| SODIUM HYPOBROMITE Usage And Synthesis |
Uses | Sodium hypobromite is an inorganic salt compound, which can be used as an intermediate in the synthesis of medicine and chemical industry. | Preparation | Sodium hypobromite can be prepared by the following methods:dissolve part of sodium hydroxide in water, cool it to below 10°C, add bromine to react, and keep the temperature below 10°C. | Chemical Properties | Formula weight (NaBrO) 118.91. Yellow crystals, readily
soluble in H2O. May be stored at —20°C in a closed weighing
vessel for a few days with only slight loss of NaBrO; decomposition, with formation of NaBr and NaBrO3, begins immediately at 0°C and is complete within two days. Analysis after drying for one or two hours on clay at 0°C; about
92% NaBrO·5H2O, 2% NaBr·2H2O, 1% NaBrO3, 5% moisture. | 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
