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： 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.
