Chemistry of imidobis(sulphuryl chloride)—IV measurements of physical properties of imidobis(sulphuryl chloride)

Density, viscosity and specific conductance have been measured at 5° interval between 25 to 50° for imidobis(sulphuryl chloride). The surface tension, freezing point and cryoscopic constant have also been determined. Its IR and proton NMR spectra have been recorded. Relative acidity strength measurements in acetic acid suggest that imidobis(sulphuryl chloride) is a stronger protonic acid than HBr, HSO3Cl and (CF3)2POOH.
