Title: Edward P. Frappier: Innovator in Chemical Processes and Degradable Materials
Introduction
Edward P. Frappier is a notable inventor based in Kernersville, NC (US). He has made significant contributions to the field of chemical processes and materials science, holding a total of 11 patents. His work focuses on innovative methods for producing citrate esters and developing degradable thermoplastic compositions.
Latest Patents
Frappier's latest patents include processes for producing citrate esters. These processes are designed to be economically efficient, utilizing esterification of a citric acid-containing fermentation broth that has been treated to remove cations and other impurities while retaining sugars. Additionally, he has developed methods for reacting an impure aqueous citric acid source with an alcohol, resulting in a heterogeneous mixture that separates the organic phase containing the ester from the aqueous phase with water-soluble impurities. This innovative approach avoids the energy-intensive distillation of water from the reaction medium. Another significant patent involves physically-modified degradable thermoplastic compositions, which are enhanced by citrate esters and other polycarboxylic acid esters. These novel citrate esters are effective in providing physical modifications, along with methods for preparing these degradable thermoplastic compositions.
