Taw qhia
2-Amino-5-bromotrifluorotoluene. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
2-Amino-5-bromotrifluorotoluene yog daj rau txiv kab ntxwv crystalline khoom. Nws muaj cov ntxhiab tsw zoo thiab yog insoluble hauv dej tab sis soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethyl sulfoxide.
Kev Siv: Nws kuj yog siv dav hauv kev ua liaj ua teb los ua tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
2-Amino-5-bromotrifluorotoluene feem ntau yog npaj los ntawm cov tshuaj synthesis. Ib txoj hauv kev uas siv los ua ke yog los ua 2-amino-5-bromotrifluorotoluenylsilane nrog sodium nitrite los ua ib qho nruab nrab, thiab tom qab ntawd desililicate kom tau txais cov khoom kawg.
Cov Lus Qhia Txog Kev Nyab Xeeb: Nws tuaj yeem ua rau khaus qhov muag, tawv nqaij, thiab ua pa. Lub sij hawm ntev los yog loj heev tuaj yeem ua rau tib neeg noj qab haus huv. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, looj tsom iav, thiab cov cuab yeej tiv thaiv ua pa yuav tsum hnav thaum ua haujlwm. Tsis tas li ntawd, nws yuav tsum tau muab cia rau hauv lub thawv airtight kom tsis txhob muaj kev sib cuag nrog cov khoom xws li oxidants thiab muaj zog acids. Yog tias tsim nyog, nws yuav tsum tau ua haujlwm nyob rau hauv qhov chaw muaj cua zoo thiab tsis txhob nqus nws cov vapors. Thaum siv lossis tuav cov khoom sib xyaw no, ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam.
