Taw qhia
4-Fluoroaniline yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 4-Fluoroaniline yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw zoo li ammonia.
- Solubility: 4-Fluoroaniline yog soluble hauv cov kuab tshuaj organic xws li benzene, ethyl acetate thiab carbon disulfide. Nws solubility qis dua hauv dej.
Siv:
- 4-Fluoroaniline yog dav siv nyob rau hauv thaj tsam ntawm cov organic synthesis thiab feem ntau yog siv los ua raw khoom los yog nruab nrab.
- 4-Fluoroaniline kuj tuaj yeem siv rau hauv electrochemical thiab tshuaj ntsuam xyuas.
Txoj kev:
- Muaj ntau txoj hauv kev los npaj 4-fluoroaniline. Ib txoj hauv kev yog ua rau nitrobenzene nrog sodium fluorohydrochloride kom tau fluoronitrobenzene, uas tom qab ntawd hloov mus rau 4-fluoroaniline los ntawm kev txo cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
- 4-Fluoroaniline ua rau khaus thiab tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa puas. Yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag thaum tuav.
- Nws kuj yog cov khoom siv hluav taws xob, tsis txhob sib cuag nrog cov nplaim taws qhib thiab kub siab.
- Kev saib xyuas yuav tsum tau ua kom siv cov khoom pov thawj tawg thiab ua kom muaj cua zoo thaum khaws cia thiab siv.
- Thaum tuav 4-fluoroaniline, cov txheej txheem kuaj tsim nyog thiab kev ntsuas kev nyab xeeb yuav tsum ua raws.
Siv ceev faj thaum siv 4-fluoroaniline lossis lwm yam tshuaj sib txuas thiab ua raws li kev soj ntsuam lossis cov chaw tsim khoom cov lus qhia kev nyab xeeb.
