Definitions
- the present invention relates to the manufacture of nitrile compounds from unsaturated organic compounds by reaction with hydrogen cyanide. It relates more particularly to the manufacture of nitrile compounds used for the synthesis of adiponitrile, an important chemical intermediate for the manufacture of large chemical compounds such as hexamethylene diamine and ⁇ -caprolactam. These last two compounds are used, in particular, in the manufacture of polymers such as polyamides and more particularly polyamides 6 and 6-6, or other polymers such as polyurethanes.
- nitrile compounds have been proposed.
- the direct hydrocyanation of an olefin or polyolefin such as, for example, 1, 3-butadiene by reaction with hydrogen cyanide is a process developed industrially and which is the subject of numerous patents or publications.
- This process consists, roughly, in a first step to carry out the addition of a molecule of HCN on an ethylenic unsaturation to obtain an unsaturated nitrile compound.
- this step leads to the production of many isomers of unsaturated nitriles.
- the addition of a new HCN molecule leads, in a next step to a polynitrile, for example, to a dinitrile such as adiponitrile when the starting olefin is 1, 3-butadiene.
- the process comprises, after the first hydrocyanation step, a step called “isomerization step” consisting in transforming the major part of the branched nitrile isomers in linear nitrile isomers such as, in the case of the hydrocyanation of butadiene, in 3- and 4-pentenenitriles.
- ligands are organophosphorus compounds such as phosphites, phosphinites, phosphonites or phosphines. They can be monodentates or polydentates. In the case of processes in a two-phase medium, these organophosphorus ligands advantageously comprise one or more ionizable groups such as the sulfonate, phosphate, carboxylate or ammonium groups, for example to make them soluble in the polar phase.
- French Patent No. 2,338,253 it also describes a process for the synthesis of adiponitrile by hydrocyanation of butadiene.

- US Pat. No. 5,773,637 describes the use, as Lewis acid, of the perfluoroalkylsulfonate compounds.
