Title: Innovations of Dennis G VanKoevering
Introduction
Dennis G VanKoevering is a notable inventor based in Midland, MI (US). He has made significant contributions to the field of chemical engineering, particularly in the development of processes involving polydiorganosiloxanes. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is titled "Anhydrous hydrogen chloride evolving one-step process for producing." This invention describes a one-step process for producing polydiorganosiloxanes. In this process, a mixture comprising diorganodichlorosilane and a source of triorganosilyl groups is contacted with excess water that is essentially saturated with hydrogen chloride. The product siloxanes are isolated along with saturated aqueous hydrogen chloride and anhydrous hydrogen chloride. The amount of triorganosilyl groups present in the mixture is controlled to set the degree of polymerization of the product siloxanes. Additionally, the isolated saturated aqueous hydrogen chloride is recycled to the process, while excess chloride generated is collected as anhydrous hydrogen chloride.
Another significant patent by VanKoevering is for a "Catalyzed redistribution of polyorganosiloxanes." This invention outlines a catalyzed process for the redistribution of linear, chloride or hydroxy end-terminated polyorganosiloxanes or cyclic polyorganosiloxanes. Effective catalysts for this process include alumina, silica-alumina, activated carbon, zeolite, and acid clay. The catalyzed redistribution process can be incorporated as an element of a three-stage process, allowing for control of the yield of cyclic polyorganosiloxanes.
