Title: Innovations of Thomas C Singleton

Introduction

Thomas C Singleton is a notable inventor based in Texas City, TX, with a remarkable portfolio of seven patents. His work primarily focuses on advancements in chemical processes, particularly in carbonylation techniques.

Latest Patents

Singleton's latest patents include a carbonylation process utilizing an alkali metal acetate as a catalyst stabilizer. This invention enhances the reaction of olefins, alcohols, or their derivatives with carbon monoxide in a liquid phase. The process involves a catalyst system containing a rhodium component and an iodine or bromine component. By transferring a portion of the liquid reaction mass to a separation zone with lower CO partial pressure, the system allows for the vaporization and withdrawal of carbonylation products, unreacted carbon monoxide, inert gases, and unreacted olefins or alcohols. Additionally, precipitation of the rhodium catalyst is mitigated by introducing a catalyst stabilizer, which can be a germanium (IV) compound or an alkali metal compound.

Another significant patent by Singleton is a process for stabilizing carbonylation catalysts in soluble form. This invention also involves the reaction of olefins, alcohols, or their derivatives with carbon monoxide in a liquid phase. The catalyst system remains similar, with the addition of stabilizers such as N,N,N',N'-tetramethyl-o-phenylenediamine and 2,3'-dipyridyl to prevent catalyst precipitation under carbon monoxide deficient conditions.
