Title: James Clarence Day: Innovator in High Purity Methacrylic Acid Production
Introduction
James Clarence Day, hailing from North Wales, PA, is a distinguished inventor known for his significant contributions in the field of chemical engineering, particularly in the production of methacrylic acid. With a total of five patents to his name, Day has pioneered innovative techniques that enhance purity and efficiency in chemical manufacturing.
Latest Patents
His most recent inventions include a process for manufacturing high purity methacrylic acid, which allows for the high-yield production of glacial methacrylic acid (HPMAA) while minimizing the decomposition of hydroxy isobutyric acid (HIBA). This advanced process yields methacrylic acid that is at least 99% pure and contains 0.05% or less water. The method strategically employs a series of successive distillation steps starting with a crude methacrylic acid stream formed through hydrolyzing acetone cyanohydrin, effectively purifying HIBA as a significant intermediate product.
In addition, Day has developed a process for preparing (meth)acrylic acid that utilizes turndown control to maintain optimal performance in distillation columns. This innovation enhances the dehydration process of aqueous (meth)acrylic acid, producing a refined (meth)acrylic acid solution.
