The present invention relates to a process comprising at least the steps (A) chemical reaction of at least one organic compound in the presence of at least one heterogeneous catalyst in a reaction mixture and (B) removal of the at least one heterogeneous catalyst by means of a magnetic filter, and also the use of a magnetic filter for separating off catalyst particles in a process for the hydrogenation of at least one organic compound.

Method of separating off magnetizable catalyst particles by means of magnetic filters

The calculation of the above balance shows that the division of stream () into the streams () and () used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream () comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.
