COMPOSITION INHIBITING POLYMERISATION WHEN PROCESSING LIQUID PYROLYSIS PRODUCTS, METHOD FOR PRODUCTION THEREOF AND METHOD OF INHIBITING POLYMERISATION WHEN PROCESSING LIQUID PYROLYSIS PRODUCTS Russian patent published in 2013 - IPC C07C7/20 C08F2/42 C07C39/08 C07C39/00 

FIELD: chemistry.

SUBSTANCE: composition further contains sulphate turpentine with molar ratio of phenol to turpentine of 1:(1-2), and the solvent used is a C2-C4 aliphatic alcohol or a mixture of a C2-C4 aliphatic alcohol and toluene in ratio of C2-C4 aliphatic alcohol to toluene of (90-50):(10-50) by volume, with ratio of turpentine to solvent of 1:(5-10) by volume, and said composition is treated at temperature of 130°C for 2 hours. The invention also relates to a method of producing said composition and a method of inhibiting polymerisation when processing liquid pyrolysis products by adding said composition to a pyrolysis condensate as an inhibitor.

EFFECT: high stability of the inhibiting composition and high stability of the process of inhibiting polymerisation of liquid pyrolysis products by using a composition containing simple unsubstituted phenols as an inhibitor.
