Description and Uses
Dimethyl mercury is a volatile colorless liquid with faint sweet odor. Molecular weight= 230.67;Boiling point=96℃. Soluble in water. Methyl mercury chloride is a colorless, crystalline solid. Molecular weight= 251.08; Freezing/Melting point=170℃. Practically insoluble in water; solubility= ,0.1 mg/mL at 21℃.
industrial and agricultural uses of the compound and its industrial production have generally been abandoned because of its high toxicity. Methylmercury remains of considerable concern, however, because of its continuous formation in the environment. In the aquatic environment, elemental mercury is first oxidized to the mercuric mercury ion (Hg2+ ), which may then become methylated to form methylmercury compounds, either by chemical or microbiologically catalyzed reactions. Methylmercury is accumulated by fish and marine mammals and attains its highest concentrations in large predatory species at the top of the aquatic and marine food chains. By this means, methylmercury enters the human diet. Thus, minimization of environmental mercury contamination is imperative.
