Title: Scott A VanDiest: Innovator in Surfactant Technology

Introduction

Scott A VanDiest is a notable inventor based in Cincinnati, OH (US). He has made significant contributions to the field of surfactant technology, holding 2 patents that showcase his innovative approach to chemical processes.

Latest Patents

One of his latest patents is titled "Process for preparing N-alkyl polyhydroxyalkyl amines in aqueous/hydroxy." In this patent, amines such as methyl amine are reacted with materials like reducing sugars in aqueous/hydroxy solvents, including water and/or methanol, to prepare N-alkyl polyhydroxy amines. For instance, glucose is reacted with methyl amine, and the resulting adduct is hydrogenated to yield N-methylglucamine. This process allows for the creation of detersive surfactants from non-petrochemical precursors, such as sugars and fatty acid esters derived from various fats and oils.

Another significant patent by VanDiest is "Regeneration of copper chromite hydrogenation catalyst." This invention involves regenerating spent copper chromite catalyst from the hydrogenation of carboxylic acids or esters. The catalyst is treated under vacuum at high temperatures to reduce organic residue levels to less than about 25%, followed by oxidation.
