Latest Patents

Lefrancois's latest patents include a method for recovering alkali metal fluorides from organic slurry. This innovative method involves adding water to a slurry containing an organic ether liquid phase and a finely-divided solid phase of alkali metal fluoride. The water is added in a precise amount to reduce the adherence of the organic ether to the solid phase without creating a separate aqueous phase. The slurry is then maintained at a treatment temperature of at least 50°C for a specified period, allowing for the separation of a crude fluoride solid and an ether liquid suitable for recycling.

Another significant patent involves producing silane from silicon tetrafluoride. In this process, silicon tetrafluoride is reacted with sodium hydride in a cyclic ether reaction medium. The addition of sodium aluminum hydride serves as a catalyst, enhancing the efficiency of the reaction. This method showcases Lefrancois's ability to innovate within the chemical manufacturing sector.
