Kupu Whakataki
Ko te 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine he pūhui waro. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, nga tikanga whakangao me nga korero haumaru:
1. Taiao:
- Te ahua: 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine he toka kore tae ki te kowhai kowhai.
- Wairewa: He tata kore e rewa i roto i te wai, engari ka whakarewahia i roto i nga whakarewa waro penei i te ether, methanol me te methylene chloride.
- Ko nga ahuatanga matū: He pūhui kawakore e mahi ana i te tauhohenga whakaheke ki te waikawa. Ka taea hoki te whakamahi hei reagent fluorinating hei whakauru i nga roopu trifluoromethyl ki etahi atu puhui waro.
2. Whakamahinga:
- Ko te 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine e whakamahia nuitia ana i roto i nga tauhohenga whakahiato waro hei whakakorikori, reagent ranei. Hei tauira, ka taea te whakamahi hei hanga i nga here waro-fluorine me nga tauhohenga amination.
- Ka taea hoki te whakamahi hei rauemi timatanga, takawaenga ranei mo te whakahiato pesticide.
3. Tikanga:
- Ko te tikanga whakarite ko te tauhohe i te pyridine me te waikawa trifluoroformic me te waikawa pungatara ki te whakaputa 3-chloro-2-hydroxy-5-(trifluoromethyl)pyridine.
4. Mōhiohio Haumaru:
- Me karohia te 3-Chloro-2-hydroxy-5-(trifluoromethyl)pyridine i te wa e rokiroki ana me te whakamahi ki te pa atu ki nga waikura kaha me nga mura ahi hei karo i te ahi, te pahūtanga ranei.
- Ka pa te kino ki te kiri, ki nga kanohi, ki te waahanga manawa, me mau nga taputapu whakamarumaru e tika ana penei i nga karapu, motiti, me nga taputapu whakamarumaru manawa e mahi ana.
- I te wa e whakamahi ana, e whakahaere ana ranei i te puhui, me mahi ki roto i te waahi pai te hau me te karo i te horohanga, i te horonga pokanoa ranei. I muri i te maimoatanga, me tino horoia te waahi kua poke.
