HETEROGENEOUS HYDROCYANATION
-
Paragraph 00031; 00032, (2015/07/07)
The present invention relates to an improved process for addition of hydrogen cyanide across olefins and, in particular, to the use of a specific aluminum oxide to catalyze the reaction. The aluminum oxide catalyst must have total alkali metal and/or alkaline earth metal content, measured in the form of alkali metal oxide and/or alkaline earth metal oxide, of less than 3,000 ppm by weight.
PROCESS FOR THE PRODUCTION OF NITRILE COMPOUNDS FROM ETHYLENICALLY UNSATURATED COMPOUNDS
-
Paragraph 0117-0124, (2013/03/26)
A method is described for the hydrocyanation of organic ethylene-unsaturated compounds into compounds including at least one nitrile function. Also described, is a method for the hydrocyanation of a hydrocarbon compound including at least one ethylenic unsaturation by reaction in a liquid medium with hydrogen cyanide in the presence of a catalyst including a metal element selected from among the transition metals and an organophosphorous ligand including, in one embodiment of the invention, an organophosphorous compound. The described method can be used in particular for the synthesis of adiponitrile from butadiene.

Ligand maps lead to treasure! The activity of complexes of fluorophosphines (R2PF) in catalytic hydroformylation and hydrocyanation is predicted from a ligand map. However, the instability of R2PF to disproportionation is well-documented. Examples of R2PF ligands (see scheme) are described that are stabilized to such an extent that they can be used in catalysis and are shown to be highly effective.
