Title: The Innovative Contributions of Rangasamy Pitchai

Introduction

Rangasamy Pitchai, an accomplished inventor based in West Chester, Pennsylvania, has made significant contributions to the field of chemical engineering. With a remarkable portfolio of 17 patents, he has developed innovative processes that enhance the efficiency and selectivity of chemical reactions.

Latest Patents

Among his latest inventions is the patent for an aqueous epoxidation process using modified titanium zeolite. This process involves epoxidizing an olefin with hydrogen peroxide in the presence of a specially modified titanium zeolite catalyst. The modification with platinum, palladium, or copper compounds has been found to unexpectedly increase olefin epoxidation activity, making the process more effective.

Another notable patent is related to the use of alkaline earth metal compound-supported silver catalysts. In this invention, propylene is oxidized to propylene oxide in the vapor phase using an oxygen-containing gas. The supported silver catalyst, primarily made from alkaline earth metal compounds such as calcium titanate or strontium titanate, demonstrates significantly higher selectivity to the desired epoxide than would normally be expected. The introduction of nitrogen oxide species, alkyl halides, and carbon dioxide into the oxygen-containing gas further enhances the selectivity for propylene oxide.
