Аннотация: Lignin, being the basic component of wood, since ancient days was the main source of wood tar. Due to diversity of valuable properties, tar had application as lubricant, protective impregnant for wooden and leather products, insect repellant, odorant, cosmetic and edible ingredient, spice for meat, natural dye for production of paints, chemical reagent, etc. Till now tar is widely used as bio-protection agent. In the last century tar has been recognized as inexpensive and available polymerization retarder, in particular, as inhibitor of styrene thermopolymerization. Such ability of tar results from presence of various phenols. However inhibiting effect of wood tar is rather small as phenols in tar are diluted with other components which are not possessing inhibiting properties. Both composition and inhibiting properties of tar improve essentially when tar is forming in the course of an irradiation of lignin or lignocelluloses. Triple increase in productivity of lignin-to-tar conversion takes place via radiation-stimulated distillation of the lignin moreover the obtained tar represents a concentrate of phenols and benzenediols. The inhibiting ability of tar can be increased additionally due to presence of heavy alkanes at feedstock being irradiated. The report informs of a technique of electron-beam distillation of lignin and of composition distinctivenesses of tar. * corresponding
