Ethylmercuric chloride water

Ethylmercuric chloride [107-27-7] M 265.1, m 193-194°. Mercuric chloride can be removed by suspending ethylmercuric chloride in hot distilled water, filtering with suction in a sintered-glass crucible and drying. Then crystd from ethanol and sublimed under reduced pressure. It can also be crystd from water. 

Dichloro(ethyl)arsine 485 Diethylmercury (150 g) is dropped into ice-cooled arsenic trichloride (150 g) a strongly exothermic reaction occurs and crystals separate. The mixture is finally heated for 0.5 h on a water-bath, then treated with anhydrous ether, filtered from the precipitated ethylmercuric chloride, and freed from ether. By repeated fractional distillation the dichloro(ethyl)arsine is separated from the excess of arsenic trichloride the yield of the former, b.p. 145-150°/760 mm, is 90 g.
