Taw qhia
4-Methyl-2-nitroaniline, tseem hu ua methyl daj, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: Methyl daj yog daj muaju los yog crystalline hmoov.
- Solubility: Methyl daj yuav luag insoluble hauv dej, tab sis soluble nyob rau hauv ntau cov organic solvents xws li cawv, ethers, thiab benzene.
Siv:
- Chemical intermediates: Methyl daj feem ntau yog siv los ua ib qho tseem ceeb nruab nrab hauv kev sib txuas ntawm cov xim, xim, fluorescents thiab cov khoom siv optoelectronic organic.
- Biomarkers: Methyl daj tuaj yeem siv los ua fluorescent labeler rau cov hlwb thiab biomolecules, uas yog siv rau hauv kev sim tshuaj lom neeg thiab kev kho mob.
- Enamel thiab ceramic pigments: Methyl daj kuj tuaj yeem siv los ua cov xim rau enamels thiab ceramics.
Txoj kev:
- Methyl daj yog npaj nyob rau hauv ntau txoj kev, thiab ib tug ntawm cov feem ntau txoj kev yog synthesize nws los ntawm methylation ntawm nitroaniline. Qhov no tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm methanol thiab thionyl chloride nyob rau hauv muaj cov kua qaub catalyst.
Cov ntaub ntawv kev nyab xeeb:
- Methyl daj yog cov tshuaj lom neeg uas ua rau khaus thiab ua rau muaj kev phom sij rau tib neeg thiab ib puag ncig.
- Cov khoom siv tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav thiab hnav ris tsho yuav tsum tau ua thaum ua haujlwm.
- Tsis txhob nqus pa, tiv nrog daim tawv nqaij thiab qhov muag, tsis txhob noj, thiab siv qhov cua kom tsim nyog yog tias tsim nyog.
- Thaum khaws cia thiab tuav cov tshuaj methyl daj, ua raws li cov txheej txheem kev nyab xeeb thiab cov kev cai.
