摘要： The invention relates to a continuous method for the catalytic hydrogenation of an aromatic compound into a cycloaliphatic compound, wherein said method is carried out in a piston reactor provided with a mechanical axially agitating means and comprises continuously feeding a liquid phase comprising said aromatic compound and a catalyst dispersed in the liquid phase, subjecting said liquid phase, at a temperature of between 100°C and 300°C and while being mechanically axially agitated, to the effects of a hydrogen pressure of between 10 and 250 bars in the presence of said catalyst dispersed in the liquid phase for a residence time t of between 1 second and 10 minutes, and removing the liquid phase from the reactor.

摘要： The invention relates to a continuous method for the carbonylation of an (R
1 R
3 )C - X alcohol in acid, where: R
1 and R
3 are radicals bonded to the carbon atom by means of a single covalent bond, or an aliphatic cyclic compound that integrates the central carbon atom and bonds to the latter on each side by means of a single covalent bond; and C - X is C(R) - OH, where R is (Z
1 Z
2 )HC- or (Z
1 Z
2 )C-, it being a given that said radical (Z
1 Z
2 )C- can be a substituted or unsubstituted unsaturated cyclic compound such as a benzene cyclic compound. Said method is carried out in a piston reactor provided with a mechanical axial agitation means, and in said method: a) at least one liquid phase comprising said raw alcohol is continuously added, optionally into an appropriate solvent, and a strong acid is also continuously added; b) said at least one liquid phase is subjected to mechanically axially agitated under the influence of a CO pressure of 2 to 250 bar during a transit time t of between 10 seconds and 10 minutes; and c) the liquid phase is removed from said reactor, and in said method, the temperature increase ΔT of the liquid, between the input thereof and removal thereof in/from the reactor, is controlled such that the ratio ΔΤ/AT
ad (where AT
ad is the adiabatic temperature increase) is between 0.02 and 0.6 when the ratio between the characteristic heat transfer time t
therm and the characteristic matter transfer time t
mat is between 1 and 50.
