| titleOfInvention | A kind of method of alkene nitrile mixed solution By Direct Isomerization synthesis 3 pentene nitrile |
| abstract | The invention discloses the method for a kind of alkene nitrile mixed solution By Direct Isomerization synthesis 3 pentene nitrile, zero-valent nickel catalyst, phosphorus-containing ligand and Lewis acid is added in the alkene nitrile mixed solution comprising 2-methyl-3-crotononitrile and 3 pentene nitrile, there is isomerization reaction, generate the product comprising 3 pentene nitrile.Present invention eliminates the process of rectification under vacuum purification 2M3BN, be 3PN by the alkene nitrile mixed solution By Direct Isomerization under the effect of zero-valent nickel catalyst, Lewis acid, phosphorus-containing ligand comprising 2M3BN and 3PN, the transformation efficiency of 2M3BN is greater than 95%, the selectivity of 3PN is greater than 95%, and this method is compared with traditional method, and yield is substantially suitable, and owing to eliminating alkene nitrile mixed solution rectifying separation process, whole operational path is shortened, simplifies technical process, reduce equipment cost and production cost. |
