Methylene Chloride Ua li cas

Kev tsim cov methylene chloride muaj ob peb kauj ruam. Cov txheej txheem feem ntau yog cov tshuaj tiv thaiv ntawm methane thiab chlorine nyob rau hauv lub xub ntiag ntawm UV teeb los yog kub kub. Cov tshuaj tiv thaiv no tsim cov tshuaj chloromethane, uas tom qab ntawd ua rau cov roj chlorine los ua cov tshuaj methylene chloride.

Lwm txoj kev ntawm kev tsim khoom muaj xws li cov tshuaj tiv thaiv ntawm methane nrog hydrochloric acid, uas yields methyl chloride. Tom qab ntawd methyl chloride yog reacted nrog chlorine gas los tsim methylene chloride.

Methylene chloride yog cov kuab tshuaj muaj txiaj ntsig thiab muaj txiaj ntsig zoo, ua rau nws muaj txiaj ntsig zoo hauv ntau cov ntawv thov kev lag luam. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, cov tshuaj methylene chloride tau pom tias muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig. Txawm li cas los xij, tseem muaj kev siv zog mus nrhiav kev nyab xeeb dua thiab txhim kho kev tsim khoom thiab tuav cov tshuaj tseem ceeb no.

Hauv kev xaus, kev tsim cov methylene chloride koom nrog ntau cov kauj ruam uas ua rau cov khoom muaj txiaj ntsig zoo siv rau hauv ntau daim ntawv thov kev lag luam.
