Title: Werner Hagen - Innovator in Carboxylic Acid Recovery
Introduction
Werner Hagen is a notable inventor based in Heidelberg, Germany. He has made significant contributions to the field of chemical engineering, particularly in the recovery of carboxylic acids from oxo residues. His innovative approach has implications for both industrial processes and environmental sustainability.
Latest Patents
Hagen holds a patent for a process titled "Recovery of carboxylic acids from oxo residues." This patent describes a method for isolating carboxylic acids from residues generated during the hydroformylation of ethylene or propylene. The process involves several steps, including the removal of aldehydes, hydrogenation, treatment with aqueous alkali metal hydroxide solutions, and distillation. The acidification of the residues with strong mineral acids to a pH of 2-4 is crucial, ensuring that the acidified mixture contains no more than 5 parts by weight of water per part by weight of the carboxylic acids. The organic phase is then separated, allowing for the isolation of carboxylic acids through distillation at pressures below 150 mbar. The resulting carboxylic acids can be utilized as solvents or in the manufacture of esters.
