| titleOfInvention | Improved allyl acetonitrile preparation method |
| abstract | The present invention, which provides, is applied to make the industrial scale process that butadiene hydrocyanation is adiponitrile the unwanted butene nitrile (2M3BN) of 2 methyl of accessory substance 3 by being converted into method intermediate allyl acetonitrile the method that recycles.The present invention provides a kind of method for being used to produce the catalyst for being applied to carry out hydrocyanation of the butadiene to adiponitrile, and the solution that methods described includes making the 2M3BN with nickel ligand catalyst in along 2 allyl acetonitriles (along 2PN), anti-2 allyl acetonitrile (anti-2PN) or its mixture contacts.The improved method of the present invention can provide improved catalyst solubility for bidentate ligand, without Lewis acid catalyst accelerator, such as zinc chloride be present. |
