Isibulali zinambuzane iTetramethrin Mosquito 95%Tc Ukulawula Iingcongconi Iimpukane Amaphela

I-Tetrametrin isetyenziswa kakhulu ngamandlaeyenziweyoIsibulali zinambuzanekusapho lwepyrethroid.Iqinile yikristale emhlophe. Imveliso yorhwebo ngumxube we stereoisomers.Idla ngokusetyenziswa njengeisibulali zinambuzane, kwaye ichaphazela inkqubo yemithambo-luvo yesi sinambuzane. Inokufumaneka kwiindawo ezininziIsibulali-zinambuzane saseKhayaiimveliso.Ifomula yobungqina nguC19H25NO4; ubunzima bemolekyuli yi-331.4. Ubume bayo yikristale engenambala; ubunzima bayo obuthile yi-1.1 ku-20 ° C; uxinzelelo lwalo lomphunga yi-0.944 mPa kwi-30 ° C; logKow= 4.6. Ayinyibiliki kancinane (1.83 mg/l) emanzini kwi-25°C, kodwa iyanyibilika kwiintlobo ezininzi ze-organic solvents. Ayizinzile kwi-asidi eyomeleleyo kunye ne-alkaline medium.

Isicelo

Isantya salo sokuya kwiingcongconi, iimpukane njl.njl. Ikwanalo nesenzo sokugxotha amaphela. Idla ngokuyilwa ngezibulali-zinambuzane ezinamandla amakhulu okubulala. Inokwenziwa ukuba ibe sisibulala-zinambuzane esitshizwayo kunye nesibulali sezinambuzane se-aerosol.

Ubutyhefu

I-Tetramethrin sisitshabalalisi esinetyhefu ephantsi. Acute percutaneous LD50 kwimivundla>2g/kg. Akukho ziphumo ezicaphukisayo kulusu, amehlo, impumlo, kunye nephecana lokuphefumla. Ngaphantsi kweemeko zovavanyo, akukho mutagenic, carcinogenic, okanye iziphumo zokuzala zabonwa. Le mveliso inetyhefu kwiintlanzi i-Chemicalbook, ene-carp TLm (iiyure ezingama-48) ze-0.18mg / kg. Igill eluhlaza okwesibhakabhaka LC50 (iiyure ezingama-96) yi-16 μ G/L. Izagwityi acute oral LD50>1g/kg. Ikwayityhefu kwiinyosi nakwimibungu yesilika.
