| titleOfInvention | Recovery method of (meth) acrylonitrile |
| abstract | The present invention suppresses an increase in the pressure difference of the distillation column for recovering (meth) acrylonitrile and performs stable and efficient operation for a long time. As a method for recovering (meth) acrylonitrile from a mixture containing (meth) acrylonitrile, acetonitrile and an unsaturated compound, the mixture is introduced into a distillation column, and the (meth) acrylic acid is added to the top effluent of the distillation column. It distills on the conditions containing nitrile, and extracts acetonitrile from the top bottom and / or side stream of the said distillation column, and extracts the liquid containing an unsaturated compound at the point higher than the extraction place of the said acetonitrile, It is characterized by the above-mentioned. It provides a method for recovering (meth) acrylonitrile. |
