When aniline is treated with mercuric acetate in aqueous solution at room temperature a mixture of o- and p-aminophenylmercuric acetates is formed,... 

The isomeric o-aminophenylmercuric acetate is difficult to separate from the larger amount of the p- compound which would separate with it if the filtrate from the initial crop of the p- acetate were allowed to stand. Dimroth found, however, that there was a considerable difference in the solubilities of the chlorides, so the filtrate is treated with an excess of sodium chloride solution, precipitating p-aminophenylmercuric chloride in the amorphous state, while the 0-amino chloride separates in crystalline form. The mixture is sucked off, dried, and the 0- derivative extracted with not too much warm alcohol, separating as leaflets after the solution is chilled and allowed to stand The amorphous residue of p- chloride may be boiled with alcohol or benzene, and separates from the cold solution as leaflets melting at 1880, with decomposition. 

The following p-aminophenylmercuric salts are obtained by the action of the corresponding alkali salts on. the acetate bromide, colourless lamina , M.pt, 182° C. iodide, M.pt. 165° C. (with decom-])Ositi(>n) nitrate, microscopic crystals sul Aiate, needles, M.pt. 150° C. (witli decomposition) thiosulphate, colourless plates, M.pt. 95° C. (with decomposition).
