| abstract |
The invention relates to a method for producing hydrogen silanes of general formula R n Cl 3-n SiH by converting chlorosilanes of general formula R n Cl 4-n Si, where R, in both formulas simultaneously and independently of each other, is a hydrogen atom, an optionally substituted or unsubstituted hydrocarbon radical having 1 to 18 carbon atoms, and n can have the value of 1-3, and hydrogen gas in the presence of a catalytic quantity (K): zinc and/or an alloy comprising zinc on a metal oxide carrier. |
