Title: Melville E Hillman: Innovator in Cyclic Ester Production
Introduction
Melville E Hillman is a notable inventor based in Hilliard, OH (US). He has made significant contributions to the field of chemical engineering, particularly in the production of cyclic esters. With a total of 3 patents to his name, Hillman's work showcases his innovative approach to solving complex problems in chemical processes.
Latest Patents
One of Hillman's latest patents is a method to produce cyclic esters. This novel integrated process involves the recovery of starting materials, such as lactic acid, from a dilute aqueous lactic acid-containing solution through solvent extraction. The starting materials are then transformed into cyclic esters by removing water while maintaining the concentration of higher molecular weight oligomers below about 20 wt % of the reaction composition. The process also includes providing a recovery solvent for the reaction composition and separating the cyclic esters from the starting materials and higher molecular weight oligomers using liquid-liquid equilibrium separation. This invention emphasizes the efficient production and recovery of cyclic esters by integrating various unit operations with appropriate solvents and recycle streams. Additionally, it achieves high rates of conversion of starting materials and selective production of cyclic esters through careful control of process parameters.
