Tuam Tshoj Tus Nqi Zoo Methylene Chloride CAS: 75-09-2

piav qhia luv luv:

Methylene Chloride yog ib tug compound generated los ntawm ob hydrogen atoms nyob rau hauv methane molecules, thiab molecular CH2CL2.Methylene Chloride yog xim tsis muaj xim, pob tshab, hnyav, thiab volatile kua.Nws muaj ntxhiab tsw thiab qab zib zoo ib yam li ether.Nws tsis hlawv.Methylene Chloride yog me ntsis soluble hauv dej, thiab nws dissolves nrog feem ntau siv cov kuab tshuaj organic.Nws tseem tuaj yeem yaj hauv ib qho kev faib ua feem nrog lwm cov tshuaj chlorine-muaj cov kuab tshuaj, ether, ethanol, thiab N-di metamimamamide.Methylene Chloride yog qhov nyuaj rau yaj hauv cov kua ammonia ntawm chav tsev kub, uas tuaj yeem yaj sai sai hauv phenol, aldehyde, ketone, methamphetamine, triathrin, tororine, cycamine, acetylcetate.Phase Chemicalbook yog 1.3266 (20/4 ° C).Lub melting point -95.1 ° C. Boiling point 40 ° C. Tag nrho cov qis-boiling point solvents feem ntau yog siv los hloov flammable petroleum ether, ether, thiab lwm yam., thiab yuav siv tau raws li ib tug tshuaj loog hauv zos, refrigerant thiab tua hluav taws.Lub spontaneous combustion point yog 640 ° C. Decoction (20 ° C) 0.43MPa · s.Lub refractive index nd (20 ° C) 1.4244.Qhov ntsuas kub tseem ceeb yog 237 ° C, thiab lub siab tseem ceeb yog 6.0795MPa.HCL thiab cov cim ntawm lub teeb yog tsim tom qab thermal tov, thiab cov dej yog rhuab rau lub sij hawm ntev los tsim formaldehyde thiab HCL.Ntxiv chloride, CHCL3 thiab CCL4 tuaj yeem tau.

Kev siv ntawm Methylene Chloride

Methylene Chloride (DCM) muaj qhov zoo ntawm solubility muaj zog thiab tsis muaj tshuaj lom.Nws yog siv los tsim cov yeeb yaj kiab uas muaj kev nyab xeeb thiab polycarbonate, thiab qhov seem yog siv los ua cov txheej txheem txheej txheej, cov hlau tso tseg tus neeg sawv cev, cov pa luam yeeb tshuaj tsuag, polyurethane foaming tus neeg saib xyuas, de-molding pwm Kev puas tsuaj, tus neeg sawv cev lacquer.Dichloromethane yog cov kua tsis muaj xim, uas yog siv los ua cov tshuaj tiv thaiv nruab nrab hauv kev lag luam tshuaj los npaj ammonia penicillin, hydroxycin thiab pioneecin, thiab lwm yam.Organic hluavtaws extracting agents, polyurethane thiab lwm yam yas ua npuas ncauj rau foaming agents thiab hlau tu cov neeg ua hauj.Dichloromethane feem ntau yog siv hauv kev tsim cov yeeb yaj kiab thiab tshuaj hauv Suav teb.Ntawm lawv, kev siv cov yeeb yaj kiab ntau lawm suav txog 50% ntawm tag nrho cov kev siv, cov tshuaj suav rau 20Chemicalbook% ntawm tag nrho cov kev noj, kev noj cov tshuaj ntxuav thiab kev lag luam tshuaj suav txog 20% ntawm tag nrho cov kev noj, thiab lwm yam nyiaj. rau 10%.Dichloromethane kuj tseem siv rau hauv kev lag luam tub yees rau cov tub yees, tab sis nws muaj kev phom sij heev thiab tuaj yeem tsim teeb pom kev zoo thaum hu rau lub teeb hluav taws xob lossis cov khoom kub.Hauv cov huab cua ntub, 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 txias ntawm grain fumigation thiab qis-voltage khov thiab cua-conditioning li.Hauv kev tsim cov polyether-type urinary alkane yas, nws yog siv los ua tus neeg sawv cev ua npuas ncauj, nrog rau cov neeg ua npuas ncauj rau nyem polymutra ua npuas ncauj yas.Dichloromethane kuj tseem siv los ua cov tshuaj rau lub cev qhuav dej kas fes.Lub kas fes ua ntej ua kom yaj cov caffeine thiab ntab rau saum npoo, thiab tom qab ntawd siv dichloromethane tshem tawm caffeine.
1. Nws yog ib qho tsis-combustible low-boiling dot hnyav, uas yog siv los ua acetate cellulose membrane, cua-soluble thiab antibacterial, thiab cov kuab tshuaj nyob rau hauv vitamin ntau lawm.
2. Digerine yog cov khoom siv raw uas tsim los ntawm cov tshuaj tua kab mob azoxazole thiab mimozole, thiab nws kuj yog cov kuab tshuaj zoo.
