Abstract
THE investigation into the composition of the sulphur bodies present in the kerosene boiling-range of a Middle East crude oil distillate (Agha Jari, South Iran) has indicated that the sulphuric acid-soluble neutral compounds consist mainly of fully hydrogenated mono- and bi-cyclic sulphides with smaller amounts of alkylated thiophenes. A solid sulphur-containing compound is also present which collects as a sublimate in the column head during the fractionation when the column head reaches 78° C. at 3 mm. mercury pressure. This solid can be purified by sublimation or recrystallization, and forms sweet-smelling crystals which melt in a sealed tube at 320° C. with decomposition. Analysis gives the empirical formula C9H14S.
