    摘要： A novel scheme for olefin recovery/separation based on the redox properties of metal dithiolene complexes is described. The complex, [1,2-bis(cyano)ethylene-1,2-dithiolato]nickel, [Ni(S2C2(CN)2)2], when generated electrochemically, binds olefin to form an adduct. The olefin is released when the olefin adduct is reduced electrochemically. The reduced form of the metal dithiolene complex can then be re-oxidized to complete the cycle. For olefins such as 1-hexene, propylene, and ethylene, fast olefin binding and release is observed when modulated electrochemically. Olefin binding/release rates are fast as compared to the electrochemistry experiment (second or sub-second time-scale).

    摘要： The present invention is related to a method for oligomerizing olefinic monomers under oligomerization conditions to form higher olefins. The novel method comprises contacting a feed comprising the olefinic monomers with a catalyst composition comprising the reaction product of: (a) a compound having a formula selected from the group consisting of M[S2C2(RaRb)]2 and M[S2C6(R1R2R3R4)]2, wherein M is a late transition metal, Ra, Rb, R1, R2, R3 and R4 are independently selected and may be the same or different and are selected from hydrogen, electron-withdrawing groups and unsubstituted and substituted hydrocarbyl groups; and (b) an activating cocatalyst. The improved method advantageously relates to oligomerizing olefinic monomers from feed streams having contaminants, especially sulfur-containing contaminants.

    摘要： Enhanced synthesis of transition metal dithiolene complexes is described. [1,2-bis(Trifluoromethyl)ethylene-1,2-dithiolato]nickel selectively and reversibly binds olefins (C.sub.2 to C.sub.6). Under the same conditions, the complex does not react with H.sub.2 O, C.sub.2 H.sub.2, CO, and H.sub.2, and only slowly reacts with H.sub.2 S at high concentrations. The compositions are useful for selective removal and recovery of olefins from process streams containing contaminants such as CO and H.sub.2 S.
