A solution of hypochlorite is stable in an excess of alkali, whereas in acid there is a slow conversion to chlorate. The minimum stability of hypochlorite solutions is at pH 6.7 (6.68 and 7-7.13 have also been reported - ) and the maximum stability is at pH 13. There is also a region of high stability in strong acid, where the solute is predominantly composed of chlorine and only very little hypochlorous acid. The rate of decomposition at pH 6.7-7.2 is proportional to the chloride concentration and to the square of the hypochlorite concentration. In slightly alkaline solution the rate is proportional to [0C1-][H0C1]. The catalytic effect of chloride ion is well known buffers " such as acetate, borate and carbonate also have an effect. It has been recommended that the concentration of phosphate buffers be kept below 0.25 M to prevent decomposition of hypochlorite solutions. The catalytic effect of heavy metals, especially copper and iron, has been noted. The effect of various cations is shown in the greater stability of lithium hypochlorite in comparison with the sodium and potassium salts. ... [Pg.137]

The reaction is carried out in a Schlenk tube, Fig. 1. Acetone (10 mL) is cooled in an ice bath and saturated with carbon monoxide by passing in a brisk stream of the gas for 10 minutes. Potassium hydrotris(pyrazolato)borate (252 mg, 1.0 mmole) and copper(I) chloride (99 mg, 1 mmole) are added to the acetone, and the mixture is stirred for 30 minutes while continuing to pass a slow stream of carbon monoxide. At the end of this period, the white suspension is filtered, using the Schlenk-type apparatus illustrated, Fig. 2, keeping the whole under an atmosphere of CO. The clear colorless filtrate is evaporated to dryness, and the cream-colored residue is extracted with 10 mL light petroleum (boiling range 40-60°, saturated with CO) and filtered. Evaporation of the solvent from the filtrate affords a white powder of Cu(CO)[(pz)3BH] (156 mg, 51%). [Pg.108]
