Title: Innovations of Rajesh Popatlal Pandya in Eco-Friendly Chemistry.
Introduction
Rajesh Popatlal Pandya is a notable inventor based in Gujarat, India. He has made significant contributions to the field of eco-friendly chemical processes. His innovative approach focuses on reducing environmental impact while maintaining high product purity.
Latest Patents
Rajesh Popatlal Pandya holds a patent for an eco-friendly method of preparation of high purity tetrabromobisphenol-A. This method produces a highly pure and colorless tetrabromobisphenol-A (TBBPA) with a melting point in the range of 178-182°C. The process achieves yields of 50-70% in the first batch and 90-100% when the spent organic layer is recycled. By using sodium bromide and hydrobromic acid as brominating agents, he effectively displaces corrosive liquid bromine. Additionally, sodium bromate serves as both an oxidizing and brominating agent, utilizing the hydrobromic acid produced during the bromination of bisphenol-A (BPA). The reaction occurs at 10-15°C in a mixture of methylene chloride-water or carbon tetrachloride-water, with hydrochloric acid and sodium lauryl sulfate present. The crystalline product is filtered, washed, dried, and weighed, while the spent organic layer is recycled to maximize yield and minimize organic effluent generation.
