    摘要: Olefins having from 5 to 24, in particular from 5 to 12, carbon atoms are hydroformylated by reacting an olefin or a mixture of olefins in the presence of an unmodified cobalt catalyst in a single-stage process in a reactor at a temperature of from 100° C. to 220° C. and a pressure of from 100 bar to 400 bar, to obtain an aldehyde, an alcohol or a mixture thereof. An aqueous bottom phase and an organic phase are present in the reactor, the aqueous bottom phase is mixed with the organic phase, and a concentration of the cobalt catalyst, calculated as metallic cobalt, in the aqueous bottom phase is in the range from 0.4 to 1.7% by mass based on the total weight of the aqueous bottom phase. A level of the aqueous bottom phase in the reactor is kept constant during steady-state operation.

    摘要: An interpolation of data values is performed during the acquisition of a 3D image dataset which is free of traces of a metal object imaged in the underlying 2D image datasets. A target function is defined into which data values of the 3D image dataset that are dependent on said substitute data values are incorporated following preprocessing. The substitute data values are then varied iteratively until the value of the target function satisfies a predetermined criterion. Residual artifacts that still persist following the interpolation can thus be effectively reduced.
