Electron spin resonance study of the cavitated larch wood

It was shown previously that the larch wood waste can be efficiently processed by passing as aqueous pulp through a disintegrator of cavitator type [1, 2]. By this procedure the wood waste is transformed into a new polymer material called “Cavitated wood.” Besides the cavitated wood, therewith are formed lowmolecular substances: the dihydroquercetin flavonoid, terpenes, terpenoids, etc. [2]. Apparently, the essence of the phenomenon lies in the reorganization of the polymer structure of the original wood raw material, by moving some of its –Ar–C–C–C–X nano-sized blocks. Let us call this lignin nano-isomerization.
