PRODUCTION OF ALKYLPHOSPHINES |
摘要 |
<p>PRODUCTION OF ALKYLPHOSPHINES Alkyl phosphines of the general formula: RnPH3-n (I) are made. To this end hydrogen phosphide, a primary or a secondary phosphine is reacted with an alkylamine of the general formula: RnNH3-n (II) in a molar ratio of 0.1 to 10 mols of the alkylamine of formula II per mol of hydrogen phosphide orprimary or secondary phosphine. The reaction is effected at a 150 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.</p> |
