| abstract |
A method for reducing the content of hydrogen cyanide in a mixture containing pentenenitrile and hydrogen cyanide is provided. A method for reducing the hydrogen cyanide content in a mixture containing pentenenitrile and hydrogen cyanide, wherein the hydrogen cyanide content is reduced by removing hydrogen cyanide by azeotropic distillation using 1,3-butadiene. A method characterized by this was obtained. |
