I-PBO Yokwenziwa Yama-Pyrethroids Ikhona Esitokweni

 Incazelo Yomkhiqizo

 I-Piperonyl butoxide esebenza kahle kakhulu (I-PBO) ingenye yezindlela ezivelele zokwandisa ukusebenza kahle kwezibulala-zinambuzane. Akugcini nje ngokuthi ingandisa umphumela wezibulala-zinambuzane izikhathi ezingaphezu kweshumi, kodwa futhi ingandisa isikhathi sayo sokusebenza.

 I-PBO iyi-synthesis material intermediate futhi isetshenziswa kabanzi kwezolimo, impilo yomndeni kanye nokuvikelwa kwesitoreji. Iyona kuphela egunyaziwe.Isibulala-zinambuzaneIsetshenziswa ekuhlanzeni ukudla (ukukhiqizwa kokudla) yi-UN Hygiene Organisation. Kuyisithasiselo sethangi esiyingqayizivele esibuyisela umsebenzi wokulwa nezinhlobo zezinambuzane ezingamelani. Sisebenza ngokuvimbela ama-enzyme akhona ngokwemvelo abengalimaza i-molecule yezinambuzane. I-PBO iphula ukuzivikela kwezinambuzane futhi umsebenzi wayo wokubambisana wenza i-insecticide ibe namandla futhi isebenze kahle.

 Indlela Yesenzo

 I-Piperonyl butoxide ingathuthukisa umsebenzi wokubulala izinambuzane we-pyrethroids kanye nemithi yokubulala izinambuzane ehlukahlukene njenge-pyrethroids, i-rotenone, kanye ne-carbamates. Iphinde ibe nemiphumela yokusebenzisana ku-fenitrothion, i-dichlorvos, i-chlordane, i-trichloromethane, i-atrazine, futhi ingathuthukisa ukuzinza kwezithako ze-pyrethroid. Uma usebenzisa i-housefly njengento yokulawula, umphumela wokusebenzisana walo mkhiqizo ku-fenpropathrin uphakeme kunowe-octachloropropyl ether; Kodwa maqondana nomphumela wokudonsa phansi ezimpukaneni zasekhaya, i-cypermethrin ayikwazi ukusetshenziswa. Uma isetshenziswa empephweni yokuxosha omiyane, awukho umphumela wokusebenzisana ku-permethrin, futhi ngisho nokusebenza kahle kuyancishiswa.
