Thawj npaj hauv 1839 los ntawm cov tshuaj tiv thaiv ntawm chloroform nrog cov tshuaj chlorine, carbon tetrachloride yog tsim los ntawm cov tshuaj 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.
Leej twg nrhiav tau tetrachloride?
Carbon tetrachloride yog Ameslikas tsim los ntawm tus kws tshuaj Fab Kis Fab Kis Henri Victor Regnault xyoo 1839 los ntawm cov tshuaj tiv thaiv chloroform nrog cov tshuaj chlorine, tab sis tam sim no nws yog tsim los ntawm methane: CH 4 + 4 Cl2 → CCl4 + 4 HCl.
carbon tetrachloride yog dab tsi thiab thaum twg nws siv?
Yav dhau los, carbon tetrachloride tau siv dav ua cov kua dej huv(hauv kev lag luam thiab cov chaw ntxuav qhuav ua cov tshuaj degreasing, thiab hauv tsev neeg ua cov khoom tshem tawm cov khaub ncaws, rooj tog, thiab ntaub pua plag). Cov pa roj carbon tetrachloride kuj tau siv rau hauv cov tshuaj tua hluav taws thiab ua cov fumigant tua kab hauv nplej.
keeb kwm ntawm carbon tetrachloride yog dab tsi?
Layman piav qhia: Carbon tetrachloride tau npaj thawj zaug xyoo 1839 Nws tau tshawb pom los ntawm German-yug Fabkis tus kws tshawb fawb Henri Victor Regnault thaum nws ua haujlwm nrog ether / chlorine cov tshuaj tiv thaiv. Carbon tetrachloride yog ib qho ntshiab, hnyav, tshuaj lom, tsis muaj kuab lom nrog cov ntxhiab tsw muaj zog.
carbon tetrachloride ua li cas?
Carbon tetrachloride yog cov tshuaj tsim thiab tsis tshwm sim hauv ib puag ncig. Nws yog tsim los ntawm chlorination ntawm ntau yam tsis muaj zog molecular hnyav hydrocarbons xws li carbon disulfide, methane, ethane, propane, los yog ethylene dichloridethiab kuj los ntawm thermal chlorination ntawm methyl chloride.

Thaum twg tus neeg tsim khoom tsim tawm?
Raws li lwm qhov chaw, tus onager tau tsim nyob rau hauv tim Nkij teb chaws xyoo 385 BCE los ntawm tus kws kho tsheb Ammianus Marcellinus (Robert M. Jurga). Lub zog jerk thiab lub tshuab nqa ntawm txhua qhov kev txhaj tshuaj, Loos hu ua "
Thaum twg ntoo nres sequestering carbon?
Txoj hav zoov sequester lossis khaws cov pa roj carbon feem ntau hauv trees thiab av. Thaum lawv tsuas yog rub cov pa roj carbon monoxide tawm ntawm huab cua-ua rau lawv lub dab dej-lawv kuj tso cov pa roj carbon dioxide. Qhov no tshwm sim ib txwm muaj, xws li thaum tsob ntoo tuag thiab decomposed (yog li tso carbon dioxide, methane, thiab lwm yam gases) .
Leej twg tsim cov ntawv tsis muaj carbon?
Nws tau tsim los ntawm kws tshuaj Lowell Schleicher thiab Barry Green, ua lwm yam rau cov ntawv carbon thiab qee zaum misidentified xws li. Kev luam cov pa roj carbonless muab lwm txoj hauv kev siv cov pa luam yeeb . Thaum twg yog carbonless ntawv tsim?
Qhov twg thiab thaum twg yog qhov chaw ua haujlwm ntawm thawj kws kho mob kws kho mob tau tsim?
Nyob rau hauv 44 BC, ntawm thawj qhov keeb kwm ntawm kev tshuaj ntsuam xyuas kab mob tshwm sim tam sim ntawd tom qab lub sleighing ntawm Julius Caesar los ntawm nws cov neeg koom tes. Tus kws tshuaj xyuas lub sijhawm ntawd xaus lus tias ntawm 23 qhov txhab pom ntawm lub cev tsuas yog ib tus neeg tuag xwb .
Thaum twg tsim khoom tsim?
Thawj qhov kev hloov pauv loj hauv kev tsim khoom lag luam tau los thaum lub sijhawm peb tam sim no hu ua Industrial Revolution. Qhov no yog kev hloov pauv uas tshwm sim hauv 18th caug xyoo qhov twg, tsis yog cov khoom tsim los ntawm tes, cov txheej txheem tau tsim tawm uas tso cai rau cov khoom tsim los ntawm cov tshuab .
