### Abstract

Experimental author results on the use of technogenic phenols as inhibitors are presented to undesirable polymerization in petrochemical manufactures. The basic ways of increase inhibiting properties of coke-chemical phenols are shown, such as rectification for separation of two-nuclear derivatives or some examples of their chemical modification, allowing to increase the inhibiting efficiency of phenolic mixes, for example, by novolak fenol-formaldehyde condensation or oxidative coupling reactions. The received derivatives of phenols are recommended both for processing pyrocondensates and for rectification of styrene.

Keywords: pyrocondensates, styrene, phenolic inhibitors, sterically hindered phenols, technological phenols, phenols from wood, coke-chemical phenols, increase inhibiting properties, rectification, chemical modification, phenol formaldehyde condensation, oxidizing coupling
