Title: Nils Brolund: Innovator in Hydroxyalkylamides and Ketene Dimers
Introduction
Nils Brolund is a notable inventor based in Dueren, Germany. He has made significant contributions to the field of chemical processes, particularly in the preparation of hydroxyalkylamides and long-chain ketene dimers. With a total of 2 patents to his name, Brolund's work has implications in various industrial applications.
Latest Patents
Brolund's latest patents include a process for the preparation of hydroxyalkylamides. This innovative process involves reacting alkyl ester and alkanolamine in the presence of a catalyst, resulting in a reaction mixture that contains the desired hydroxyalkylamide product along with a low boiling alcohol by-product. The process also includes steps for solidifying the hydroxyalkylamide product, neutralizing the catalyst, and recovering the final product.
Another significant patent focuses on the preparation of long-chain ketene dimers. This process is characterized by the absence of an organic solvent, where carboxylic acid chloride is introduced into a recipient of triethyl amine under controlled conditions. The meticulous adjustment of mixing rate, feed rate, and heat exchange ensures that the viscosity of the mixture remains below 250 mPa.s. The resulting ketene dimers are particularly suitable for use in paper sizing applications.
