| titleOfInvention | Method for producing 3-pentenenitrile |
| abstract | An object of the present invention is to produce 3-pentenenitrile so as to be substantially free of 2-methyl-3-butadiene by hydrocyanation to 1,3-butadiene, circulate and use 1,3-butadiene, and use the catalyst as pentenenitrile. To provide a method for recovering and circulating the wastewater. (A) 1,3-butadiene is reacted with hydrogen cyanide on at least one catalyst to produce 3-pentenenitrile, 2-methyl-3-butenenitrile, the at least one catalyst, and 1, Obtaining a stream 1 comprising 3-butadiene, (b) distilling stream 1 in the column and using stream 2 enriched with 1,3-butadiene as the top product, 3-pentenenitrile, at least one of the above A stream 3 containing 2-methyl-3-butenenitrile and reduced 1,3-butadiene as a bottom product, (c) distilling stream 3 in the tower, A stream 6 containing at least one catalyst, with stream 4 containing butadiene as the top product and stream 5 containing 3-pentenenitrile and 2-methyl-3-butenenitrile as the side discharge of the tower. Stage obtained as bottom product (D) distilling stream 5 to obtain stream 7 containing 2-methyl-3-butenenitrile as the top product and stream 8 containing 3-pentenenitrile as the bottom product. It is characterized by. [Selection figure] None |
