Title: The Innovations of Andreas Böttcher
Introduction
Andreas Böttcher is a notable inventor based in Nussloch, Germany. He has made significant contributions to the field of chemistry, particularly in the production of L-ascorbic acid. With a total of 4 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method for the production of L-ascorbic acid by lactonization of 2-keto-L-gulonic acid or s2-keto-L-gulonate esters. This invention relates to a process for the preparation of L-ascorbic acid, in which free 2-keto-L-gulonic acid or C-C-alkyl 2-keto-L-gulonate is lactonized under acidic conditions in the presence of a water-miscible solvent. The solvent in situ forms a medium in which the ascorbic acid formed is poorly soluble. Another significant patent is for the preparation of 2-keto-L-gulonic esters. In this process, C-C-alkyl 2-keto-L-gulonates are prepared by esterifying 2-keto-L-gulonic acid or diacetone-2-keto-L-gulonic acid with a C-C-alcohol in the presence of an acidic catalyst. The esterification is carried out in a liquid film on a hot surface with simultaneous removal of water.
