Any other information on results incl. tables
Spontaneous ignition upon mixing was not observed.
In each case, the average burning time of the individual sulphuryl dichloride / cellulose mixture is considerable longer than the reference values.
Further, sulphuryl dichloride reacts with the hydroxy groups of cellulose in the following principal manner:
R-OH + SO2Cl2 → R-O-SO2Cl + HCl
R’-OH + R-O-SO2Cl → R’-O-SO2-O-R + HCl
Therefore, sulphuryl dichloride exhibits the behaviour of a typical inorganic acid chloride. The reaction taking
place is not an oxidation; the pressure rise may be primarily attributed to the formation of HCl and not CO2 and
H2O which should be formed in an oxidation reaction.
Therefore, sulphuryl dichloride is not to be classified as an oxidising liquid.

- Executive summary:
Klein A and Heitkamp D (Currenta, 2010)
The average burning time of the individual sulphuryl dichloride / cellulose mixture is considerable longer than the reference values (50 % perchloric acid / cellulose (1:1); 40 % aq. sodium chlorate / cellulose (1:1); 65 % aq. nitric acid / cellulose (1:1).
Sulphuryl dichloride exhibits the behaviour of a typical inorganic acid chloride. The reaction taking
place is not an oxidation; the pressure rise may be primarily attributed to the formation of HCl and not CO2and
H2O which should be formed in an oxidation reaction.
Therefore, sulphuryl dichloride is not to be classified as an oxidising liquid.
