Abstract: A process is described for preparing 3-pentenenitrile by hydrocyanating 1,3-butadiene in the presence of at least one catalyst, wherein unhydrocyanated 1,3-butadiene is removed from the effluent of the hydrocyanation and recycled into the process, and the recycled 1,3-butadiene is monitored for the content of hydrogen cyanide.

Abstract: A method for the production of 3-pentenenitrile by hydrocyanation of 1,3- butadiene in the presence of at least one catalyst, whereby 1,3-butadiene which has not been hydrocyanated is removed from the product from hydrocyanation and recycled into the process and the recycled 1,3-butadiene is monitored for hydrogen cyanide content.
