Taw qhia
2-Bromoheptafluoropane yog ib qho organic compound nrog cov tshuaj formula C3F7Br. Cov hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb ntawm cov khoom:
1. xwm:
-Cov tsos mob: tsis muaj xim tsis muaj roj
- Boiling point: txog 62-63 ° C
- Ceev: approx. 1.75 g / cm³
-Solubility: Yuav luag insoluble hauv dej, soluble hauv organic solvents
-Stability: Lub compound yog qhov ruaj khov ntawm chav tsev kub, tab sis tuaj yeem decompose ntawm qhov kub thiab txias los yog thaum sib cuag nrog cov oxidants muaj zog
2. siv:
- 2-Bromoheptafluoropropane muaj peev xwm ua kom puas ozone tsawg, yog li nws tau dav siv los ua cov tub yees los hloov Freon.
-Nws kuj tseem siv tau los ua ib hom kev tu tus neeg saib xyuas, xws li tus neeg saib xyuas qhov chaw hlau thiab tus neeg saib xyuas semiconductor.
3. Txoj kev npaj:
-Feem ntau 2-Bromoheptafluoropropane tuaj yeem tau txais los ntawm kev ua haujlwm 1,1,1,2,3,4,4,5, nrog triethylamine lossis lwm cov hauv paus.
4. Cov ntaub ntawv kev nyab xeeb:
-2-Bromoheptafluoropane yog cov roj hluav taws xob uas tuaj yeem ua rau kub hnyiab thiab tawg ntawm qhov kub thiab txias los yog muaj hluav taws kub. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj hluav taws kub thiab tsis txhob kub ib puag ncig thaum siv los yog cia.
-Thaum siv, tsis txhob nqus cov pa los yog vapor ntawm cov khoom thiab xyuas kom meej tias muaj qhov cua zoo.
-Thaum nyob rau hauv kev sib cuag nrog hluav taws kub los yog kub siab, tej zaum yuav muaj roj toxic gas los yog pa luam yeeb, yog li yuav tsum tau kev tiv thaiv tsim nyog thaum tuav.
-Vim nws cov khoom siv tshuaj, 2-Bromoheptafluoropropane yog tshuaj lom rau ib puag ncig thiab kab mob, thiab tej zaum yuav ua rau muaj kuab paug rau hauv dej.
Vim tias qhov no yog cov tshuaj lom neeg, cov kev khiav hauj lwm kev nyab xeeb thiab cov kev cai yuav tsum tau ua raws li thaum siv los yog tuav, thiab yuav tsum tau ua raws li kev ceev faj kom raug. Ua ntej siv, nws yog qhov zoo tshaj plaws los sab laj cov ntaub ntawv kev nyab xeeb uas cuam tshuam los yog sab laj tus kws tshaj lij kom paub meej ntxiv thiab cov ntaub ntawv raug.
