Title: The Inventive Journey of J Douglas Mansell

Introduction

J Douglas Mansell, an accomplished inventor based in Sulphur, Louisiana, has made significant contributions to the field of chemical engineering with a total of nine patents to his name. His work primarily focuses on chemical processes that enhance the production and purification of important industrial compounds.

Latest Patents

Among Mansell's latest innovations are two notable patents. The first patent involves the "Concurrent production of trichloroethane isomers." In this invention, both 1,1,1-trichloroethane (also known as methylchloroform) and 1,1,2-trichloroethane are synthesized simultaneously within the same reactor. This is achieved by introducing molecular chlorine and chloroethene, along with 1,1-dichloroethane, into the reactor, allowing for precise control over the ratios of the two isomers produced. The reaction takes place in the liquid phase with a free radical initiator.

The second patent is for a "Method for purifying perchloroethylene containing dichlorobutadiene." This innovative process treats perchloroethylene contaminated with dichlorobutadiene using bromine in the presence of a free-radical initiator. The result is perchloroethylene that is substantially free of dichlorobutadiene, preserving the integrity of the main compound. Additionally, a bromine scavenger such as trichloroethylene can be incorporated to react with any excess bromine present.

Career Highlights

Mansell has held positions in prominent companies such as PPG Industries, Inc. and PPG Industries Ohio, Inc., where he has honed his skills in chemical processes and innovation.
