Studied the thermal destruction of pine wood in a nitrogen atmosphere. As modifiers used in aqueous solutions boron- nitrogen compounds. Found that the modification of pine boron- nitrogen compounds leads to partial cross-linking (enlargement) of the fragments of carbohydrates and lignin, which will reduce the output of low-molecular compounds forming fraction of combustible volatile thermal decomposition products in a nitrogen atmosphere. Moreover, as a consequence, decreases the value of the mass loss of modified pine wood samples compared to non-modified samples. Changes in the chemical composition of the surface of the wood as a result of the modifications amine borates facilitates the process of carbonization.
