Kohlenstoffdiselenid is an inorganic chemical compound of carbon from the group consisting of selenides.

Production and representation

Kohlenstoffdiselenid can be obtained by the reaction of selenium with dichloromethane at 520 ° C.

Also possible is the preparation by reaction of hydrogen selenide with tetrachloromethane.

Properties

Kohlenstoffdiselenid is a golden yellow, strongly refractive liquid, which smells like rotten radish and is insoluble in water. It is provided with yellow color soluble in carbon disulfide, carbon tetrachloride, ether, benzene, nitrobenzene, dioxane, ethyl acetate, acetone, but slightly soluble in glacial acetic acid and alcohol. The compound is very sensitive to light. You polymerized on standing until brown then black, but kept almost indefinitely at -30 ° C in the dark. She goes on heating in a sealed tube at 150 ° C in a black solid mass on. Sulfur powder hardly dissolves in Kohlenstoffdiselenid abundant, red selenium. When heated, the compound decomposes on contact with nitric acid and sodium hydroxide. Through a high-frequency discharge may consist of its carbon mono -selenide obtained ( structure similar to carbon monoxide ).
