Title: The Innovative Contributions of Mario Pitzalis
Introduction
Mario Pitzalis is a notable inventor based in Arcore, Milan, Italy. He has made significant contributions to the field of epoxy resins, holding three patents that showcase his innovative approach to resin preparation. His work has implications for various applications requiring high-performance materials.
Latest Patents
One of his latest patents involves the preparation of novolak epoxy resins. This process includes adding an aqueous solution of alkali metal hydroxide to a solution of Novolak phenolic resin in epichlorohydrin. During this addition, water is distilled off in the form of an azeotrope with epichlorohydrin, which is then recycled. The reaction is maintained at a temperature of 60-80 degrees Celsius and a pH between 7 and 8, with a water content of 0.5 to 2.5 wt.% in the medium. The resulting thermosetting resin is suitable for applications that require low chlorine contents, low viscosity, and high epoxy value.
Another significant patent by Pitzalis focuses on the preparation of liquid epoxy resins from bisphenols. This method involves gradually feeding an aqueous solution of alkali metal hydroxide into a solution of bisphenol-A in epichlorohydrin. The reaction medium is kept at boiling point, with water distilled off as an azeotrope with epichlorohydrin and recycled. The water content is maintained between 0.1 to 0.7 wt.% and a pH value between 7 and 9. The resulting liquid epoxy resins exhibit low viscosity, epoxy equivalent, and hydrolyzable chlorine content.
