Abstract
The behavior of carboniferous impurities during thermochemical purification of sulfur was studied. The integral absorption coefficient for the IR absorption band at 2920 cm-1, related to aliphatic hydrocarbons, was determined. The detection limit for aliphatic hydrocarbons in sulfur was evaluated to be 2 x 10-5 wt % (3σ criterion).
