METHOD OF 2-METHYLBUTENE-3-NITRILE ISOMERIZATION

摘要

FIELD: chemical technology. SUBSTANCE: isomerization of 2-methylbutene-3-nitrile to linear pentene nitrile is carried out in the presence of an aqueous solution at least one sulfonated phosphine and at least one transient metal compound. Pentene-3-nitrile is an intermediate compound used for adiponitrile synthesis. EFFECT: improved method of isomerization.
