Chaw tsim tshuaj paus uas tus methylene chloride CAS: 75-09-2 Featured Duab

Cov lus piav qhia luv luv:

Methylene chloride yog ib tug compound minets nyob rau hauv methane molecules, thiab molecular ch2cules yog tsis muaj xim, pob tshab, cov kua kub. Nws muaj qhov tsis hnov tsw thiab qab zib zoo sib xws rau Etaws. Nws tsis hlawv. Methylene chloride yog soluble me ntsis hauv dej, thiab nws yaj nrog feem ntau siv cov organic kuab tshuaj. Nws kuj tseem tuaj yeem yaj nyob rau hauv ib qho kev faib ua feem nrog lwm cov chlorine-muaj cov kuab tshuaj, ethanol, thiab n-di metamimamamide. Methylene chloride yog qhov nyuaj kom yaj hauv cov kua amonia nyob rau hauv chav sov, uas tuaj yeem sai, tororine, cycamine, acetylcetate. Lub Ntu HTTSICE yog 1.3266 (20/4 ° C). Lub ntsiab lus melting -95.1 ° C. Boiling taw tes 40 ° C. Tag nrho cov kuab tshuaj pleev plab, thiab tuaj yeem siv tshuaj loog hauv zos, thiab tua hluav taws. Qhov tshwm sim kev sib xyaw ua ke yog 640 ° C. Decoction (20 ° C) 0.43Mpa a. Cov neeg siv hluav taws xob ua haujlwm ND (20 ° C) 1.4244. Qhov kub tseem ceeb yog 237 ° C, thiab tseem ceeb yog 6.0795MPA. HCL thiab ib puag ncig ntawm lub teeb yog tsim kom tom qab tov kev daws teeb meem, thiab cov dej yog rhuab ntev los ua kom tsim nyog los ua cov formaldehyde thiab hc. Cov chloride ntxiv, Chcl3 thiab CCL4 tuaj yeem tau txais.

Cov ntawv thov ntawm Methylene chloride

Methylene chloride (DCM) muaj qhov zoo ntawm cov thwj solubility thiab cov tshuaj lom tsawg. Nws yog siv los tsim cov yeeb yaj kiab zoo thiab polycarbonate, thiab tus so yog siv cov kuab tshuaj, roj av tso quav, de -kas tus neeg sawv cev, tus neeg saib xyuas lacquer. Dichhloromethane yog cov kua tsis muaj xim, uas yog siv los ua cov tshuaj tiv thaiv nruab nrab los npaj ammonia penicillin, hydroxycin thiab pioneecin, thiab lwm yam; Organic hluavtaws cov tshuaj tua cov neeg sawv cev, polyurethane thiab lwm yam ua npuas dej yas ntau lawm rau cov neeg sawv cev ua npuas ncauj thiab cov neeg sawv cev hlau. Dichhloromethanousane feem ntau yog siv nyob rau hauv kev ua yeeb yaj kiab ntawm zaj duab xis tsim thiab cov kws tshuaj hauv Suav teb. Ntawm lawv, kev noj ntawm zaj duab xis txheej txheem rau 50% ntawm tag nrho cov nyiaj, kev noj tshuaj rau kev tu 20% ntawm kev siv tshuaj lom neeg, thiab lwm yam nyiaj rau 10%. Dichhloromethans tseem siv rau hauv cov tshuab tub yees rau cov tub yees, tab sis nws muaj peev xwm tsim cov teeb pom kev zoo thaum hu cov khoom hluav taws lossis hlawv cov khoom. Nyob rau hauv rooj plaub noo, hydrolyzed hydrogen chloride tuaj yeem siv los txhawb hydrogen Chloride, thiab lub teeb tseem tuaj yeem txhawb nqa hydrolysis thiab txhim kho cov hlau corrosive. Siv rau cua txias ntawm cov nplej fumigation thiab qis -voltage khov thiab cua-khoom siv. Hauv kev tsim cov polyether -tpepe tso zis alkane yas, nws yog siv los ua cov neeg sawv cev ua npuas ncauj, nrog rau cov neeg sawv cev ua npuas ncauj kom huv si plastics. Dichhloromethans tseem siv los ua cov tshuaj rau kas fes lub cev qhuav dej. Cov kas fes ua ntej ua noj kom yaj cov paffeine thiab floats nyob rau saum npoo, thiab tom qab ntawd siv Dichhloromethane mus tshem caffeine.
1. Nws yog qhov tsis -qhoiling dot tsawg -boiling dot cov kuab tshuaj memurce, huab cua -soluble thiab cov tshuaj tua kab mob, thiab cov kuab tshuaj hauv cov vitamin ntau lawm.
2. Digerine yog cov khoom siv ru tsim los ntawm sterilizers azoxazole thiab mimozole, thiab nws kuj yog cov kuab tshuaj zoo.
3. Ntxiv rau cov organic hluavtaws hluavtaws, cov khoom no tseem muaj dav ua lub cev ua kom huv, cov tshuaj tua kab mob roj, thiab cov chav kawm hlau, thiab cov hlau sib dhos, thiab cov hlau sib txuas thiab hlau cov chav kawm tshuaj lom nyuj rau elux thiab decapyles. Tsis tas li ntawd, nws tseem siv rau cov khaub thuas thiab qis -voltage khov thiab cua-khoom siv. Nyob rau hauv kev tsim cov polyether -tpe tso zis alkane yas, nws yog siv los ua cov neeg sawv cev ua npuas ncauj, thiab ua npuas dej kom huv si kom huv si.
4. Extract hnyav. Yog tias nws siv los rho cov pa kas fes hauv taum kas fes. Nws kuj yog siv los ua cov kuab tshuaj rau toj, cov tshuaj tsw qab roj, thiab lwm yam.
5. Rau cov kuab tshuaj, nws tseem siv rau cov synthic synthesis.
6. Hnyav rau Resin thiab kev lag luam yas. Nws yog dav siv nyob rau hauv kev lag luam xws li tshuaj, plastics thiab zaj duab xis.
