| A composition is provided as a salt having the formula MBF3X where M is an alkali metal cation and X is the halide fluoride, bromide or iodide. A lithium salt has several characteristics making the composition well suited for inclusion within a lithium-ion battery. A process for forming an alkali metal trifluorohaloborate salt includes the preparation of a boron trifluoride etherate in an organic solvent. An alkali metal halide salt where the halide is chloride, bromide or iodide is suspended in the solution and reacted with boron trifluoride etherate to form an alkali metal trifluorohaloborate. The alkali metal trifluorohaloborate so produced is collected as a solid from the solution. The process is simple and yields alkali metal trifluorohaloborate of sufficient purity to be used directly in battery applications. | ||||||

| The invention is directed to the fumigation of soils, enclosed spaces, agricultural products and other commodities, etc., using compositions which decompose to form carbon disulfide and certain other biocidal materials. Such fumigation can be used to control bacteria, fungi, insects, nematodes, rodents, nitrification, and weeds.Fumigant compositions are described herein as "thiocarbonates," including, without limitation, salts of trithiocarbonic acid and tetrathiocarbonic acid, compositions having empirical formulae intermediate to these acids salts (such as MCS.sub.3.7, wherein M is a divalent metal ion), and compositions containing substances in addition to thiocarbonates, such as a stabilized ammonium tetrathiocarbonate which contains ammonium sulfide, i.e., (NH.sub.4).sub.2 CS.sub.4 (NH.sub.4).sub.2 S.The compositions are generally water soluble and can be prepared, stored, and used in aqueous solutions. Thiocarbonate solutions of the invention are stable during prolonged periods of storage in a closed container, exhibit a low vapor pressure, and are not flammable. For soil fumigation, thiocarbonates can be mixed with fertilizers to provide a multi-functional application. | ||||||

| 128 | Method of removing heavy metal from wastewater streams | US843109 | 1986-03-24 | US4678584A | 1987-07-07 | Geraldine S. Elfline |
| A method for treating a heavy metal-containing liquid, such as a wastewater stream, oil for recycling, or other metal-bearing liquid, with a trithiocarbonate, particularly an alkali metal trithiocarbonate, such as sodium trithiocarbonate, to precipitate the metals as insoluble sulfides. The precipitated metal sulfides are recovered as a low volume sludge, which can be processed through standard metallurgical techniques to yield the metals in economically useful forms. Among the most unexpected results produced by this method is the lowering of the selenium content in a naturally occurring body of water from 1.0 ppm to 0.0015 ppm. | ||||||
