Research of
structural and group structure of organosulfur compounds of the Bavly oil by an
adsorptive method
Abstract
The
structural and group structure and properties of organosulfur connections of
oil fraction of the Bavlin petroleum. With
application of a method of polarographic spectroscopy definition of element
sulfur, hydrogen sulfide and mercaptans in the narrow aromatic fractions
adsorbed by ASL grade silica gel was carried out and established that the
above-stated organosulfur connections in oil fraction of the Bavlin oil are
absent. It is shown that the bulk of organosulfur connections is
presented by sulfides in number of 64.7%. With use of methods of mass
spectroscopy it was established that sulfides of oil fraction in the structure
contain generally saturated connections in lack of aromatic sulfides.
Organosulfur connections of an empirical formula CnH2n–4S of oil fraction contain
35.3% of derivatives of the thiophenes which are generally presented from 64 to
80% by alkylthiophenes. On the second place according to contents, from 15 to
21%, there are connections of a formula CnH2n–6S which represents tiaindana.
Key words:
Bavlin oil, organo-sulfur compounds, adsorption separation.
