Abstract
The invention provides a method for producing electrolyte solvent, the method comprising reacting a glycol with a disilazane in the presence of a catalyst for a time and at a temperature to silylate the glycol, separating the catalyst from the silylated glycol, removing unreacted silazane; and purifying the silylated glycol.
Claims17
A continuous method for producing battery grade electrolyte solvent, the method comprising:
- a. reacting a glycol with a disilazane in the presence of a catalyst in a reactor for a time and at a temperature to silylate the glycol;
- b. separating the catalyst from the silylated glycol wherein the catalyst remains in the reactor;
- c. removing unreacted silazane;
- and
- d. purifying the silylated glycol, wherein the method is conducted without an inert atmosphere.
