Methyl 3-bromo-5-iodobenzoate (CAS# 188813-07-2)
Methyl 3-bromo-5-iodobenzoate (CAS# 188813-07-2) Chiyambi
1. Maonekedwe: Opanda mtundu mpaka wotumbululuka wachikasu wakristalo wolimba.
2. Malo osungunuka: pafupifupi 50-52 ℃.
3. Malo otentha: Pafupifupi 265-268 ℃.
4. Kusungunuka: Kusungunuka mu zosungunulira organic monga ethanol, etha, sungunuka pang'ono m'madzi.
Gwiritsani ntchito:
1. BIPM imagwiritsidwa ntchito kwambiri popanga esterification mu organic synthesis.
2. Angagwiritsidwenso ntchito ngati reagent esterification kapena reagent wapakatikati zina zimachitikira mu kaphatikizidwe organic.
Njira:
Kaphatikizidwe wa BIPM nthawi zambiri amapezeka pochita 3-bromo-5-iodobenzoic acid ndi methanol. Poyankha, zinthu zoyambira zimagwiritsidwa ntchito nthawi zambiri, maziko omwe amagwiritsidwa ntchito kwambiri ndi sodium carbonate, ndipo zomwe zimachitika nthawi zambiri zimachitika kutentha.
Zambiri Zachitetezo:
1. BIPM ndi organic halogen compound, yomwe ili ndi poizoni wina ndipo iyenera kugwiritsidwa ntchito mosamala.
2. Pamene mukugwira ntchito, valani zida zodzitetezera zoyenera monga magolovesi oteteza, magalasi ndi zovala za labotale.
3. Pewani kukhudzana ndi khungu ndi maso, monga kukhudza mwangozi, muyenera kuchapa nthawi yomweyo ndi madzi ambiri, ndikupempha thandizo lachipatala.
4. Pogwira ndi kusunga, kukhudzana ndi ma oxide amphamvu ndi magwero a kutentha kuyenera kupewedwa kuti mupewe zoopsa.
Musanagwiritse ntchito kapena kugwiritsa ntchito BIPM, onetsetsani kuti mwawerenga mosamala ndikumvetsetsa masamba otetezedwa kuti muwonetsetse kugwiritsa ntchito kotetezedwa.
