Title: Johann Stamm: Innovator in Vinyl Acetate Processes

Introduction

Johann Stamm is a notable inventor based in Frankfurt-am-Main, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of vinyl acetate. With a total of three patents to his name, Stamm's work has had a considerable impact on the industry.

Latest Patents

Stamm's latest patents include a process for isolating vinyl acetate and a process for preparing vinyl acetate. The first patent describes a method for isolating vinyl acetate from the gas mixture formed in the reaction of ethylene with acetic acid and oxygen over catalysts comprising palladium or palladium compounds. This process involves the recirculation of the acetic-acid solution obtained in the circulating gas scrubber to the first distillation column, known as the predewatering column. The second patent outlines a method of saturating ethylene-containing gases with acetic acid before they are fed into a vinyl acetate reactor. In this method, the acetic acid recovered in the vinyl acetate process is introduced into a column with a countercurrent stripping section and a rectification section. Ethylene-containing gas is supplied from the bottom, and the liquid taken off at the bottom is divided into two substreams, with one substream pumped back into the column to maintain sufficient saturation with acetic acid.
