摘要： 57 A process for producing silicon hydrides represented by the general formula Si n H 2n+2 wherein n is a positive integer of 1 to 6 comprises reacting a silicon-containing alloy with an aqueous solution of an acid in the presence of at least one inert organic solvent having a boiling rante of from -60°C to 250°C. The presence of the organic solvent leads to improved yields and reduced interference from solids formed in the reaction vessel.
