 Method/Apparatus/Procedure:
   A 20 cm3 1,2-dibromoethane sample was mixed with 40 cm3 aqueous electrolyte solution in a flask fitted with a thermostat jacket and a powerful stirrer. After a stirring time of 2-3 days, samples were taken from  both phases for analysis. The bromine concentration was determined by adding HNO3 to the solution and the free bromine was titrated with AgNO3 solution. The water content of the organic rich phase was calculated by the  method of Kariusu.1
