Fluoroalkyl alkyl carbonates and fluorosubstituted carbamates which are suitable as additives or solvents in lithium ion batteries are prepared from fluoroalkyl fluoroformates and the respective alcohol or amine. Methanol is the preferred alcohol, dimethylamine and diethylamine are preferred amines. Fluoromethyl methyl carbonate is the preferred compound to be produced. Fluoroalkyl fluoroformates can be prepared from aldehydes and carbonyl fluoride.


The presence of certain impurities in diphenyl sulfone have a deleterious effect on the properties of the poly(aryletherketone)s produced therein, including one or more of color, melt stability, molecular weight, crystallinity, etc. and here identify those impurities and provide processes for the recovery of the diphenyl sulfone.

In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided undercut, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.
