    Abstract: Production of organophosphines of the general formula R.sub.n PH.sub.3-n, in which R stands for identical or different, substituted or unsubstituted alkyl, cycloalkyl or aralkyl groups having from 1 to 18 carbon atoms, preferably from 1 to 4 carbon atoms, more preferably from 1 to 2 carbon atoms, and n stands for a whole number within the range 1 and 3. The compounds are more particularly produced by continuously reacting hydrocarbon halides of the general formula RX, in which R has the meaning given hereinabove and X stands for halogen, especially for chlorine or bromine, with hydrogen phosphide, and primary or secondary organophosphines at temperatures within the range 100.degree. and 600.degree. C. and under pressures of up to 20 atmospheres in contact with a catalyst being placed in a reactor. Gaseous matter issuing from the reactor is cooled and the resulting organophosphonium halides (R.sub.n PH.sub.4-n)X are hydrolyzed in conventional manner to the corresponding organophosphines.

    Abstract: Alkyl phosphines of the general formula:R.sub.n PH.sub.3-n (I)are made. To this end hydrogen phosphide, a primary or a secondary phosphine is reacted with an alkylamine of the general formula:R.sub.n NH.sub.3-n (II)in a molar ratio of 0.1 to 10 mols of the alkylamine of formula II per mol of hydrogen phosphide or primary or secondary phosphine. The reaction is effected at a 150.degree. to 400.degree. C., at atmospheric pressure or a superatmospheric pressure up to 1 atmosphere gauge, and in contact with a catalyst comprising active carbon, copper (II) chromite, or one or more metals of Group Ib or VIII of the Periodic System of the elements. The starting materials are passed through a reaction zone at a rate which permits a contact time between them and the catalyst of 0.1 to 400 seconds.

    Abstract: Phosphine is produced from elementary yellow phosphorus and an aqueous alkali metal hydroxide solution in the presence of an alcohol. The phosphine is more particularly made by using an alcohol having from 5 to 10 carbon atoms and a dissolving power for yellow phosphorus of more than 5 g/l; suspending the phosphorus with agitation in the said alcohol in a reaction zone; reacting the resulting suspension with the alkali metal hydroxide solution at temperatures lower than the boiling point of the alcohol; and collecting the resulting issuing gaseous phosphine.

    Abstract: 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.

    Abstract: An aqueous alkali phosphate solution is made. An organic phase is countercurrently mixed with an aqueous phase, the two phases being used in a volume ratio larger than 1:1 and formed aqueous alkali phosphate solution is separated from the remaining organic phase. The two phases are mixed and reacted in a reaction zone comprised of a mixing and separating zone. The organic phase is continuously dispersed in the aqueous phase. A volume excess of aqueous phase is maintained in the mixing zone and the two phases are used in an overall quantity sufficient to provide a volume ratio of organic to aqueous phase of 4:6 to 2:8.
