Title: The Innovative Contributions of Robert A. Meyer

Introduction

Robert A. Meyer is a notable inventor based in Ballwin, MO (US), recognized for his significant contributions to the field of chemical engineering. With a total of 18 patents to his name, Meyer has made substantial advancements in the recovery of valuable materials from chemical processes. His work exemplifies the intersection of innovation and practical application in industrial chemistry.

Latest Patents

One of Robert A. Meyer's latest patents focuses on a process for the recovery of molybdenum from residual fractions derived from an epoxidation reaction of propylene. This innovative method involves using tertiary butyl hydroperoxide in a liquid phase with tertiary butyl alcohol, in the presence of soluble molybdenum. The process includes several steps: fractionating the epoxidation reaction product to obtain a liquid fraction containing molybdenum, contacting this liquid fraction with anhydrous ammonia to form a precipitate, and separating the liquid phase from the solid. Additionally, the liquid phase is evaporated under specific conditions to separate it into a vapor free of molybdenum and a concentrate containing the molybdenum. The concentrate is then rapidly cooled to convert it into a brittle, fracturable solid, facilitating environmentally acceptable disposal.
