Title: Innovations by David J Anneken
Introduction
David J Anneken is an accomplished inventor based in Cincinnati, OH (US). He holds a total of 2 patents that showcase his contributions to the field of chemical engineering. His work primarily focuses on improving the properties of various chemical compounds.
Latest Patents
One of his latest patents is titled "Process for improving color and color stability of oleic acid." This invention describes a method for enhancing the color and color stability of oleic acid through a two-column distillation process. In this process, oleic acid is introduced into a first distillation zone, which contains both an enriching section and a stripping section. This setup allows for the production of a minor amount of a topping product and a major amount of underflow containing the oleic acid. The oleic acid is then passed to the bottom portion of a second distillation zone, where it is further processed to recover the improved oleic acid as a top product with enhanced color and stability.
Another significant patent by Anneken is the "Method of making hydrogenated acids." This invention involves hydrogenating a mixture of saturated and unsaturated carboxylic acids using an effective amount of a hydrogenation catalyst. The process is conducted in the presence of an adsorbent, resulting in a hydrogenated product that contains less than about 200 ppm of oxygenated by-products and an iodine value of less than 10.
