摘要：
Fast 8-MeV electrons were used for the heating and dry distillation of hydrolytic lignin. The resulting tar differed in composition from that of the conventional dry distillation and was composed primarily of methoxyphenols. Guaiacol and creosol were the prevalent components in the fraction with the boiling range 80–235°C. It was shown that the tar effectively inhibits the thermal polymerization of styrene, with the inhibiting activity being higher than that of the commercial inhibitors Agidol 1 and Agidol 2. In the presence of 0.025 wt % tar, the induction period of the thermal polymerization of styrene at 120°C was at least 120 min.
