FIELD: production of sodium borohydride.
SUBSTANCE: group of inventions can be used as a carrier and source of hydrogen. The method for producing sodium borohydride includes the reaction of sodium borate and aluminum powder in an atmosphere of hydrogen gas with stirring at a temperature not lower than 400°C and not higher than 560°C. The molar ratio of sodium contained in sodium borate to boron contained in sodium borate is more than 1.0. Embodiments of the method for obtaining sodium borohydride are proposed.
EFFECT: group of inventions makes it possible to simplify the production of sodium borohydride using aluminum as a reducing agent.
