    Abstract: PROBLEM TO BE SOLVED: To provide a composition which solves the problem of the commercial quality TCD-dimethylol that it is too viscous to pressure-feed and can be pressure-fed from a supplying vessel without melting it to enable the production of secondary products.
    SOLUTION: This composition contains (I) tricyclodecandimethylol and at least one polymerizable, preferably at least mono-unsaturated, compound in the weight ratio of 100:1-1:1, preferably 20:1-3:1. This composition was found possible to pressure-feed without melting it at room temperature.

    Abstract: A process for preparing cyclohexanol from benzene by: a) preparing cyclohexene by hydrogenating benzene in the presence of a catalyst, and b) preparing cyclohexanol by hydrating the cyclohexene in the presence of a catalyst, comprises: carrying out steps a) and b) in a reaction facility which has a bottom region at the lower end, a top region at the upper end, and a reaction zone between the top region and the bottom region which contains the catalyst according to steps a) and b), evaporating a portion of the benzene using the heat of reaction in the reaction zone, condensing it in the top region and returning it to the reaction zone, and withdrawing a reaction mixture containing cyclohexanol in the bottom region.

    Abstract: 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 catalyst 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.
