Title: Harold Shalit: Innovator in Chemical Processes
Introduction
Harold Shalit is a notable inventor based in Bala Cynwyd, PA (US). He has made significant contributions to the field of chemical engineering, particularly in the production of hydrogen peroxide and alkylene carbonates. With a total of 4 patents to his name, Shalit continues to push the boundaries of innovation in his industry.
Latest Patents
One of Shalit’s latest patents involves a novel method for hydrogen peroxide production. In this process, hydrogen is diffused through a palladium-containing membrane into an aqueous solution that contains stabilizing ions and dissolved oxygen, resulting in the formation of hydrogen peroxide. This method also produces some water as a by-product, and the hydrogen peroxide can be identified and recovered from the aqueous solution in an identification zone.
Another significant patent focuses on the preparation of alkylene carbonates from olefins. This process entails reacting a cyclic or linear olefin, containing 2 to 15 carbon atoms, with carbon dioxide in a liquid phase. The reaction occurs at temperatures ranging from 30°C to 160°C and under pressures between 100 to about 2,000 psig, with a pH value between 4 and 8. The presence of oxygen or an oxygen-containing gas, along with a specific mixture of catalytic compounds, facilitates the recovery of the resulting cyclic alkylene carbonate ester.
