| titleOfInvention | Method of producing straight-chain acrylonitrile dimers |
| abstract | Straight-chain acrylonitrile dimers including 1,4-dicyanobutene, 1,4-dicyanobutadiene and adiponitrile are produced at a high selectivity by dimerizing acrylonitrile in the presence of a ruthenium catalyst, and in the presence of a straight-chain dimer selectivity-enhancing agent comprising at least one member selected from (A) substituted benzoic acids, except for monoalkylbenzoic acids, having at least one substituent and preferably exhibiting a pKa of 1.50 to 6.0 determined in water at an ionic strength of 0 to 0.1 mole/liter at 25 DEG C.; (B) hetero atom-containing acyclic carboxylic acids having at least one substituent having a sulfur or nitrogen atom attached to a carbon atom located in an alpha - on beta -position with respect to a carboxyl group in a main hydrocarbon structure; and (C) 5 to 12 membered heterocyclic carboxylic acids having an oxygen, sulfur or nitrogen atom included in a 5 to 12 membered heterocyclic structure and a carboxyl or carboxymethyl group attached to a carbon atom located in an alpha -position with respect to the hetero atom. |
