Taw qhia
Tom ntej: Methyl 6-chloronicotinate Cov hauv qab no yog cov lus qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv:
Zoo:
- Methyl 6-chloronicotinate yog cov kua tsis muaj xim nrog cov ntxhiab tsw.
- Insoluble hauv dej, tab sis soluble hauv cov kuab tshuaj organic xws li ethanol, acetone, thiab benzene.
- Nws yog ib qho muaj zog esterifying tus neeg sawv cev.
Siv:
- Hauv kev ua liaj ua teb, nws tuaj yeem siv ua tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
- Methyl 6-chloronicotinate feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm methyl nicotinate thiab thionyl chloride. Cov txheej txheem tshuaj tiv thaiv tuaj yeem catalyzed los ntawm sulfuryl chloride los tsim methyl 6-chloronicotinate thiab hydrogen sulfate.
Cov ntaub ntawv kev nyab xeeb:
- Methyl 6-chloronicotinate yog cov tshuaj lom thiab yuav tsum tau ceev faj.
- Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab kev ua pa thaum siv lossis tuav methyl 6-chloronicotinate. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum tsim nyog.
- Thaum lub sij hawm cia thiab kev thauj mus los, kev sib cuag nrog cov oxidants, muaj zog acids thiab cov hauv paus muaj zog yuav tsum zam.
