Qhov sib txawv tseem ceeb ntawm methyl chloride thiab methylene chloride yog tias methyl chloride tshwm sim tsis muaj xim, tsis muaj ntxhiab tsw ntawm chav tsev kub, qhov methylene chloride tshwm sim ua kua tsis muaj xim, tsis muaj kuab lom nyob rau hauv chav tsev kub.
Methyl chloride thiab methylene chloride yog cov organic tebchaw tseem ceeb hauv kev lag luam. Methyl chloride los yog chloromethane yog cov organic compound uas muaj cov tshuaj formula CH3Cl, thaum methylene chloride los yog dichloromethane yog cov organic compound uas muaj cov tshuaj formula CH2Cl2.
Methyl Chloride (los yog chloromethane) yog dab tsi?
Methyl chloride lossis chloromethane yog cov organic compound uas muaj cov tshuaj formula CH3Cl. Nws tseem hu ua refrigerant 40, R-40, los yog HCC 40. Nws yog ib qho haloalkane uas tsis muaj xim, tsis muaj ntxhiab, flammable, thiab tshwm sim hauv lub xeev roj ntawm chav tsev kub. Cov tshuaj no yog ib qho tseem ceeb hauv kev lag luam chemistry, tab sis nws tsis tshua muaj tshwm sim hauv cov neeg siv khoom. Methyl chloride yog thawj zaug tsim los ntawm ib tug kws tshuaj Fabkis txoj nyob rau hauv 1835 los ntawm boiling ib tug sib tov ntawm methanol, sulfuric acid, thiab sodium chloride. Niaj hnub no, nws yog tsim los ntawm kev kho methanol nrog rau hydrochloric acid los yog hydrogen chloride.
Daim duab 01: Cov Qauv Tshuaj ntawm Methyl Chloride
Cov tshuaj no yog ib qho organohalogen ntau ntau uas yog ntuj lossis anthropogenic hauv huab cua. Cov pa roj muaj qhov tsw qab, tsw qab. Qee cov kab mob marine tuaj yeem tsim methyl chloride. Tsis tas li ntawd, cov nroj tsuag ntsev tuaj yeem tsim cov tshuaj no ib yam nkaus.
Methyl chloride compound muaj tetragonal geometry. Nws cov duab molecular yog tetrahedron. Tsis tas li ntawd, nws raug suav hais tias yog cov kab mob carcinogenic.
Methylene Chloride (los yog Dichloromethane) yog dab tsi?
Methylene chloride lossis dichloromethane yog cov organic compound uas muaj cov tshuaj formula CH2Cl2. Nws yog ib qho organochlorine compound, thiab peb tuaj yeem txhais tau tias nws yog DCM. Cov tshuaj no tshwm sim raws li cov kua tsis muaj xim tsis muaj xim uas muaj chloroform zoo li qab zib tsw. Dichloromethane feem ntau yog siv los ua cov kuab tshuaj. Cov kua no tsis yog miscible nrog dej txawm tias nws yog ib qho polar compound. Txawm li cas los xij, nws tuaj yeem sib xyaw nrog ntau lwm cov kuab tshuaj organic.
Daim duab 02: Methylene Chloride
Muaj qee qhov chaw ntawm dichloromethane, suav nrog cov chaw dej hiav txwv, macroalgae, cov av ntub dej, thiab cov roob hluav taws. Txawm li cas los xij, peb tuaj yeem pom tias feem ntau dichloromethane hauv ib puag ncig yog vim muaj kev lag luam emissions. Peb tuaj yeem tsim dichloromethane los ntawm kev kho chloromethane lossis methane nrog cov roj chlorine ntawm qhov kub thiab txias.
Qhov txawv ntawm Methyl Chloride thiab Methylene Chloride yog dab tsi?
Methyl chloride thiab methylene chloride yog cov khoom lag luam tseem ceeb hauv cov tebchaw. Methyl chloride los yog chloromethane yog cov organic compound uas muaj cov tshuaj formula CH3Cl. Methylene chloride los yog dichloromethane yog cov organic compound uas muaj cov tshuaj formula CH2Cl2. Qhov sib txawv tseem ceeb ntawm methyl chloride thiab methylene chloride yog tias methyl chloride tshwm sim tsis muaj xim, tsis muaj ntxhiab tsw ntawm chav sov, qhov methylene chloride tshwm sim ua kua tsis muaj xim, tsis muaj kuab lom nyob rau hauv chav tsev kub.
Cov hauv qab no qhia txog qhov sib txawv ntawm methyl chloride thiab methylene chloride hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Methyl Chloride vs Methylene Chloride
Methyl chloride thiab methylene chloride yog cov khoom lag luam tseem ceeb hauv cov tebchaw. Qhov sib txawv tseem ceeb ntawm methyl chloride thiab methylene chloride yog tias methyl chloride tshwm sim tsis muaj xim, tsis muaj ntxhiab tsw ntawm chav sov, thaum methylene chloride tshwm sim raws li cov kua tsis muaj xim, tsis muaj kuab paug ntawm chav tsev kub. Methyl chloride yog ib qho tseem ceeb raws li tshuaj loog hauv zos, ib qho tshuaj nruab nrab hauv kev tsim cov silicone polymer, hauv kev tsim tshuaj thiab lwm yam, whereas methylene chloride yog ib qho tseem ceeb hauv cov xim stripping, kev tsim tshuaj, kev tsim tshuaj pleev xim, ntxuav hlau, thiab degreasing.
