2,3,6-TRICHLOROPHENOL is incompatible with acid chlorides, acid anhydrides and oxidizing agents. .
LAC-4 (a laccase purified from Ganoderma lucidum) had a strong ability for 2,6- dichlorophenol (2,6-DCP) and 2,3,6-trichlorophenol (2,3,6-TCP) degradation. LAC-4 also had a good degradation effect on the chlorophenol mixture (2,6-DCP + 2,3,6-TCP). The results of the kinetics of the degradation of chlorophenols by LAC-4 suggested that the affinity of LAC-4 for 2,6-DCP was higher than that of 2,3,6-TCP. The catalytic efficiency and the catalytic rate of LAC-4 on 2,6-DCP were also significantly higher than 2,3,6-TCP. During the degradation of 2,6-DCP and 2,3,6-TCP, LAC-4 had a strong tolerance for high concentrations of different metal salts (such as MnSO4, ZnSO4, Na2SO4, MgSO4, CuSO4, K2SO4 ) and organic solvents (such as ethylene glycol and glycerol). The free radicals formed by LAC-4 oxidation of 2,6-DCP and 2,3,6-TCP produced dimers through polymerization. LAC-4 catalyzed the polymerization of 2,6-DCP and 2,3,6-TCP, forming dimer products. LAC-4 catalyzed 2,3,6-TCP into two main products: 2,3,6-trichloro-4-(2,3,6- trichlorophenoxy) phenol and 2,2',3,3',5,5' -hexachloro-[1,1' -biphenyl]-4,4' -diol[1].
