Abstract
An effective inhibitor of the thermopolymerization of liquid pyrolytic products may be produced by a new method. The product, obtained by mild heat treatment of phenol byproducts from coke production in a mixture with turpentine and solvent, exhibits strong inhibiting properties in the heat treatment of pyrocondensates and significantly exceeds the effectiveness of the initial phenols and the well-known inhibitor ionol, which is a sterically hindered phenol.
