【摘要】 碘代丙炔基正丁基氨基甲酸酯(IPBC)具有较好的杀菌效果,为了提高IPBC用于木材保护处理的抑菌性、防腐和防霉性能,合成4种IPBC衍生物。结果表明,其中3-碘代-2-丙炔-4-氯苯基氨基甲酸酯(衍生物1)和3-碘代-2-丙炔基-3,4-二氯苯基氨基甲酸酯(衍生物2)的防腐性能优于IPBC,但差于对照试剂戊唑醇。衍生物1的防霉效果优于IPBC,但略差于对照试剂五氯酚钠;衍生物2的防霉效果优于IPBC和五氯酚钠。更多还原

【Abstract】 Iodopropargyl butyl carbamate(IPBC)has demonstrated a great potential in wood preservation.In order to improve the bacteriostasis of IPBC,IPBC was modified by substituting its R group with 4–chlorophenyl,3,4-dichlorophenyl,4-p-tolyl and 4-methoxybenzene substituent and as a result obtained four kinds of IPBC derivative.The results showed that the bacteriostasis of 3-Iodo-2-propynyl 3,4-dichlorobenzene carbamate was better than that of IPBC and that of 3-Iodo-2-propynylp-chlorophenyl carbamate was comparable to IPBC.The mold resistance of 3-Iodo-2-propynyl 3,4-dichlorobenzene carbamate was better than IPBC and pentachlorophenol sodium, while the mold resistance of 3-Iodo-2-propynylp-chlorophenyl carbamate was slightly worse than pentachlorophenol but better than IPBC.The results of laboratory decay resistance of two derivatives were better than IPBC,but worse than that of tebuconazole.更多还原
