Taw qhia
N-trifluoroacetimidazole. Nws muaj cov khoom nram qab no:
1. Cov tsos mob: N-trifluoroacetamidazole yog cov xim tsis muaj xim crystalline.
2. Solubility: Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li ethanol, ethyl acetate thiab dimethylformamide, thiab lwm yam.
3. Stability: N-trifluoroacetamidazole muaj kev ruaj ntseg zoo rau cua sov thiab lub teeb.
N-trifluoroacetimidazole feem ntau yog siv los ntawm cov organic synthesis thiab feem ntau yog siv los ua hydrofluorate tsim reagent rau cov organic tebchaw. Nws tuaj yeem siv los tsim cov tshuaj sib txawv uas muaj pawg trifluoroacetyl, xws li ketones thiab cawv, enol ethers thiab esters.
Txoj kev npaj ntawm N-trifluoroacetamidazole yog cov hauv qab no:
1. Chlorinate trifluoroacetic acid los yog sodium fluoride yog reacted nrog imidazole kom tau cov khoom lag luam.
2. Trifluoroacetic anhydride yog reacted nrog imidazole nyob rau hauv acidic tej yam kev mob los tsim N-trifluoroacetylimidazole.
1. Hnav cov hnab looj tes tiv thaiv tsim nyog, tsom iav tiv thaiv thiab hnav khaub ncaws tiv thaiv thaum siv.
2. Tsis txhob nqus nws cov plua plav lossis vapors thiab xyuas kom meej tias qhov chaw ua haujlwm yog qhov cua zoo.
3. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag, yaug tam sim ntawd nrog dej txaus thiab nrhiav kev kho mob.
4. Khaws kom deb ntawm qhov hluav taws kub thiab oxidants thiab khaws cia thaum khaws cia.
