Title: The Innovative Contributions of David G Braithwaite

Introduction

David G Braithwaite is a notable inventor based in Brookhaven, MS (US), recognized for his significant contributions to the field of chemical engineering. With a total of 15 patents to his name, he has made remarkable advancements in the production of fuel-grade alcohols and acrylamide.

Latest Patents

Among his latest patents is the "Extractive distillation process for the production of fuel grade alcohols." This innovative process involves a novel composition and extraction method for dehydrating a hydrated aliphatic, monohydric alcohol to yield fuel-grade alcohol. The process utilizes a select group of alkali-metal and alkaline-earth metal salts dissolved in a low volatility polyhydric alcohol, which acts as a solvent extractant. This extractant is then contacted with the hydrated alcohol, distilled, condensed, and ultimately recovers a dehydrated fuel-grade alcohol. Another significant patent is for "Solvents for the catalytic production of acrylamide from acrylonitrile." This method catalytically converts acrylonitrile and water using a metallic conversion catalyst to produce pure acrylamide crystals.
