METHOD FOR TREATING UTERINE WATER FUSION sodium azide

摘要

1. A method of purifying water uterine synthesis sodium azide containing hydrazine, ethyl alcohol and sodium azide comprising their oxidation, characterized in that the oxidation is carried hydrazine hydrogen peroxide in the mother waters, and ethyl alcohol and sodium azide as a volatile compound vented air from the mother water, followed by oxidation of vapor on katalizatore.2. A method according to claim 1, characterized in that the oxidation of hydrazine with hydrogen peroxide is carried out at pH 10 and a temperature of 60 ° C for 2 p.3. A method according to claim 1, characterized in that the transfer of sodium azide in volatile compound - nitrogen, hydrogen is conducted by acidification with sulfuric acid mother liquors to pH 1,65.4. A method according to claim 1, characterized in that the stripping of ethanol and hydrogen nitrogen air from the mother waters is carried out at a temperature of 60 ° C.5. A method according to claim 1, characterized in that the oxidation of ethanol vapor and nitrogen hydrogen with atmospheric oxygen is carried out at alyumomednohromovom catalyst at a temperature of 300-350 ° C and W = 10000 h.
