Abstract
Physicochemical characteristics of thermolysis oil obtained from polypropylene have been determined. The hydrocarbon composition, studied by two-dimensional gas chromatography and high performance liquid chromatography, as well as calculation of the iodine value, shows that the major components of the resulting oil are isoalkanes and alkenes. The results obtained allow us to draw conclusions about the mechanism of polypropylene transformation during thermolysis, and data on the fractional composition, density and viscosity further characterise thermolysis oil from the perspective of a petroleum product.
