titleOfInvention | Preparation of unsaturated nitriles |
abstract | An olefinically unsaturated nitrile, an olefinic hydrocarbon containing an allylic hydrogen, and a monoadduct reaction product of an olefinic hydrocarbon and an olefinically unsaturated nitrile are contacted in a plurality of reactors in series in the presence of a diluent to produce unsaturated dinitriles. At least a portion of the olefinically unsaturated nitrile is added directly to at least one of the reactors other than the first reactor in the series to reduce the production of heavies having a boiling range greater than the unsaturated dinitrile. At least a portion of the diluent is added directly to at least one of the reactors other than the first reactor in the series to reduce the production of undesired middle byproducts having a boiling range between the monoadduct reaction product and the unsaturated dinitrile. |
