Latest Patents

Hongping Li holds a patent for a "Separation and recovery method for boron trifluoride and complex thereof in olefin polymerization reaction." This invention provides a method for the separation and recovery of boron trifluoride and its complexes during the olefin polymerization process. The method involves several steps: first, a mixture obtained after the olefin polymerization reaction is subjected to flash distillation separation to isolate part of the gaseous boron trifluoride. Next, the liquid phase from this separation undergoes membrane separation to obtain complexes of boron trifluoride along with a crude product of the olefin polymerization reaction. Finally, the crude product is treated with gas stripping separation to extract the remaining gaseous boron trifluoride, resulting in a pure product of the olefin polymerization reaction. This innovative process is designed to achieve efficient separation based on the polymorphic characteristics of boron trifluoride and its complexes.
