Taw qhia
Methyl 4,6-dichloronotinic acid. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: Methyl 4,6-dichloronotinate yog xim tsis muaj xim rau lub teeb daj.
- Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li cawv, ethers, thiab ketones, thiab insoluble hauv dej.
- Odor: Nws muaj pungent tsw.
Siv:
- Cov tshuaj tua kab nruab nrab: Methyl 4,6-dichloronotinic acid feem ntau yog siv los ua cov tshuaj tua kab nruab nrab hauv kev sib txuas ntawm ntau yam tshuaj tua kab, tshuaj tua kab thiab fungicides.
- Chemical synthesis: Nws kuj tseem siv tau los ua cov khoom siv tseem ceeb hauv cov organic synthesis, xws li cov synthesis ntawm esters, amides thiab heterocyclic compounds.
Txoj kev:
- Methyl 4,6-dichloronicotinate tuaj yeem tau txais los ntawm chlorination ntawm nicotinyl chloride (3-chloropyridine-4-formyl chloride). Cov kauj ruam tshwj xeeb suav nrog reacting nicotinyl chloride nrog methanol los tsim methyl 4,6-dichloronicotinate.
Cov ntaub ntawv kev nyab xeeb:
- Ceeb toom kev pheej hmoo: Methyl 4,6-dichloronicotinate yog ib qho organochlorine compound uas muaj peev xwm toxicity. Kev kis tau ntev, nqus tau, lossis sib cuag ntawm daim tawv nqaij tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
- Kev tiv thaiv: Hnav cov hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab khaub ncaws tiv thaiv thaum siv lossis tiv tauj.
- Cia ceev faj: Nws yuav tsum muab cia rau hauv qhov chaw qhuav, txias, zoo-ventilated. Tsis txhob sib cuag nrog oxidants, acids thiab lwm yam khoom.
