PROBLEM TO BE SOLVED: To obtain a nitrogen-containing saline compound as a starting raw material for producing a silicone nitride ceramic excellent in high temperature strength by carrying out a reaction of silane halide with liquid ammonium. SOLUTION: In a reaction system wherein liquid ammonium containing 35-160ppm of water and an organic solvent which is inactive to liquid ammonium and silane halide, is not soluble in liquid ammonium at the reaction temperature and has specific density greater than that of liquid ammonium, exist separately in two layers by the difference of specific gravity, the mixture of silane halide and organic solvent is supplied to the lower part of the reaction system to carry out the reaction of liquid ammonium with silane halide to obtain a reaction product. The reaction product is washed with liquid ammonium containing 35-160ppm of water and 600-2000ppm of organic solvent to give a nitrogen- containing silane compound constituting of silicone diimide containing 0.9-3.5wt.% of oxygen and 0.5-2.5wt.% of carbon. |
