1,2-Dichloroethane: Ib qho tshuaj lom neeg siv tau ntau yam
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam tshuaj lom neeg, kev siv 1,2-dichloroethane tseem ceeb yog ua cov khoom siv raw rau kev tsim cov vinyl chloride. Vinyl chloride yog ib qho tseem ceeb monomer siv los tsim cov polyvinyl chloride (PVC), ib qho yas siv dav hauv kev tsim kho, cov kav dej, cov khoom siv rwb thaiv tsev cable, thiab cov ntaub ntawv ntim khoom. Tsis tas li ntawd, 1,2-dichloroethane tuaj yeem hloov pauv mus rau acetylene los ntawm dehydrochlorination. Acetylene yog ib qho tseem ceeb nruab nrab rau kev tsim cov organic, siv rau hauv kev tsim ntau yam khoom siv tshuaj xws li acetaldehyde, acetic acid, thiab chloroprene roj hmab.
Hauv cov tshuaj yaj, 1,2-dichloroethane yog cov tshuaj yaj organic zoo uas muaj peev xwm yaj ntau yam organic compounds thiab polymers. Nws feem ntau siv rau kev ntxuav thiab tshem cov roj ntawm cov hlau, tshwj xeeb tshaj yog hauv kev lag luam hluav taws xob thiab kev ua haujlwm kho tshuab. Tsis tas li ntawd, 1,2-dichloroethane yog siv rau kev tshem tawm xim thiab txheej, nrog rau kev ntxuav cov khoom siv luam ntawv hauv kev lag luam luam ntawv.
Hauv kev lag luam tshuaj tua kab thiab tshuaj tsw qab, 1,2-dichloroethane yog siv ua ib qho nruab nrab. Nws tuaj yeem siv los ua ntau yam tshuaj tua kab, xws li tshuaj tua kab thiab tshuaj tua kab, uas siv dav hauv kev ua liaj ua teb. Tsis tas li ntawd, 1,2-dichloroethane tuaj yeem siv los tsim cov tshuaj tsw qab thiab cov khoom qab, siv dav hauv kev lag luam zaub mov thiab tshuaj pleev ib ce.
Hauv kev kho dej, cov khoom siv ntawm 1,2-dichloroethane, xws li chlorinated polyethylene, yog siv los tsim cov khoom siv tsis muaj dej thiab tiv taus xeb. Cov ntaub ntawv no siv dav hauv kev kho dej rau cov tsev thiab cov khoom siv hauv kev lag luam, tiv thaiv dej nkag thiab xeb tau zoo.
Txawm hais tias nws siv tau rau ntau yam kev lag luam, 1,2-dichloroethane muaj tshuaj lom, thiab nws siv yuav tsum ua raws li cov cai kev nyab xeeb. Kev tsim khoom hauv kev lag luam feem ntau siv cov tshuab kaw kom txo nws qhov kev hloov pauv thiab muaj cov cua thiab cov pa tawm zoo los tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm thiab kev nyab xeeb ntawm ib puag ncig. Nrog rau kev paub txog ib puag ncig ntau ntxiv, cov txheej txheem tsim khoom ntawm 1,2-dichloroethane kuj tseem raug kho kom zoo dua los txo nws cov kev cuam tshuam rau ib puag ncig.
