Abstract
A process for the production of silane in a reaction vessel comprising (i) a single closed chamber, (ii) a hollow tube open at both ends, said tube being disposed in the lower portion of the chamber; and (iii) means for circulating liquid in the lower portion of the chamber in such a manner that the liquid flows in a downward direction through the tube and in an upward direction outside of the tube Comprising the following steps: PA1 A. maintaining a melt of lithium chloride in the lower portion of the chamber, the level of the melt being above the tube; PA1 B. activating the circulating means; PA1 C. introducing liquid lithium into the melt in such a manner that at least a part thereof is brought to the surface of the melt; PA1 D. introducing hydrogen gas above the surface of the melt in such a manner that hydrogen gas reacts with lithium at the surface of the melt to form lithium hydride, PA2 The lithium, lithium hydride, and melt being admixed by the circulating means to provide a homogeneous mixture thereof; PA1 E. introducing, as a gas, a compound or a mixture of compounds having the formula EQU SiH.sub.x Cl.sub.4.sub.-x PA1 wherein PA2 x is 0 or an integer from 1 to 3 PA1 in …
