摘要： The invention provides methods useful in the industrial scale process for hydrocyanation of butadiene to adiponitrile for recycle of unwanted byproduct 2-methyl-3-butenenitrile (2M3BN) by conversion to process intermediate pentenenitrile. The invention provides a process for generating catalysts useful for carrying out the hydrocyanation of butadiene to adiponitrile, the process comprising contacting the 2M3BN and a solution of a nickel-ligand catalyst in cis-2-pentenenitrile (cis-2PN), trans-2-pentenenitrile (trans-2PN), or a mixture thereof. The improved methods of the invention can provide improved catalyst solubility for bidentate ligands without a requirement for a Lewis acid catalyst promoter such as zinc chloride to be present.

摘要： An integrated process for making di-functional or multi-functional molecules with concurrent light paraffin upgrading is disclosed. The process involves three primary steps: (1) oxidation of an iso-paraffin to alkyl hydroperoxide and alcohol; (2) converting the alkyl hydroperoxide and alcohol to dialkyl peroxide; and (3) coupling functional molecules into di-functional or multi-functional molecules using the dialkyl peroxide as a radical initiator, while the dialkyl peroxide is converted to a tertiary alcohol. The functional molecules include any functional molecule R—X, where R is a hydrocarbyl group and X is a functional group such as —OH, —CN, —C(O)OH, —NH—, or the like.

摘要： An improved multi-reaction zone process provides improved nitrile product quality and yield. In a first reaction zone, 1,3-butadiene is reacted with hydrogen cyanide in the presence of a catalyst to produce pentenenitriles comprising 3-pentenenitrile and 2-methyl-3-butenenitrile. In a second reaction zone, 2-methyl-3-butenenitrile, recovered from the first reaction zone, is isomerized to 3-pentenenitrile. In a third reaction zone, 3-pentenenitrile recovered from the first and second reaction zones is reacted with hydrogen cyanide in the presence of a catalyst and a Lewis acid to produce adiponitrile. Unwanted production and build-up of dinitriles, including methylglutaronitrile, in the first reaction zone for the hydrocyanation of 1,3-butadiene is prevented by limiting the flow of Lewis acid into the first reaction zone.

摘要： A hydrocyanation reaction is used to react 1,3-butadiene with hydrogen cyanide in the presence of a catalyst to produce pentenenitriles, as well as reaction byproducts, such as methylglutaronitrile (MGN). The effluent from the hydrocyanation reaction is distilled in a particular manner to produce a pentenenitrile-enriched stream, a catalyst-enriched stream and a stream enriched in methylglutaronitrile (MGN). At least a portion of the catalyst enriched stream may be recycled to the hydrocyanation reaction. 3-pentenenitrile may be recovered and, optionally, further reacted with HCN to make adiponitrile (ADN).
