Title: Walter Disteldorf: Innovator in Carboxylic Acid Ester Production

Introduction

Walter Disteldorf is a notable inventor based in Wachenheim, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of carboxylic acid esters. With a total of 14 patents to his name, Disteldorf's work has had a considerable impact on industrial processes.

Latest Patents

One of his latest patents is a method for producing carboxylic acid esters. This invention involves converting a carboxylic acid or a carboxylic acid anhydride, or a mixture thereof, with an alcohol in a reaction system comprising one or more reactors. The method includes distilling reaction water as an alcohol-water-azeotrope with the vapors. The vapors are at least partially condensed, and the condensate is separated into an aqueous phase and an organic phase. The organic phase is then supplied back into the reaction system. Components boiling lower than the alcohol are at least partially removed from the returned organic phase, ensuring that an enrichment of by-products boiling lower than alcohol is avoided. This innovative approach minimizes alcohol losses through discharge currents.
