Abstract: A process for performing a heterogeneously catalysed reaction for the oxidative esterification of aldehydes to carboxylic esters can be performed. Against this background, the process has made it possible to keep the heterogeneous, precious metal catalyst used in this method active during operation in a particularly effective manner, in order to lengthen the period between downtimes and to effect particularly sustainable catalyst management. This gives rise to the possibility of performing such processes in a very simple, economically viable and environmentally benign manner.

A ferrite is loaded on the pore surface of the porous aluminum nitride matrix; and nano nickel particles are loaded on the surface of the ferrite. The preparation method of the aluminum nitride ceramic comprises steps: sintering the aluminum nitride ceramic by pressureless sintering method, depositing the ferrite on pore surface of porous aluminum nitride matrix by hydrothermal method, and loading nano nickel particles on the surface of the ferrite by reduction method. A micro-reactor is provided. So that the technical problems: the preheating time of the micro-reactor prepared is too long, nickel particles fall off from the surface of matrix, and nano nickel particles grow up due to quick and direct temperature rise can be solved.
