| 要約: | The treatability ofthree tropical wood species namely Alstonia scholar is (pulai), Macaranga triloba
(mahang) and Hevea brasiliensis (rubberwood) was investigated Wood species were chemically treated with
five newly synthesized organotin(lV) complexes using full-cell treatment method This study explored whether
tropical wood species could be treated successfully with newly synthesized organotin(IV) complexes as wood
preservatives. Ten 19x19x19 mm sized wood cubes of each species were treated with three levels of
concentration (0.1, 0.5 and 1 %) ofmono me thyltin (IV) (MMI') andmonophenyltin(IV) (MPT) ofmono series and
dimethyltin(IV) (DMT), diphenyltin(IV) (DPT) and dibulyltin(IV) (DBT) ofdiseries organotin(IV) complexes with
2-acetylpyridine-N (4)-cyclohexyl thiosemicarbazone ligand The treated wood species were evaluated by
chemical retention values and characterized by FT -IR (Fourier Transform Infrared) spectroscopy analysis. The
highest retention (10.59 kg m-1) was found in Alstonia scholaris treated with 1% DMT complexes and the
lowest retention (0.47 kg m -') was found inHevea brasiliensis treated with OJ % DMT complexes. FT -IR spectra
oftreated wood showed new absorption bands in the range of 594-606 and 441-457 em-I due to Sn-C and Sn-N
bonds, respectively. A newly formed absorption band at range 549-569 cm-1 due to Sn-O band was also
observed in the treated wood sample spectra. Chemical retention and FTIR spectra suggest tropical wood
species are treatable with newly synthesized organotin(IV) complexes as wood preservatives. |
