Abstract: Disilane Si.sub.2 H.sub.6 is obtained with good yield by reduction reaction of Si.sub.2 Cl.sub.6 with a mixture of LiH and LiAlH.sub.4 in an organic liquid medium such as n-butyl ether. Usually the reaction temperature is -25.degree. C. to 50.degree. C. A suitable range of the mole ratio of LiH to LiAlH.sub.4 is from 0.8 to 40. It is impracticable to reduce Si.sub.2 Cl.sub.6 to Si.sub.2 H.sub.6 by using LiH alone as the reducing agent, but the reaction proceeds smoothly when a LiH/LiAlH.sub.4 mixture is used. The use of the mixture is economically advantageous over the use of expensive LiAlH.sub.4 alone.
