Abstract (en)
[origin: WO2005073169A1] 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.
