    摘要: The invention relates to a process for making tertiary phosphines of the general formula R.sub.3 P, in which R stands for a linear alkyl radical having 2 to 4 carbon atoms. To this end, hydrogen phosphide is reacted with linear monoolefins having 2 to 4 carbon atoms. More particularly, the tertiary phosphine which is desired to be made is dissolved in an inert solvent and PH.sub.3 and monoolefin are reacted in the solution.

    摘要: Production of tertiary phosphine oxides which contain nitrile groups and correspond to the following general formula I: ##STR1## in which R.sup.1 and R.sub.2 each stand for a straight or branched, identical or different alkyl, cycloalkyl, aryl, alkylaryl or aralkyl group having 1 to 18 carbon atoms, and in which R.sup.1 or R.sub.2 may be identical with R, which stands for a radical of the following general formula II: ##STR2## in which R.sup.3 and R.sup.4 each stand for a straight or branched, identical or different alkyl, cycloalkyl, aryl, alkylaryl or aralkyl group having 1 to 18 carbon atoms, and/or hydrogen atoms. The tertiary phosphine oxides are made by reacting a phosphine of the following general formula III: ##STR3## in which R.sup.5 has the same meaning as R.sup.3 and R.sup.6 has the same meaning as R.sup.4 but is no hydrogen, with an .alpha.,.beta.-unsaturated nitrile of the following general formula IV: ##STR4## in which R.sup.3 and R.sup.4 have the meanings given above. The reaction is effected in a single stage in the presence of water or a water-solvent mixture and the above formula I compounds are separated from the reaction product.

    摘要: The invention relates to a process for making an isomeric mixture of secondary phosphines with the summation formula C.sub.20 H.sub.27 P. To this end, hydrogen phosphide is reacted with dicyclopentadiene in the presence of an agent yielding free radicals. More specifically, hydrogen phosphide and dicyclopentadiene are used in a molar ratio of 1 to at least 2 and the reaction is effected under a pressure of 5 to 90 bars. The mixture is used in the production of flotation aids and as an ingredient of catalytically active transition metal complexes.

    摘要: 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.
