Latest Patents
Among Kalidas Paul's latest patents, the "Process for preparing hexachlorocyclopentadiene" stands out. This patented process involves several key steps. First, liquid cyclopentadiene is reacted with chlorine at temperatures ranging from approximately 0°C to 100°C. This reaction continues until an average of four chlorine atoms is added per mole of cyclopentadiene, resulting in a first-stage product. The process advances to a second stage, where the first-stage product is heated to temperatures between 140°C and 200°C with the introduction of chlorine and an aromatic compound. This stage aims to increase the chlorine content of the resultant chemicals to an average of six chlorine atoms per molecule. Finally, in the third stage, the products are vaporized and heated to temperatures exceeding 450°C, facilitating the conversion of these products into hexachlorocyclopentadiene.
