3-Bromo -5-iodobenzoic acid (CAS # 188815-32-9) Taw qhia
-Cov tsos mob: 3-Bromo-5-iodobenzoic acid yog dawb lossis daj daj crystalline khoom.
-Solubility: Nws tuaj yeem yaj ib nrab hauv cov kuab tshuaj, xws li cawv thiab ketones, tab sis nws cov solubility hauv dej yog tsawg.
-Melting point: Nws muaj qhov melting ntau dua, feem ntau ntawm 120-125 ° C.
-Cov khoom siv tshuaj: 3-Bromo-5-iodobenzoic acid yog cov kua qaub uas tsis muaj zog uas tuaj yeem tsim cov ntsev sib xws hauv cov kab mob alkaline.
Siv:
3-Bromo-5-iodobenzoic acid feem ntau yog siv rau hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj synthesis. Nws tuaj yeem siv los tsim cov tshuaj tiv thaiv kab mob xws li chloroquine. Tsis tas li ntawd, nws tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov organic sib txuas xws li dyes thiab tshuaj tua kab.
Txoj kev:
3-Bromo-5-iodobenzoic acid tuaj yeem npaj los ntawm chloroalkylation. Ua ntej, chloro compound yog tsim los ntawm cov tshuaj tiv thaiv ntawm O-iodobenzoic acid thiab tooj liab bromide, thiab tom qab ntawd nws hloov mus rau 3-Bromo-5-iodobenzoic acid los ntawm bromination.
Cov ntaub ntawv kev nyab xeeb:
3-Bromo-5-iodobenzoic acid feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm siv. Txawm li cas los xij, raws li tshuaj lom neeg, nws tseem txaus ntshai. Kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab. Yog li ntawd, hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes thiab tsom iav thaum siv. Nyob rau tib lub sijhawm, tsis txhob nqus nws cov plua plav lossis tshuaj. Nyob rau hauv tus txheej txheem ntawm kev cia thiab tuav, nws yuav tsum tau tswj kom zoo kom tsis txhob cia nrog flammable tshuaj, oxidants thiab lwm yam khoom. Nyob rau hauv rooj plaub ntawm kev sib tsoo, cov kev ntsuas tsim nyog yuav tsum tau coj los ntxuav thiab daws nrog nws. Hauv kev tuav cov tshuaj no, yuav tsum ua raws li cov txheej txheem kev nyab xeeb tsim nyog thiab kev taw qhia.
