Abstract (en)
[origin: EP1279641A1] Production of sodium hydride (NaH) comprises: (1) adding a carbon-containing material under moisture- and oxygen-exclusion to a melt containing sodium hydroxide (and optionally also other alkali metal hydroxides) above the decomposition temperature (420 degrees C) of NaH; and (2) removing the reaction product from the reaction medium at ≤ 420 degrees C. An Independent claim for purification of sodium hydride (NaH) adding the impure NaH under moisture- and oxygen-exclusion to a melt containing sodium hydroxide (and optionally other alkali metal hydroxides) above the decomposition temperature (420 degrees C) of NaH and then removing the reaction product from the reaction medium at ≤ 420 degrees C.
