addition to forming monosilanes, produces a high-boiling
component which can constitute as much as ten percent of the
resultant product (Chadwick, column 1, lines 64-69). The high
boiling component is a complex mixture that include, silicon
containing compounds, silicon particulate and soluble and
insoluble compounds of copper, aluminum and zinc (Chadwick,
column 1, lines 48-60). The Chadwick invention is directed to
a process of converting the high boiling component to
monosilanes by contacting the high boiling component with a
hydrogen gas at a temperature of 250-1000 C.o
Burgie is directed to a process for separating
particulate silicon from a liquid or liquid by-product stream
containing silanes by atomizing into a heated zone the silane
containing liquid to dry the silicon particulate.
Ritzer is directed to a process of rendering the high
boiling component, a component that is highly reactive and
exothermic upon exposure to moisture, stable to permit
transportation and disposal of the component. Ritzer
deactivates the high boiling component by pelletizing the high
boiling component and impregnating the pellets with a binder
that may applied in solution or emulsion. The solvent or
