Abstract
Abstract A mixture of silicon and phosphorus are reacted with halides to produce silicon tetra halide, silicon-phosphorus halides and phosphorus trihalide composition. This composition is reacted with any suitable organic or inorganic-organic compound which has an active hydrogen, halide and/or a metal radical to produce organic silicon-phosphorus halides compositions which will react with inorganic, inorganic-organic and organic compound to produce an organic silicon-phosphorus product. These products may be used as flame-retardants, hydraulic fluid, building components, coating agents, adhesives and many other uses.
