차아브롬산 나트륨 C화학적 특성, 용도, 생산
Synthesis
A 40% sodium hydroxide solution (438 g., 306 ml.) is stirred and cooled to —3°C in a wide-neck, round-bottom flask closed with a three-hole rubber stopper (for a stirrer, dropping funnel and thermometer). Bromine (314 g., 100 ml., 90% of the quantitj theoretically needed for 175 g. of NaOH) is slowly added (1-2 drops per second) with constant stirring. The temperature of the reaction mixture is held between —8 and —3°C. Insufficient cooling results in the formation of NaBrO3; cooling below —8°C should be avoided to prevent slow solidification of the flask contents.Br2 + 2 NaOH + 4 H2O = NaBrO ? 5 H2O + NaBr
