    摘要: Processes for preparing a C5 aldehyde and propene are disclosed, the processes comprising: (a) providing a feedstream, the feedstream comprising butane, 1-butene, 2-butene and 1,3-butadiene, the 1,3-butadiene present in the feedstream in an amount up to 1000 ppm; (b) contacting the feedstream with hydrogen and carbon monoxide in the presence of a hydroformylation catalsyt to form a 2-butene-rich butane stream and a C5 aldehyde; (c) separating the 2-butene-rich butane stream and the C5 aldehyde; and (d) contacting the 2-butene-rich butane stream with ethene in the presence of a metathesis catalyst to form a propene-containing hydrocarbon stream.

    摘要: Process for preparing tricyclodecanedialdehyde by hydroformylation of dicyclopentadiene by means of a CO/H2 mixture at elevated temperature and under superatmospheric pressure in the presence of a rhodium catalyst which has not been modified by means of a ligand and is homogeneously dissolved in the hydroformylation medium, wherein the hydroformylation is carried out at a pressure of from 200 to 350 bar in at least two reaction zones, with a reaction temperature of from 80 to 120° C. being set in a first reaction zone and a reaction temperature of from 120 to 150° C. being set in a reaction zone following this reaction zone, with the proviso that the reaction temperature in the subsequent reaction zone is at least 5° C. higher than in the preceding reaction zone.
