摘要


有機錫木材防腐劑R3SnX之抗菌抗蟲能力端視R3Sn之種類及生質而定。通常3個R基之總碳原子數以9-12個爲最佳。X基雖對防腐性能並無明顯的影響,但對溶劑之溶解性質則有顯著的作月,有機錫化合物之水溶性極低,當X爲烷化磺酸基(R'SO(上標 3-))時其水溶性可提高到到0.1~1.5%w/v,其中R3SnSO3R'的R=n-C4H9, R'=C2H5時,其溶解度可高達1.1~1.5%,足供木材防腐之處理。本報告記述此類化合物之合成以及在水中之溶解度。

並列摘要


The biological activity of organotin wood preservatives is essintially dependent on the type and structure of R3Sn group, bat unaffcctcd by the nature of anionic group X. A total number of 9-12 carbon atoms in R3Sn group performs the highest fungal toxicity. However, X group affects its solubility. When X=R'S03 in R3SnSO3 R', the aqueous solubility becomes 0.1-1.5% w/v. When R=n-C4H9, R'=C2H5 it reaches remarkbly high (1.1-1.5%). The synthesis and the water solubility of water borne triorganotins are described.
