By the action of aqueous alkalis, carbon bisulphide is converted into a mixture of an alkaline carbonate and an alkaline thiocarbonate (J.
It Is Also Formed When Sulphur Trioxide Reacts With Carbon Bisulphide At 100° C., Cs2 3S03 =Cos 4So 2, And By The Decomposition Of Ethyl Potassium Thiocarbonate With Hydrochloric Acid, Co(0C2115)Sk Hc1= Cos Kc1 C 2 H 5 Oh.
On entering the first purifier, which contains calcium thiocarbonate and other combinations of calcium and sulphur in small quantity, the sulphuretted hydrogen and disulphide vapour have practically no action upon the material, but the carbon dioxide immediately attacks the calcium thiocarbonate, forming calcium carbonate with the production of carbon disulphide vapour, which is carried over with the gas into the second box.
In the second box the formation of calcium thiocarbonate takes place by the action of carbon disulphide upon the calcium sulphide with the liberation of sulphuretted hydrogen, which is carried over to the third purifier.
