Successful applications of the chemical microprocess technology in the field of screening and the synthesis of fine chemicals using also new preparation routes are presented. By means of these examples it is shown that the microprocess technology allows new screening methods for the preparation of compound libraries or the investigation of catalysts, breaks new ground for the preparation of fine chemicals and offer novel possibilities for the production of chemicals on an industrial-scale.
