    Abstract: The invention relates to a method for producing vinyl phosphonic acid compounds of general formula (I) wherein R1 and R2 are independently H, C1-16-aryl, C7-12-alkaryl or C7-12-aralkyl radicals, wherein the organic radicals can be substituted by one or several halogen atoms, hydroxyl, acyl or acetoxy groups. Production occurs by reacting phosphoric acid compounds of general formula (II) with acetylene in the presence of a Pd(II) complex and/or a Pd(0) complex or corresponding Pt complexes as a catalyst.

    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: In a process for hydrogenating unsubstituted monocyclic or polycyclic aromatics or monocyclic or polycyclic aromatics substituted by at least one alkyl group, amino group or hydroxyl group or a combination of two or more thereof to form the corresponding cycloaliphatics by means of gaseous hydrogen in the presence of at least one catalyst in a reaction column (4) in which the reactants are passed over the catalyst(s) (5) fixed in the reaction column (4), the cycloaliphatics are taken off at a side offtake (14) or from the bottom of the column (6) through a line (8) or at the side offtake (14) and from the bottom of the column (6) through a line (8).
