Latest Patents
One of Ryouichi Tamai's latest patents concerns a novel method for producing 1,1,1,3,3-pentafluoropropane. This invention outlines two main processes: a liquid phase fluorination of 1-chloro-3,3,3-trifluoropropene using hydrogen fluoride in the presence of an antimony compound catalyst, and a gas phase fluorination utilizing a fluorination catalyst. The first method yields high quantities of the desired product, while the second enables continuous production, making it advantageous for large-scale industrial applications.
Additionally, his invention details a method involving a two-step process where hydrogen fluoride is added to 1-chloro-3,3,3-trifluoropropene in the presence of an addition catalyst, resulting in 1,1,1,3-tetrafluoro-3-chloropropane. This compound can subsequently be disproportionated into 1,1,1,3,3-pentafluoropropane and 1,1,1-trifluoro-3,3-dichloropropane with high selectivity and yield. The capability to produce 1-chloro-3,3,3-trifluoropropene effectively enhances the overall production process.
