    Description

    N,N-dimethyl amino carbinol catechol borate(1). N,N-dimethyl amino carbinol-4-methyl catechol borate(2), N,N-dimethyl amino carbinol-4-t- butyl catechol borate(3). N,N-dimethyl amino carbinol-2,3-naphthyl borate 4) were synthesized by refluxing boric acid and diol in DMF(N,N-dimethyl formamide). The borates were characterized by NMR. Wood impregnated with borate 1,2 or 4 after 2-week water leaching was able to prevent decay by a brown-and white-rot fungus. TGA showed that wood impregnated with borate 1 or 4 had a high char yield. DSC showed that the pyrolysis pathway of wood treated with borates proceeds by depolymerization.
