Title: Ludovicus H Janssen: Inventor in Chemical Processes.
Introduction
Ludovicus H Janssen is an inventor associated with Geleen, the Netherlands. His work includes patented chemical processes for producing alkanones, alkanols, and benzaldehyde. He is credited with 3 patents.
Latest Patents
One of Janssen’s latest patents describes a process for preparing an alkanone and/or alkanol. The method oxidizes an alkane containing 3–30 carbon atoms with oxygen to form an alkyl hydroperoxide, then decomposes that hydroperoxide in the presence of a metal compound immobilized on a carrier. The carrier bears aliphatic or aromatic amine groups or sulphide groups, and the process is particularly suited to cycloalkanes.
Another patent concerns preparing benzaldehyde in the gas phase by hydrogenating a corresponding benzoic acid. The process uses a manganese-containing catalyst on an acid carrier, with the invention specifying a method for preparing the catalyst.
