Thionyl chloride has a long shelf life, however "aged" samples develop a yellow hue, possibly due to the formation of disulfur dichloride. It slowly decomposes to S 2 Cl 2, SO 2 and Cl 2 at just above the boiling point. [9] [12] Thionyl chloride is susceptible to photolysis, which primarily proceeds via a radical mechanism. [13]

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
