Abstract

The experimental results indicated that the compound 3,5-di-(1-adamantyl)-2-hydroxyphenol was a highly ef-fective inhibitor in processing liquid pyrolysis products (pyrocondensate). In laboratory conditions the phenolic com-pound very eff ectively inhibited the formation of polymer deposits formed from unsaturated compounds in pyrocon-densate K-27. On pyrocondensate K-27, the inhibitory eff ectiveness of 3,5-di-(1-adamantyl)-2-hydroxyphenol varied from 45 - 90% in the concentration range of 0.01 - 0.05% of mass. The fi gures are about 1.2 - 1.3 times higher than that of the inhibitor 4-tert-butyl-2-hydroxy-phenol which is used for stabilising liquid pyrolysis products of Angarsk Petrochemical Complex in the Russian Federation. The experimental data showed that the new inhibitor should be used in the concentration range of 0.02 - 0.04ppmw to get the highest economic and inhibitory eff ectiveness
