Thawj npaj xyoo 1839 los ntawm cov tshuaj tiv thaiv ntawm chloroform nrog cov tshuaj chlorine , carbon tetrachloride yog tsim los ntawm cov tshuaj tiv thaiv chlorine nrog carbon disulfide carbon disulfide Carbon disulfide ( CS 2), tseem hu ua Carbon Bisulfide, tsis muaj xim, muaj kuab lom, muaj kuab paug thiab nplaim taws ua kua tshuaj lom neeg, ntau cov khoom siv hauv kev tsim cov viscose rayon, cellophane., thiab carbon tetrachloride; Cov khoom me me yog siv rau hauv cov txheej txheem tshem tawm cov kuab tshuaj los yog hloov mus rau hauv … https://www.britannica.com › science › carbon-disulfide

los yog nrog methane.
Yuav ua li cas daim ntawv cog lus ntawm CCl4 tshwm sim?
CCl4 muaj covalent bondingCov pa roj carbon muaj plaub lub tshuab hluav taws xob hauv nws lub plhaub valence thiab sib koom nrog plaub lub chlorine atoms los tsim cov pa roj carbon tetrachloride molecule. Cov no muaj vander waals intermolecular zog ntawm attraction. Lawv yog tib lub zog txaus nyiam nyob hauv cov tebchaw uas tsis muaj polar.
CCl4 nyob qhov twg?
CCl4 tsis tshwm sim, tab sis tau raug tso tawm rau ib puag ncig los ntawm tib neeg kev ua ub no. Vim qhov kev tso tawm yav dhau los thiab tam sim no, CCl 4 tseem pom muaj nyob hauv huab cua, dej, thiab av , tab sis nyob rau theem tom qab qis heev. Cov pej xeem Meskas tuaj yeem raug CCl4 los ntawm huab cua.
Ccl4 siv dab tsi?
Carbon tetrachloride yog siv rau hauv ntxuav qhuav, tshem tawm cov roj ntawm cov hlauNws yog siv los tsim cov tub yees thiab aerosol propellants. Nws yog ib qho carcinogen, nqus los yog nqus tau los ntawm nws ua rau lub hlwb, daim siab, ob lub raum, thiab qee zaum txawm ua rau tuag taus. Nws yog siv nyob rau hauv proton NMR spectroscopy.
Tetrachloromethane siv rau dab tsi?
Tetrachloromethane yog cov kuab tshuaj muaj txiaj ntsig hauv kev lag luam tshuaj thiab siv rau ntxuav tshuab thiab khoom siv hluav taws xob. Nws kuj tseem siv tau rau hauv kev tsim cov khoom siv tshuaj.
