Abstract: The invention relates to a method for producing linear alpha olefins by means of an isomerising metathetical reaction and ensuing ethenolysis. The method comprises the following steps: i) a C4-C10 olefin fraction is introduced into an isomerising metathesis reaction; ii) the mixture obtained is separated into a) a C2-C3-olefin fraction, b) a fraction containing olefins having the desired carbon count, c) a light fraction containing olefins having a carbon count of C4 or above, but below the carbon count of the desired fraction b) and, d) a heavy fraction containing olefins having a carbon count which is above the carbon count of the desired fraction b); iii) the light fraction c) and optionally the heavy fraction d) are redirected into the isomerising metathesis reaction i); iv) the fraction b) and optionally the fraction d) are introduced into an ethenolysis reaction; and v) the alpha olefin fraction produced in iv) is isolated. Linear C8-C12 alpha olefins can be especially produced using said method.

Abstract: In a process for producing alkoxybutenes, 1,3-butadiene or a butadiene-containing hydrocarbon mixture is reacted with an alcohol of formula ROH (I) at an increased temperature and pressure in the presence of a Brönsted acid, yielding a mixture of addition products of formulas (II) and (III), in which the radical R is a C2-C20 alkyl, alkenyl, cycloalkyl or cycloalkenyl group substituted or not with 1 to 2 C1-C10 alkoxy or hydroxy groups, or is a C2-C10 aryl or C7-C11 aralkyl group or a methyl group. The disclosed improvement consists in that the reaction is carried out in the presence of water.

Abstract: The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C 4 -olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.

Abstract: The invention relates to a catalyst comprising at least one complex of a metal of subgroup VIII which comprises at least one monodentate, bidentate or multidentate phosphinite ligand. The phosphorus atom and the oxygen atom of the phosphinite group are part of a 5 to 8-member heterocyclic compound. The invention also relates to a method for the hydroformylation and the hydrocyanation of compounds, said compounds containing at least one ethylenically unsaturated double bond, in the presence of such a catalyst. The preferred phosphinite ligand has the following formula (Ia), wherein R and R , independent of one another, represent hydrogen or trifluoromethyl.

Abstract: FIELD: industrial organic synthesis. SUBSTANCE: 1,3-butadiene interacts with alcohol of formula ROH, wherein R is alkyl or alkenyl with 2-20 carbon atoms optionally substituted by one or two C 1 -C 10 -alkoxy or hydroxy-C 1 -C 10 -alkoxy groups; C 6 -C 10 -aryl; C 7 -C 11 -arylalkyl; or methyl at elevated temperatures and pressure in presence of Broensted acid or Ib, VIIb or VIIIb group element complex with phosphorus- or nitrogen-containing ligands to form adducts corresponding to structures C-C=C-C-OR (II) and C-C(OR)-C=C (III). Adduct III is isomerized into adduct II. The latter is subjected to isomerization in presence of transition metal-containing homogeneous or heterogeneous catalyst in liquid phase or in presence of transition metal-containing heterogeneous catalyst in gas phase to form enol ether with structure C-C- C=C-OR (IV). Enol ether IV is subjected to action of hydrogen and water or only water in presence of homogeneous or heterogeneous catalyst as indicated above to form n-butyraldehyde and/or n-butanol, from which alcohol ROH is further released and recycled into the first step of process. EFFECT: increased selectivity of process and yield of products. 7 cl, 1 dwg, 6 tbl, 15 ex
