    摘要： There is provided an alcohol composition obtained by dimerizing an olefin feed comprising C.sub.6 -C.sub.10 linear olefins to obtain C.sub.12 -C.sub.20 olefins, followed by conversion to alcohols, such as by hydroformylation. The composition has an average number of branches ranging from 0.9 to 2.0 per molecule. The linear olefin feed preferably comprises at least 85% of C.sub.6 -C.sub.8 -olefins. The primary alcohol compositions are then converted to anionic or nonionic surfactants, preferably sulfated or oxyalkylated or both. The sulfated compositions are biodegradable and possess good cold water detergency. The process for making the dimerized primary alcohol comprises dimerizing, in the presence of a homogeneous dimerization catalyst under dimerization conditions, an olefin feed comprising C.sub.6 -C.sub.10 olefins and preferably at least 85 weight % of linear olefins based on the weight of the olefin feed, to obtain a C.sub.12 -C.sub.20 ; optionally double bond isomerizing said C.sub.12 -C.sub.20 olefins; and converting the C.sub.12 -C.sub.20 olefins to alcohols, preferably through hydroformylation. The process is preferably a one-step dimerization. The homogenous catalyst comprises a mixture of a nickel carboxylate or a nickel chelate, with an alkyl aluminum halide or an alkyl aluminum alkoxide.

    摘要： The invention provides for a method of making isoalcohols using syngas-to-alcohol catalyst and method of making it. The catalyst is a highly dispersed, alkali promoted, La stabilized, microcrystalline Cu.sub.2 O having a particle size of .ltoreq.6 nm in the presence of an alumina structural promoter, wherein on a mole % alkali free metals-only basis Cu is present in from 45 to 55%, Zn from 10 to 20%, Al from 10 to 25%, La from 5 to 15%, and wherein the alkali is from 0.01 to 0.91% K and from 3 to 6.5% Cs. The method of making it involves coprecipitation at a constant pH from a solution of soluble metal salts of copper, zinc, lanthanum and aluminum with an alkali hydroxide, washing the coprecipitate in the essential absence of CO.sub.2, drying and calcining it, then contacting it with K and Cs to form the promoted catalyst. The promoted catalyst is dried and recalcining to produce a catalyst precursor with highly dispersed CuO crystallites. The catalyst is activated in flowing hydrogen.

    摘要： The present invention relates to a process for the synthesis of "oxo" products or their derivatives consisting of hydrocarbon compounds containing carbonyl and/or hydroxyl groups, characterized in that a hydrocarbon substrate containing an unsaturation, such as an alkene, is reacted with reactants consisting of a mixture of hydrogen and carbon monoxide, the reaction taking place after bringing the substrate into contact with the neutral activated species of the mixture of reactants activated to the plasma state.In particular, the present invention relates to a process characterized in that an alkene is reacted to obtain a mixture containing the aldehyde and the alcohol resulting from the fixation on the double bond of the alkene of, respectively, a group ##STR1## or its group ##STR2## obtained by reduction, or only one of these two components by separating it from the mixture.Finally, the present invention also relates to installations comprising a plasma reactor, in particular of the point-plane corona discharge type or of the high-frequency type, with an apparatus for chilling by a fluidized bed, usable in the process.
