CS2 - CARBON DISULFIDE

Properties of carbon disulfide:

It is colorless volatile liquid. Badly miscible in water, unlimitedly miscible with polar organic solvents. Well dissolves bromine, iodine, sulfur, white phosphorus. Reactive, flammable in air. It is hydrolyzed by water vapor, reacts with binary compounds of non-metals and metals. Reducing agent.


Molar mass g/mol 76.14
Density g/cm3 1.261
Boiling point °C 46.24

Methods for preparation of carbon disulfide:

C + 2S = CS2 (700-800° C).


Chemical reactions with carbon disulfide:

CS2 + 2H2O(vapor) = CO2 + 2H2S (150° C, impurity CSO).

CS2 + Ba(OH)2 = BaCO3↓ + BaS + H2O.

CS2 + 2(NH3 • H2O) + Ca(OH)2 = NH4NCS + CaS↓ + 4H2O (110° C, p).

CS2 + 4H2 = 2H2S + CH4 (above 50° C, catalyst Pt/MoS2).

CS2 + 3O2 = CO2 + 2SO2 (burning on air).

CS2 + 3Cl2 = CCl4 + S2CL2 (catalyst MnCl2/AlCl3).

CS2 + 3Cl2O = CCl2O + 2SCl2O, CS2 + 3SO3 = CSO + 4SO2 (normal temp.),

CS2 + 2SnO = CO2 + SnS (220-300° C).

CS2 + PCl5 = CSCl2 + PSCl3.

CS2 + K2S(conc.) = K2CS3.

CS2 + CaCN2 = C2N2 + CaS + S (700-850° C).

3CS2 + 4KMnO4 + 2KOH(diluted) = 6S↓ + 4MnO2↓ + 3K2CO3 + H2O.
