Title: Wilfried Krix: Innovator in Phthalic Anhydride Production
Introduction
Wilfried Krix is a notable inventor based in Bottrop, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of phthalic anhydride. With a total of 2 patents to his name, Krix has developed innovative processes that enhance the efficiency and effectiveness of chemical manufacturing.
Latest Patents
Krix's latest patents include a method for the manufacture of phthalic anhydride by gas phase oxidation of a mixture of o-xylol and naphthalene. This process involves producing a solution of 1 to 80 parts by mass naphthalene in 99 to 20 parts by mass o-xylol at temperatures ranging from 0 to 80 degrees Celsius. The solution is stored at this temperature and heated shortly before the reaction to 110 to 180 degrees Celsius. The heated solution is then atomized into a hot airflow, passed over metal oxide catalysts in the gas phase, and the phthalic anhydride product is collected. This innovative approach allows for a problem-free manufacture of phthalic anhydride. Another patent focuses on utilizing distillation residues of phthalic anhydride or maleic anhydride, which includes cooling hot, liquid distillation residues while flowing in a first organic liquid, comminuting the solidified residues, suspending the granulate in a second organic liquid, and incinerating the suspension or converting it into synthesis gas.
