Title: Franz Merger: Innovating in Chemical Processes and Compositions
Introduction:
Franz Merger is a renowned inventor hailing from Frankenthal, Germany, who has made significant contributions to the field of chemical processes and compositions. With an extensive portfolio of 150 patents, his expertise lies in catalytic hydrogenation and the development of polyisocyanate compositions. This article will delve into his latest patents, career highlights, collaborations, and provide a comprehensive overview of his remarkable innovations.
Latest Patents:
Franz Merger recently showcased his ingenuity in his two groundbreaking patents:
1. Preparation of alcohols: Merger's patent focuses on a novel method for preparing alcohols. By catalytic hydrogenation of corresponding carbonyl compounds in the liquid phase, using a catalyst that contains copper on an SiO2-containing carrier with or without the presence of elements like magnesium, barium, zinc, and chromium, Merger has revolutionized the process. This innovation enables the production of alcohols more efficiently at elevated temperatures and superatmospheric pressure.
2. Polyisocyanate compositions with a long shelf life: Merger's patent addresses the development of polyisocyanate compositions that possess an extended shelf life. Employing phosgene-free methods, particularly by thermal cleavage of (cyclo)aliphatic polycarbamates, Merger has formulated stable polyisocyanate compositions. Furthermore, he incorporates primary stabilizers (such as sterically hindered phenols and/or aromatic amines), secondary stabilizers (such as organic phosphites and/or thioethers), or acidic stabilizers (including carboxylic acids, acyl chlorides, inorganic acids, inorganic acid chlorides, and diesters of phosphoric acid) for enhanced stability.
