Title: The Innovations of Hans-Joachim Kiessling
Introduction
Hans-Joachim Kiessling is a notable inventor based in Hamburg, Germany. He has made significant contributions to the field of synthetic resins and polyamines. With a total of 5 patents to his name, Kiessling's work has had a lasting impact on various industrial applications.
Latest Patents
Kiessling'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 the preparation of soluble synthetic resins that are free from monomeric amines and contain NH bonds. This process entails the reaction of compounds with epoxide groups and polyamines in a homogeneous phase system, with the polyamine being used in excess. The resulting reaction product is purified through circulatory distillation, yielding synthetic resins that serve as self-crosslinking binders.
