Sulphides and thiophenes of sulphur petroleum distillates
Abstract 1. The structural group composition of sulphides and thiophenes of middle distillates of mercaptan (Orenburg), sulphide (Samotlor) and thiophene (Usinsk) type sulphurous petroleums are compared. 2. Sulphides in Usink distillate are wholly represented by thiaindanes. Thiamono- and thiabicycloparaffins (their total being 54·8 and 72·2% of sulphides, respectively) dominate the sulphides of Orenburg and Samotlor distillates. Thiaparaffins figure significantly in the Orenburg distillate where they form 13·7% of the sulphides. 3. Maximum aromaticity of thiophene compounds of Orenburg petroleum distillate and maximum cyclic recurrence in Usink petroleum distillate was established. 63·5% of the thiophenes of the Samotlor distillate is represented by polyalkylthiophenes and alkylbenzothiophenes.
