| titleOfInvention | METHOD FOR CLEANING ROLL WATER SYNTHESIS OF SODIUM ASIDE |
| abstract | 1. The method of purification of mother waters of the synthesis of sodium azide containing hydrazine, ethyl alcohol and sodium azide, including their oxidation, characterized in that the oxidation of hydrazine is carried out with hydrogen peroxide in the mother water, and ethyl alcohol and sodium azide in the form of a volatile compound blow air from the mother water followed by oxidation of the vapor-air mixture on the catalyst. 2. The method according to claim 1, characterized in that the oxidation of hydrazine with hydrogen peroxide is carried out at a pH of 10 and a temperature of 60 ° C for 2 hours. The method according to claim 1, characterized in that the conversion of sodium azide into a volatile compound, hydrogen nitride, is carried out by acidifying the mother liquor with sulfuric acid to a pH of 1.65.4. The method according to claim 1, characterized in that the blow-off of ethyl alcohol and hydrogen nitrogen from the mother water by air is carried out at a temperature of 60 ° C. The method according to claim 1, characterized in that the oxidation of vapors of ethyl alcohol and hydrogen nitride is carried out with atmospheric oxygen on an aluminum-chromium catalyst at a temperature of 300-350 ° C and W = 10000 hours |
