A New Chemical Method of Wood and Bamboo Preservation Based on Bis(2-methylpiperazinedithiocarbamato) Cu(II) and Di(2-methyl-5-chlorophenyl) Dithiophosphinato Triorganotin(IV) Compounds

摘要

A new method of wood and bamboo preservation has been developed.Treatment of DMF solution of bis(2-methylpiperazine-dithiocarbamato) Cu(II),Cu(2-Mepipzdte)_2 and ethanolic solution of di(2-methyl-5-chlorophenyl) dithiophosphinato triorganotin(IV),R_3Sn(MeCldtpi),for 24 h followed by drying and treatment with kerosene oil prevented wood and bamboo from attack by fungus,bacteria and comon white ants.MIC values of these compounds against E.coli and wood degrading fungi Clostridium cumeni were evaluated.R_3Sn(MeCldtpi) was found to be a more effective antifungal and antibacterial compound.
