Abstract

See full text

In order to separate diborane from a gas mixture containing diborane and hydrogen, the gas mixture is normally cooled in a storage tank using liquid nitrogen, wherein the diborane freezes out. In order to enable an extensively continuous separation of the diborane from the gas mixture, according to the invention, the gas mixture is brought into thermal contact with a liquefied gas in a heat exchanger, which liquefied gas is held at a pressure such that the diborane is liquefied by the thermal contact with the coolant, and the liquefied diborane is then discharged from the first heat exchanger and supplied to a storage tank. In a downstream, second heat exchanger, the diborane remaining in the gas mixture can then be caused to freeze out.
