detergent compositions which contain about 0.2 to 5 weight % of at least one compound of the general formula (I) ##STR1## in which R stands for a hydrogen atom or a methyl group and R.sub.1 stands for a hydrogen atom or an alkali metal or NH.sub.4 -ion.

A process inhibiting the coalescence of flowable phosphorus pentachloride in a closed container. To this end, the invention provides for a readily volatizable organic liquid boiling within the range about 20.degree. to 200.degree. C. and being inert with respect to phosphorus pentachloride to be admitted to the container prior to, during or after the introduction of phosphorus pentachloride thereinto, and for the container to be then hermetically sealed, the liquid being used in a proportion of about 1 to 15 weight %, based on the quantity of phosphorus pentachloride.

Process inhibiting the coalescence of flowable phosphorus pentachloride

The invention provides stabilized pulverulent red phosphorus comprising a homogeneous blend of red phosphorus particles with a size of at most about 2 mm, aluminum hydroxide and a further metal hydroxide as oxidation stabilizers, wherein the metal hydroxide is lead hydroxide. The homogeneous blend contains aluminum hydroxide and lead hydroxide in a total proportion of about 0.1 to 6 weight %, based on the quantity of red phosphorus, the aluminum hydroxide and lead hydroxide, calculated as Al.sub.2 O.sub.3 to PbO, being used in a quantitative ratio of about 0.5 to 2.0.
