| titleOfInvention | PROCEDURE TO PREPARE 3-PENTENONITRILE |
| abstract | A process for preparing 3-pentenenitrile is described, characterized by the following process steps: (a) reaction of 1,3-butadiene with hydrocyanic acid with at least one catalyst, obtaining a stream 1 containing 3- pentenenitrile, 2-methyl -3-butenonitrile, at least one catalyst and 1,3 butadiene, (b) distillation of stream 1 in a column, obtaining a stream 2 rich in 1,3-butadiene as a top product and a stream 3 poor in 1.3 Butadiene as a product as a discharge product, which contains 3-pentenenitrile, at least one catalyst and 2-methyl-3-butenonitrile, (c) distillation of stream 3 in a column, obtaining stream 4 as a top product containing 1, 3- butadiene, of a stream 5 in a lateral evacuation of the column containing 3-pentenenitrile and 2-butenonitrile, and of a stream 6 as a discharge product containing at least one catalyst, (d) distillation of stream 5 obtaining a current 7 as superior product, containing 2-methyl-3-butenonitrile, and a stream 8 as a discharge product containing 3-pentenenitrile |
