The preparation method of carbon selenide: a dry stream of N2 is saturated with CH2Cl2 vapor, and the gas mixture is introduced into a Vycor flask in which Se is heated to 550-600°C. The crude product precipitates in the receiver, equipped with a Liebig condenser. The cooling by the condenser is stopped and the liquid is forced with steam into a cooled flask, separated from the H2O and dried over CaCl2. It is then distilled at 46°C and 50 mm. in a fractionating column (30 cm. long). Preparation device of carbon diselenide
