标 题 :Process for synthesis of vinyl esters from butene oligomers
发明人：WIESE KLAUS-DIETHER; OLBRICH PAUL; GABRIEL JUERGEN
权利人:OXENO OLEFINCHEMIE GMBH
摘要:A process for the synthesis of vinyl esters from butene oligomers, wherein butenes are oligomerized, the butene oligomers are separated from the oligomerized mixture, the butene oligomers are converted to carboxylic acids which are longer by one carbon atom, and the resulting carboxylic acids are converted to the corresponding vinyl esters. The butene oligomers are in particular dibutene, tributene and tetrabutene. The invention also relates to the use of the vinyl esters as plasticizers or as comonomers in polymerization reactions.

摘要:A method for the direct stereospecific conversion of structurally diverse mono-, di-, tri- and tetra-substituted olefins to N—H, N-alkyl, N-cycloalkyl, or N-aralkyl aziridines using a hydroxylamine amination agent with transition metal catalyst. The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.

摘要:A process for the combined preparation of at least butene and octene from ethane, proceeds by a) providing an inert solvent having a boiling point or boiling range below the boiling point of butene; b) providing a first feed mixture comprising at least the inert solvent and ethene dissolved therein; c) converting the first feed mixture in a first synthesis; d) in the first synthesis, oligomerizing at least a portion of the ethene present in the first feed mixture in the presence of a first heterogeneous catalyst and in the presence of the inert solvent to obtain a first reaction mixture comprising at least the inert solvent, butene, hexene and octene; e) working-up of the first reaction mixture and/or a substance stream based thereon into a low boiler fraction comprising the inert solvent, at least one C4-fraction comprising butenes, a C6-fraction comprising hexenes, a C8-fraction comprising octenes and into a C8+-fraction comprising hydrocarbons having more than eight carbon atoms; f) using at least a portion of the low boiler fraction for providing the first feed mixture; g) providing a second feed mixture comprising at least hexene and ethene dissolved in the hexene using at least a portion of the C6-fraction; h) converting the second feed mixture in a second synthesis, wherein the second synthesis is spatially separated from the first synthesis; i) in the second synthesis, reacting at least a portion of the ethene present in the second feed mixture with at least a portion of the hexene present in the second feed mixture in the presence of a second heterogeneous catalyst to obtain a second reaction mixture comprising at least octene; and k) joint working-up of the second reaction mixture with the first reaction mixture or with the substance stream based thereon.
