VERFAHREN ZUR HYDROCYANIERUNG VON ORGANISCHEN ETHYLENISCH UNGESÄTTIGTEN VERBINDUNGEN |
摘要 |
<p>Ethylenically unsaturated organic compounds, for example diolefins, olefinic nitriles and monoolefins, are noncontaminatingly hydrocyanated into corresponding nitriles by (a) reacting such ethylenically unsaturated organic compounds with hydrogen cyanide in the presence of an aqueous solution containing a catalytically effective amount of a catalyst which comprises at least one nickel compound and at least one water-soluble phosphine, (b) thereafter separating the organic phase from the aqueous phase which result, the separated aqueous phase comprising a solid phase formed during hydrocyanation, and (c) thence treating the separated aqueous phase, or a solid phase removed therefrom, with hydrogen cyanide to thus at least partially dissolve said solid phase contained therein or removed therefrom.</p> |
