Abstract: This invention relates to a phosphate-based, corrosion inhibiting pigment consisting of 3 to 97 weight % of MgHPO4 ? 3H2O, the balance being CaHPO4 ? 2H2O. The pigment is used to avoid corrosion of iron and iron alloys and is employed in the form of a painting composition or paste. Up to 95 weight % of the pigment can be replaced by a pigment extender.

Abstract: PRODUCTION OF QUATERNARY PHOSPHONIUM HYDROXIDES Quaternary phosphonium hydroxides of the general formula: (I) in which R stands either for hydrogen or an aliphatic or aromatic hydrocarbon having 1 to 12 carbon atoms and n stands for 1 or 2, are made by reacting a di- or trimethylphosphine in an aqueous medium with an epoxide of the general formula (II) in which R has the meaning given above, More specifically a pH-value of ?12 is established in the aqueous medium by means of a base and the starting materials are mixed in said medium.

Abstract: PRODUCTION OF METHYLPHOSPHINE OXIDES Methylphosphine oxides of the general formula (I) (I) are produced from hydroxymethylphosphines of the general formula (II) (II) in which formulae R and R' each stand for identical or different alkyl-, cycloalkyl-, aralkyl- or aryl groups having from 1 to 18 carbon atoms, or carrying substituents being inert under the reaction conditions. The methylphosphine oxides are more particularly produced by subjecting the hydroxymethylphosphines to a rearrangement reaction with the aid of radical-yielding compounds.
