Tom ntej: Methyl 3-bromo-5-iodobenzoate (CAS # 188813-07-2)
Methyl 3-bromo-5-iodobenzoate (CAS # 188813-07-2) Taw qhia
1. Cov tsos: Xim tsis muaj xim rau daj ntseg daj crystalline khoom.
2. Melting Point: txog 50-52 ℃.
3. Kub taw tes: Txog 265-268 ℃.
4. Solubility: Soluble nyob rau hauv organic solvents xws li ethanol, ether, me ntsis soluble nyob rau hauv dej.
Siv:
1. BIPM feem ntau yog siv rau hauv cov tshuaj esterification hauv cov organic synthesis.
2. Nws kuj tseem tuaj yeem siv los ua esterification reagent lossis reagent intermediate rau cov tshuaj tiv thaiv ntxiv hauv cov organic synthesis.
Txoj kev:
Lub synthesis ntawm BIPM feem ntau tau los ntawm reacting 3-bromo-5-iodobenzoic acid nrog methanol. Thaum lub sij hawm cov tshuaj tiv thaiv, feem ntau siv tej yam kev mob, feem ntau siv lub hauv paus yog sodium carbonate, thiab cov tshuaj tiv thaiv yog feem ntau nqa tawm nyob rau hauv chav tsev kub.
Cov ntaub ntawv kev nyab xeeb:
1. BIPM yog ib qho organic halogen compound, uas muaj qee yam toxicity thiab yuav tsum tau ua tib zoo siv.
2. Thaum lub sijhawm ua haujlwm, hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws hauv chav kuaj.
3. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag, xws li kev sib chwv tsis sib haum, yuav tsum tam sim ntawd yaug nrog dej kom ntau, thiab nrhiav kev pab kho mob.
4. Thaum tuav thiab khaws cia, kev sib cuag nrog cov oxidants muaj zog thiab cov cua sov yuav tsum raug zam kom tsis txhob muaj kev phom sij txaus ntshai.
Ua ntej siv lossis ua haujlwm BIPM, nco ntsoov ua tib zoo nyeem thiab nkag siab txog cov ntaub ntawv kev nyab xeeb uas cuam tshuam los xyuas kom muaj kev nyab xeeb ntawm cov khoom siv.
