    摘要: The invention relates to the production of phosphorus-containing anticorrosive pigments with a particle size of at most 20 microns by reacting one or more calcium or magnesium compounds with phosphoric acid or acid alkali metal or ammonium phosphates by intimately mixing an aqueous suspension or solution of the reactants inside a dispersing means rotating at a speed of 3000 to 10,000 rpm. More particularly, fine pulverulent calcium and magnesium compounds are converted, with agitation, together with water and, if desired, a water-soluble alkanol to a homogeneous suspension or solution. The suspension or solution is intimately mixed, inside the dispersing means at 0.degree. to 40.degree. C. and in an approximately stoichiometric ratio, with the phosphoric acid or acid phosphate solution. Resulting and precipitated pigment is separated and dried under mild conditions while maintaining its content of water of crystallization. The anticorrosive pigment is comprised of a homogeneous mixture and/or mixed crystals of which 10 to 95 mol % is calcium hydrogen phosphate dihydrate, the balance being magnesium hydrogen phosphate trihydrate. An at least 55 weight % proportion consists of particles with a size of up to 5 microns with a BET-surface of at least 1 m.sup.2 /g.

    摘要: Production of halogen-containing tertiary phosphine oxides of the general formula (I) ##STR1## in which R.sub.1 stands for an alkyl, halogenoalkyl, alkenyl, halogenoalkenyl, alkinyl or halogenoalkinyl radical, each of these radicals containing from 1 to 18 carbon atoms, or stands for a cycloalkyl, a halogenated cycloalkyl, an aryl, a halogenated aryl, an aralkyl or a halogenated aralkyl radical, and X stands for halogen.The oxides are made by subjecting a compound of the general formula (II) ##STR2## in which R has the same meaning as R.sub.1 and X stands for halogen, to thermal treatment in the presence of hydrogen halide at atmospheric or at elevated pressure so as to split off water and formaldehyde in vapor form therefrom; by continuously freeing the resulting reaction mixture from the said components in vapor form; by terminating the reaction and thereafter stripping off the hydrogen halide from the reaction mixture by introducing an inert gas thereinto; and by purifying the remaining crude product by distillation or recrystallization.
