Kupu Whakataki
Ko te 3-Chloro-4-methylpyridine he pūhui waro. Ko ona ahuatanga e whai ake nei:
1. Te ahua:3-chloro-4-methylpyridinehe wai kore tae ki te kowhai marama.
2. Kiato: 1.119 g/cm³
4. Wairewa: Ko te 3-chloro-4-methylpyridine he wairewa i roto i te nuinga o nga whakarewa waro me te kore e rewa i te wai.
Ko nga whakamahinga matua o te 3-chloro-4-methylpyridine e whai ake nei:
1. Te whakahiatotanga o nga huinga konganuku whakawhiti: He takawaenga nui e whakamahia ana i roto i te matū ruruku mo te whakahiatotanga o te waipiro amino, te waikawa amino, me etahi atu pūhui heterocyclic hauota.
2. Nga takawaenga pesticide: Ka taea te whakamahi 3-chloro-4-methylpyridine hei takawaenga i roto i etahi ngarara me nga otaota.
Ko te tikanga mo te whakarite 3-chloro-4-methylpyridine te nuinga o nga waahanga e whai ake nei:
1. Tauhohenga hauota o te pyridine: ka tauhohehia te pyridine ki te waikawa nitric me te waikawa pungatara kia whiwhi 3-nitropyridine.
2. Te tauhohenga whakaheke: Ka tauhohehia te 3-nitropyridine me te taikaha o te sulfoxide me te kaihoko whakaheke (penei i te paura zinc) kia whiwhi ai i te 3-aminopyridine.
3. Te tauhohenga o te chlorination: Ka tauhohehia te 3-aminopyridine me te thionyl chloride kia whiwhi 3-chloro-4-methylpyridine.
Ko nga korero haumaru e tika ana mo te 3-chloro-4-methylpyridine e whai ake nei:
1. Te whakamohiotanga: He tauhohenga mate pawera ki etahi taupori.
2. Te irirangi: Ka pa te kino ki nga kanohi, te punaha manawa me te kiri.
3. Paitini: He paitini ki te hauora o te tangata, me whai i nga tikanga whakahaere haumaru.
4. Rokiroki: Me penapena ki roto i te ipu hau, kia matara atu i te mura me te waiora, kia matara atu ki te hau.
I te wa e whakamahi ana i te 3-chloro-4-methylpyridine, whai i nga tikanga haumaru e tika ana penei i te mau i nga kaakahu tiaki, nga karapu me nga kakahu whakamarumaru, me te whakarite kei te whakahaeretia i roto i te waahi pai te hau. Ki te pa mai, ka werohia ranei, me rapu wawe i te rongoa ka whakaatu i te Pepa Raraunga Haumaru o te hua ki to taakuta.
