Cov txheej txheem twg txhawb nqa monochlorination? Pib cov tshuaj tiv thaiv nrog ntau tshaj ntawm methane thiab ntau tshaj ntawm chlorine . Thaum cov tshuaj tiv thaiv dhau lawm, yuav muaj me me ntawm methane thiab ntau dhau ntawm chloromethane chloromethane Chloromethane, tseem hu ua methyl chloride, Refrigerant-40, R-40 lossis HCC 40, yog cov organic compound nrog cov tshuaj formulaCH 3Cl. Ib qho ntawm cov haloalkanes, nws yog ib qho tsis muaj xim, tsis muaj ntxhiab, flammable gas. Methyl chloride yog ib qho tseem ceeb reagent nyob rau hauv industrial chemistry, txawm hais tias nws tsis tshua muaj nyob rau hauv cov neeg siv khoom. https://en.wikipedia.org › wiki › Chloromethane

. Cov no tuaj yeem sib cais tau yooj yim vim lawv cov ntsiab lus sib txawv.
Yuav ua li cas ntawm cov txheej txheem hauv qab no cuam tshuam nrog chlorination ntawm methane?
Thaum chlorine reacts nrog methane nyob rau hauv lub xub ntiag ntawm tshav ntuj, nws tsim Chloromethane. Cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv kab mob xws li. ib zaug nws pib nws tseem mus ntxiv. Nws yog pib los ntawm UV-rays. Tom qab ntawd lawv rhuav tshem kev sib raug zoo ntawm cov tshuaj chlorine molecules thiab tsim cov tshuaj dawb chlorine radicals uas muaj zog heev.
Muaj pes tsawg cov khoom lag luam Monochlorination ua tau?
Tag nrho kaum plaub cov khoom lag luam monochlorinated tuaj yeem tau los ntawm tag nrho cov isomeric alkanes uas muaj cov mis C5H10 (tsis suav nrog stereoisomers).
Dab tsi yog qhov txheej txheem ntawm chlorination?
Nyobsaw mechanism yog raws li nram no, siv cov chlorination ntawm methane raws li ib tug qauv piv txwv: 1. Initiation: Splitting los yog homolysis ntawm ib tug chlorine molecule los ua ob chlorine atoms, pib los ntawm ultraviolet hluav taws xob los yog hnub ci. Ib qho chlorine atom muaj ib qho hluav taws xob tsis sib xws thiab ua raws li cov dawb radical.
Vim li cas chlorination ntawm methane tseem ceeb?
Alkanes (qhov tseem ceeb tshaj plaws ntawm tag nrho cov organic tebchaw) tau txais cov tshuaj tiv thaiv tsawg heev. Cov tshuaj tiv thaiv no tseem ceeb heev hauv cov organic chemistry vim nws qhib lub qhov rooj rau cov tshuaj tiv thaiv ntxiv. …
