Wopanga Mtengo Wabwino Methylene Chloride CAS:75-09-2

Kufotokozera mwachidule:

Methylene Chloride ndi mankhwala opangidwa ndi maatomu awiri a haidrojeni mu ma molekyulu a methane, ndi molekyulu CH2CL2.Methylene Chloride ndi madzi opanda mtundu, owonekera, olemera, ndi osasinthasintha.Ili ndi fungo ndi kukoma kofanana ndi ether.Sichiwotcha.Methylene Chloride amasungunuka pang'ono m'madzi, ndipo amasungunuka ndi zosungunulira zomwe zimagwiritsidwa ntchito kwambiri.Itha kusungunukanso mwanjira iliyonse ndi zosungunulira zokhala ndi chlorine, etha, ethanol, ndi N-di metamimamamide.Methylene Chloride ndizovuta kusungunula mu ammonia yamadzimadzi kutentha, komwe kumatha kusungunuka mwachangu mu phenol, aldehyde, ketone, methamphetamine, triathrin, tororine, cycamine, acetylcetate.Gawo Chemicalbook ndi 1.3266 (20/4 ° C).The kusungunuka mfundo -95.1 ° C. otentha mfundo 40 ° C. Kwathunthu otsika - otentha mfundo zosungunulira zambiri ntchito m`malo kuyaka mafuta efa, etere, etc., ndipo angagwiritsidwe ntchito ngati m`deralo mankhwala oletsa ululu, refrigerant ndi moto wozimitsa wothandizila.Malo oyatsira modzidzimutsa ndi 640 ° C. Decoction (20 ° C) 0.43MPa · s.Refractive index nd (20 ° C) 1.4244.Kutentha kwakukulu ndi 237 ° C, ndipo kupanikizika kwakukulu ndi 6.0795MPa.HCL ndi mawonekedwe a kuwala amapangidwa pambuyo pa njira yotentha, ndipo madzi amatenthedwa kwa nthawi yaitali kuti apange formaldehyde ndi HCL.Kloridi wowonjezera, CHCL3 ndi CCL4 atha kupezeka.

Kugwiritsa Ntchito Methylene Chloride

Methylene Chloride (DCM) ali ndi ubwino wa kusungunuka kwamphamvu komanso kawopsedwe kakang'ono.Amagwiritsidwa ntchito popanga mafilimu otetezeka ndi polycarbonate, ndipo zotsalazo zimagwiritsidwa ntchito ngati zosungunulira zosungunulira, zitsulo zosiya zitsulo, kutsitsi utsi wa gasi, polyurethane foaming agent, de -molding mold Kuwonongeka, lacquer agent.Dichloromethane ndi madzi opanda colorless, amene ntchito monga anachita sing'anga mu makampani mankhwala kukonzekera ammonia penicillin, hydroxycin ndi pioneecin, etc.;Organic synthetic extracting agents, polyurethane ndi zinthu zina zapulasitiki zopangidwa ndi thovu zopangira thovu ndi oyeretsa zitsulo.Dichloromethane imagwiritsidwa ntchito kwambiri popanga mafilimu ndi mankhwala ku China.Pakati pawo, kugwiritsa ntchito kupanga mafilimu kumapanga 50% ya zinthu zonse zomwe zimagwiritsidwa ntchito, mankhwala amawerengera 20Chemicalbook% yazomwe zimagwiritsidwa ntchito, kugwiritsa ntchito zoyeretsera komanso makampani opanga mankhwala kumapanga 20% yazomwe zimagwiritsidwa ntchito, ndi zina zambiri. kwa 10%.Dichloromethane imagwiritsidwanso ntchito m'mafakitale opangira firiji mufiriji, koma ndi yovulaza kwambiri ndipo imatha kutulutsa kuwala kowopsa mukakumana ndi moto woyaka kapena zinthu zoyaka.Pankhani ya mpweya wonyowa, hydrolyzed hydrogen chloride ingagwiritsidwe ntchito kulimbikitsa hydrogen chloride, ndipo kuwala kungathandizenso hydrolysis ndi kukulitsa zitsulo zowononga.Ntchito kuzirala wa tirigu fumigation ndi otsika-voltage mazira ndi mpweya -conditioning zipangizo.Popanga polyether -mtundu wa mkodzo alkane pulasitiki, amagwiritsidwa ntchito ngati wothandizira thovu, komanso wothandizila thovu pofinya polymutra thovu mapulasitiki.Dichloromethane amagwiritsidwanso ntchito popanga zinthu za khofi wopanda madzi.Khofi amaphika poyamba kuti asungunuke kafeini ndikuyandama pamwamba, kenako gwiritsani ntchito dichloromethane kuchotsa caffeine.
1. Ndi non-combustible otsika-kuwira dontho zosungunulira, amene ntchito ngati acetate mapadi nembanemba, mpweya - sungunuka ndi antibacterial, ndi zosungunulira mu kupanga vitamini.
2. Digerine ndi yaiwisi yopangidwa ndi sterilizers azoxazole ndi mimozole, komanso ndi zosungunulira zabwino.
3. Kuphatikiza pa organic synthetic synthesis, mankhwalawa amagwiritsidwanso ntchito kwambiri ngati acetate cellulose membrane, triax cellulose pump, petroleum dehydration, gasi zolimba ndi maantibayotiki, mavitamini, 甾 mitundu yamitundu, ndi zitsulo pamwamba, ndi zitsulo pamwamba Makalasi Onani CHEMICALBOOK kuti elux ndi decapyles.Komanso, amagwiritsidwa ntchito ozizira ndi otsika -voltage mazira ndi mpweya -conditioning zipangizo.Popanga polyether - mtundu mkodzo alkane pulasitiki, ntchito ngati wothandizira thovu wothandizila, komanso wothandizila thovu pofinya polychida thovu mapulasitiki.
4. Kutulutsa zosungunulira.Ngati imagwiritsidwa ntchito pochotsa caffeine mu nyemba za khofi.Amagwiritsidwanso ntchito ngati zosungunulira kwa mapiri, onunkhira mafuta utomoni, etc. Pigyl kuchepetsedwa wothandizila.
5. Pa zosungunulira, amagwiritsidwanso ntchito popanga organic synthesis.
6. Zosungunulira za utomoni ndi mafakitale apulasitiki.Amagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, mapulasitiki ndi mafilimu.
7. Ethyl cellulose zosungunulira.Wothandizira kuchotsa mafuta ndi mafuta.M'malo mwa ether ndi petroleum ether.
