Title: Wilhelm Riemenschneider: Innovator in Chemical Processes
Introduction
Wilhelm Riemenschneider is a notable inventor based in Frankfurt-am-Main, Germany. He has made significant contributions to the field of chemical processes, holding a total of 7 patents. His work focuses on innovative methods for the preparation of various chemical compounds.
Latest Patents
Riemenschneider's latest patents include a process for the preparation of beta-hydroxypolyamines. This process involves the reaction of polyepoxide compounds with ammonia, where at least one polyepoxide compound is treated in a first stage with liquid ammonia at temperatures below 50°C. A homogeneous phase is formed, after which the reaction between the polyepoxide compound and ammonia is carried out in a second stage at temperatures ranging from 60°C to 130°C. Once the reaction is complete, the excess ammonia is removed from the reaction mixture. The resulting beta-hydroxypolyamines are utilized as binders, which can be diluted with water, either alone or in combination with suitable crosslinking agents. Another significant patent involves a continuous process for the production of chloroalkyl-sulfonyl isocyanates. This invention relates to a catalytically induced reaction of chlorosulfonyl isocyanate with one or more C2-C4 olefins, conducted in a continuous manner within a tubular reactor.
