Title: Innovations of Fritz-Robert Kappler

Introduction

Fritz-Robert Kappler is a notable inventor based in Troisdorf, Germany. He has made significant contributions to the field of chemical engineering, particularly in the area of silane chemistry. With a total of 3 patents to his name, Kappler's work has had a considerable impact on industrial processes.

Latest Patents

Kappler's latest patents include a method for the separation of chlorosilanes from a gaseous mixture. This innovative method involves washing the gaseous mixture, which contains hydrogen and hydrogen chloride, with saturated hydrochloric acid. The resulting chlorosilane hydrolysis products can remain in the hydrochloric acid without interfering with the purifying action. The hydrolysis products are easily filtrable and can be periodically separated from the hydrochloric acid. In a preferred embodiment, the hydrochloric acid is recirculated and injected into the gas stream being washed.

Another significant patent is the method of preparing aminoalkylsilanes. This improved process involves the reaction of a chloroalkylsilane with ammonia or alkylamine at elevated temperatures or pressures. By adding the chloroalkylsilane in a less than stoichiometric ratio to the preheated ammonia or alkylamine, a higher yield of aminoalkylsilane is obtained in greater purity.
