The study of byproduct of ethylene production with light pyrolysis resin and properties of obtained varnish

The composition of the light pyrolysis resin has been studied with the methods of gas-chromatographic and mass-spectrometry analysis. 70.24 % of aromatic, 8.53 % of saturated and 7.83 % of non-saturated hydrocarbons have been revealed in the sample. Aromatic hydrocarbons with high content percentage of the light pyrolysis resins have been rectified. The treatment of the oil-polymer resin into the varnish in the distillation residue has been researched. It was defined that the varnishes are stable against the reactions of the acids, salts, alkali, sea water and mineral oil, and do not have electrical conductivity. Moreover, it was also revealed that a varnish obtained with an aluminum complex catalyst on toluol is of higher quality than that of obtained via thermal treatment.
