Abstract: Monophosphites including a benzopinacol structure and metal complexes thereof are provided. The metal complex compositions are useful as hydroformylation catalysts. The metals of the complex include Rh, Ru, Co and Ir. A method of hydroformylation using the metal complex or the metal complex components is also provided.

Abstract: Monophosphites comprising an anthrol are useful for catalyzing hydroformylation of an olefin to an aldehyde.

Abstract: An OCTOL process is disclosed which by limitation of the conversion in its individual oligomerization steps is set up particularly for the productive utilization of C4 feedstock mixtures with a low 1-butene content and which nevertheless yields a C8 product mixture having an Iso index suitable for the preparation of plasticizer alcohols.

Abstract: The invention relates to a method for the thioetherification of mercaptanes with polyunsaturated hydrocarbons, carried out in a reactor with the addition of hydrogen, using a heterogenic catalyst and in the presence of 1-butene. The aim of the invention is to develop such a method to the extent that the creation of value from the C4 raw material stream is increased. Said aim is achieved in that the hydrogen is added to the reaction in such a manner that the molar ratio of hydrogen to polyunsaturated hydrocarbons is no more than one.

Abstract: A mixture containing a monophosphite ligand is useful for the catalysis of a hydroformylation reaction.

Abstract: A novel monophosphite ligand having a tert-butyloxycarbonyl group is useful as a ligand in hydroformylation of an olefin.

Abstract: A mixture containing a monophosphite ligand is useful for the catalysis of a hydroformylation reaction.

Abstract: The catalytic preparation of an aldehyde from an olefin proceeds in the presence of a monophosphite mixture.

Abstract: The preparation of high-quality oxo process alcohols from inconstant raw material sources is the technically demanding problem which is addressed by a process for continuously preparing an alcohol mixture, in which an input mixture which contains an olefin and has a composition that changes over time is subjected to an oligomerization to obtain an oligomerizate and at least a portion of the olefin oligomers present in the oligomerizate are hydroformylated with carbon monoxide and hydrogen in a hydroformylation in the presence of a homogeneous catalyst system to give aldehydes, at least some of which are converted to the alcohol mixture by subsequent hydrogenation. The process provides a constant plasticizer quality to be produced over a long production period and, optionally, a higher throughput with the same product quality.

Abstract: A novel monophosphite ligand having a tert-butyloxycarbonyl group is useful as a ligand in hydroformylation of an olefin.

Abstract: The process described here has made it possible to obtain boron-containing silicates having a zeolitic structure which display negligible DME and C8 selectivities combined with high activities when used as catalysts for the dissociation of MTBE.
