Title: Kermit D Longley: Innovator in Chemical Engineering

Introduction

Kermit D Longley is a notable inventor based in Park Forest, IL (US), recognized for his contributions to chemical engineering. He holds a total of seven patents, showcasing his innovative spirit and expertise in the field.

Latest Patents

Among his latest patents is the development of aromatic base poly-sulfosuccinate esters. This invention involves di- and other poly-sulfosuccinate esters of di- and other poly-hydroxyl aromatic propoxylated compounds. The process includes etherifying hydroxyl groups of bisphenol, such as Bisphenol A, with propylene oxide. The resulting propoxylated bisphenol is then esterified with maleic anhydride, leading to the creation of di- and/or poly-maleic acid esters. These esters possess free carboxyl groups that are further esterified with propylene oxide. The final compound is treated to introduce sulfosuccinated groups, making these novel di- and poly-sulfosuccinates particularly useful as surfactants in emulsion polymerization processes for various applications, including upholstery and carpet backings.

Another significant patent involves a method for the preparation of isethionic acid. This method treats an alkali metal isethionate with hydrochloric acid to yield isethionic acid and a chloride salt. The chloride salt is removed to provide a concentrated aqueous solution of isethionic acid, which can be further reacted with polyvalent metal oxides, hydroxides, or amines to form heavy metal isethionates. For instance, zinc isethionate serves as a catalyst in the production of acyl isethionates used in soap bars.
