Process for the hydrocyanation of unsaturated nitriles to dinitriles |
| abstract |
The present invention relates to a process for the hydrocyanation of ethylenically unsaturated nitriles to saturated dinitriles, in particular the hydrocyanation of pentenenitriles to adiponitrile, one of the basic compounds for the production of polyamide 66. It consists more precisely of a process for hydrocyanation of an ethylenically unsaturated aliphatic nitrile, by reaction with hydrogen cyanide, in the presence of an aqueous solution of a catalyst comprising a compound of a transition metal and a sulfonated phosphine, characterized in that said solution also contains a cocatalyst consisting of at least one Lewis acid. |
