The invention discloses a metal sodium safety treatment method capable of avoiding hydrogen generation, and solves the problems that in the prior art, generation of explosion and a great volume of hydrogen cannot be avoided in a metal sodium treatment process, the operation is fussy, potential safety hazards are still serious, and meanwhile, environmental pollution is also easy to cause. The metal sodium safety treatment method comprises: (1) under the protection of nitrogen, placing metal sodium into a reaction kettle with an alkane-containing solvent, heating to melt the metal sodium, and stirring to form fine sodium balls; (2) slowly dropwise adding a mixture of amide and halogenated hydrocarbon RX, performing a heat preservation reaction to convert the metal sodium into an alkyl sodium intermediate state RNa and sodium halide, enabling part of the intermediate state RNa to react with the halogenated hydrocarbon RX to form bi-alkyl hydrocarbon R-R and sodium halide, and enabling the intermediate state RNa which is incompletely converted to react with quantitatively added water to form alkyl hydrocarbon RH and sodium halide. The metal sodium safety treatment method has the advantages of no severe heat release, no generation of inflammable and explosive hydrogen gas, mild condition and very high safety controllability.
