Formation of alkylmercury compounds by ultraviolet irradiation of inorganic mercurial together with organic compounds in water was examined. The aqueous solution (100ml) of mercuric chloride (2 mmoles) was irradiated in the presence of acetic acid, propionic acid, methanol, or ethanol (10 mmoles) for 20 hr with ultraviolet ray (2537 Å) at 20°, and the reaction products isolated by the extraction method for alkylmercury compounds were subjected to qualitative and quanti tative analyses using thinlayer chromatography, mercury analyser, and gas chromatography. It was found that irradiation of mercuric chloride in the presence of acetic acid, methanol, or ethanol in water gave methylmercury compound in 0.12, 0.00006, and 0.02% yield of respectively. Irradiation of mercuric chloride in the presence of propionic acid gave methylmercury and ethylmercury compounds at the proportion of 0.00046 and 0.00004%, respectively.
