Chaw Tsim Khoom Zoo Nqe Methylene Chloride CAS: 75-09-2

piav qhia luv luv:

Methylene Chloride yog ib qho tshuaj uas tsim los ntawm ob lub hydrogen atoms hauv methane molecules, thiab molecular CH2CL2. Methylene Chloride yog tsis muaj xim, pob tshab, hnyav dua, thiab kua dej volatile. Nws muaj ntxhiab thiab qab zib zoo ib yam li ether. Nws tsis hlawv. Methylene Chloride yaj me ntsis hauv dej, thiab nws yaj nrog cov organic solvents feem ntau siv. Nws kuj tseem tuaj yeem yaj hauv txhua qhov sib piv nrog lwm cov chlorine-muaj solvents, ether, ethanol, thiab N-di metamimamamide. Methylene Chloride nyuaj rau yaj hauv cov kua ammonia ntawm chav tsev kub, uas tuaj yeem yaj sai hauv phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. Lub sijhawm Chemicalbook yog 1.3266 (20/4 ° C). Lub ntsiab lus yaj -95.1 ° C. Lub ntsiab lus kub 40 ° C. Cov tshuaj yaj qis -boiling feem ntau siv los hloov cov roj av ether, ether, thiab lwm yam, thiab tuaj yeem siv ua tshuaj loog hauv zos, refrigerant thiab tus neeg sawv cev tua hluav taws. Qhov kub hnyiab yog 640 ° C. Decoction (20 ° C) 0.43MPa · s. Lub refractive index nd (20 ° C) 1.4244. Qhov kub tseem ceeb yog 237 ° C, thiab qhov siab tseem ceeb yog 6.0795MPa. HCL thiab cov teeb pom kev zoo tau tsim tom qab kev daws teeb meem thermal, thiab cov dej tau cua sov rau lub sijhawm ntev los tsim formaldehyde thiab HCL. Ntxiv chloride, CHCL3 thiab CCL4 tuaj yeem tau txais.

Cov ntawv thov ntawm Methylene Chloride

Methylene Chloride (DCM) muaj qhov zoo ntawm kev yaj tau zoo thiab tsis muaj tshuaj lom. Nws yog siv los tsim cov yeeb yaj kiab thiab polycarbonate uas muaj kev nyab xeeb, thiab lwm yam yog siv ua cov tshuaj yaj rau txheej, cov neeg sawv cev tso hlau, cov pa luam yeeb, cov neeg sawv cev ua npuas polyurethane, de-molding pwm puas tsuaj, thiab cov neeg sawv cev lacquer. Dichloromethane yog cov kua tsis muaj xim, uas yog siv ua cov tshuaj tiv thaiv hauv kev lag luam tshuaj los npaj ammonia penicillin, hydroxycin thiab pioneeecin, thiab lwm yam.; Cov neeg sawv cev organic synthetic extracting, polyurethane thiab lwm yam yas ua npuas rau cov neeg sawv cev ua npuas thiab cov neeg sawv cev ntxuav hlau. Dichloromethane feem ntau yog siv hauv kev tsim zaj duab xis thiab tshuaj hauv Suav teb. Ntawm lawv, kev siv cov yeeb yaj kiab suav txog 50% ntawm tag nrho cov kev siv, tshuaj suav txog 20% ntawm tag nrho cov kev siv, kev siv cov neeg sawv cev ntxuav thiab kev lag luam tshuaj suav txog 20% ntawm tag nrho cov kev siv, thiab lwm yam suav txog 10%. Dichloromethane kuj tseem siv rau hauv cov tshuab tub yees rau cov tub yees, tab sis nws muaj kev phom sij heev thiab tuaj yeem tsim lub teeb lom thaum kov cov hluav taws lossis cov khoom kub hnyiab. Yog tias huab cua noo, hydrogen chloride hydrolyzed tuaj yeem siv los txhawb hydrogen chloride, thiab lub teeb kuj tuaj yeem txhawb hydrolysis thiab txhim kho cov hlau corrosive. Siv rau kev txias ntawm cov noob fumigation thiab cov khoom siv khov qis-voltage thiab cua txias. Hauv kev tsim cov yas polyether-hom urinary alkane, nws yog siv ua tus neeg sawv cev pabcuam foaming, nrog rau cov neeg sawv cev foaming rau kev nias polymutra ua npuas ncauj yas. Dichloromethane kuj tseem siv los ua cov tshuaj rau kas fes qhuav. Kas fes ua ntej ua noj kom yaj cov caffeine thiab ntab rau ntawm qhov chaw, thiab tom qab ntawd siv dichloromethane los tshem tawm caffeine.
