Procedure

A mixture of allyl bromide (100 g), sodium thiosulphate (212.5 g), ethanol (90 ml) and water (40 ml) was stirred and heated to reflux for 15 minutes, giving a homogeneous solution. The solution was allowed to cool somewhat, and ethanol and water were then evaporated under vacuum. The solid residue was added to absolute ethanol, and the solvent was then evaporated under vacuum to remove more water. The residue was stirred with hot ethanol (800 ml), and the suspension thus obtained was filtered. On cooling, the filtrate deposited a white solid (109.2 g). The NMR spectrum of the sold showed that it consisted of 80% by weight of sodium allylthiosulphate, 11% by weight of water and 9% by weight of inorganic salt.
