Taw qhia
Dimethoxyaniline (N-methylaniline) yog cov organic compound. Nws yog ib qho organic amine nrog cov cawv-amine xwm thiab pKa ntawm 4.64. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm dimethoxyaniline:
Zoo:
- Cov tsos mob: Dimethoxyaniline yog xim tsis muaj xim rau lub teeb daj.
- Solubility: Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li cawv, ethers, thiab chlorinated hydrocarbons.
- Toxicity: Nws yog ib yam tshuaj lom, thiab raug los yog nqus tau cov pa ntau los yog kua yuav ua rau muaj kev phom sij rau kev noj qab haus huv.
Siv:
- Dimethoxyaniline feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.
- Nws kuj tseem siv tau los ua ib qho catalyst ntxiv rau cov tshuaj tiv thaiv kab mob los pab txhawb qee yam tshuaj tiv thaiv.
- Lub reactivity ntawm dimethoxyaniline nrog rau lwm cov tebchaw, nws cov tshuaj tiv thaiv nrog carbamate thiab amide tebchaw ua ib tug tseem ceeb kauj ruam nyob rau hauv synthesis ntawm tshiab compounds.
Txoj kev:
- Dimethoxyaniline tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm aniline thiab methanol. Cov tshuaj tiv thaiv nyob rau hauv acidic tej yam kev mob, xws li kev siv cov hydrochloric acid los yog sulfuric acid raws li catalysts, yuav pab tau cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
- Lemonaniline yog khaus rau ntawm daim tawv nqaij thiab ob lub qhov muag thiab ua rau muaj kev phom sij rau lub ntsws thiab plab hnyuv.
- Kev ceev faj tsim nyog xws li hnav cov hnab looj tes tiv thaiv, tsom iav, thiab cov khaub ncaws tiv thaiv yuav tsum tau siv thaum siv dimethoxyaniline kom ntseeg tau tias muaj cua zoo hauv kev sim.
- Thaum khaws cia thiab tuav bimethoxyaniline, tsis txhob sib cuag nrog cov oxidants muaj zog thiab cov khoom siv hluav taws xob, thiab khaws cia rau hauv qhov chaw txias, qhov cua thiab qhuav.
