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

kufotokozera mwachidule:

Methylene Chloride ndi mankhwala opangidwa ndi maatomu awiri a haidrojeni m'mamolekyu a methane, ndi molekyulu ya CH2CL2. Methylene Chloride ndi madzi opanda mtundu, owonekera bwino, olemera, komanso osasunthika. Ali ndi fungo ndi kukoma kofanana ndi ether. Siyaka. Methylene Chloride imasungunuka pang'ono m'madzi, ndipo imasungunuka ndi zosungunulira zachilengedwe zomwe zimagwiritsidwa ntchito kwambiri. Ikhozanso kusungunuka mofanana ndi zosungunulira zina zokhala ndi chlorine, ether, ethanol, ndi N-di metamimamamide. Methylene Chloride ndi yovuta kusungunuka mu ammonia yamadzimadzi kutentha kwa chipinda, yomwe imatha kusungunuka mwachangu mu phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. Gawo la Chemicalbook ndi 1.3266 (20/4 ° C). Malo osungunuka -95.1 ° C. Malo owira 40 ° C. Zosungunulira zomwe zimakhala ndi malo owira otsika kwambiri nthawi zambiri zimagwiritsidwa ntchito m'malo mwa petroleum ether, ether, ndi zina zotero, ndipo zingagwiritsidwe ntchito ngati mankhwala oletsa ululu, firiji ndi chozimitsira moto. Malo oyatsira moto mwadzidzidzi ndi 640 ° C. Decoction (20 ° C) 0.43MPa · s. Chizindikiro cha refractive ndi (20 ° C) 1.4244. Kutentha kofunikira ndi 237 ° C, ndipo kupanikizika kofunikira ndi 6.0795MPa. HCL ndi zotsalira za kuwala zimapangidwa pambuyo pa yankho la kutentha, ndipo madzi amatenthedwa kwa nthawi yayitali kuti apange formaldehyde ndi HCL. Kloridi yowonjezera, CHCL3 ndi CCL4 zitha kupezeka.

Kapangidwe: Dichloromethane yoyera ilibe malo oyaka, ndipo chisakanizo chosungunuka chokhala ndi voliyumu yofanana ya dichloromethane ndi mafuta, naphtha kapena toluene sichingayaka. Komabe, pamene dichloromethane isakanizidwa ndi acetone kapena methanol Chemicalbook liquid pa 10: 1 proportional mixing, chisakanizocho chimakhala ndi malo oyaka, nthunzi ndi mpweya kuti apange chisakanizo chophulika, malire a kuphulika ndi 6.2% ~ 15.0% (voliyumu).

Kugwiritsa Ntchito Methylene Chloride

Methylene Chloride (DCM) ili ndi ubwino wosungunuka kwambiri komanso poizoni wochepa. Imagwiritsidwa ntchito popanga mafilimu otetezeka ndi polycarbonate, ndipo yotsalayo imagwiritsidwa ntchito ngati chosungunulira chophimba, chochotsera zitsulo, chopopera utsi wa gasi, chopopera polyurethane, chowononga nkhungu, chopaka lacquer. Dichloromethane ndi madzi opanda mtundu, omwe amagwiritsidwa ntchito ngati chothandizira mumakampani opanga mankhwala kuti akonze ammonia penicillin, hydroxycin ndi pioneecin, ndi zina zotero; Zopangira zopangira zopangidwa ndi organic, polyurethane ndi zina zopangira pulasitiki ya thovu pazinthu zopangira thovu ndi zotsukira zitsulo. Dichloromethane imagwiritsidwa ntchito kwambiri popanga mafilimu ndi mankhwala ku China. Pakati pawo, kugwiritsa ntchito mafilimu kumawerengera 50% ya ndalama zonse zomwe zimagwiritsidwa ntchito, mankhwala amawerengera 20% ya ndalama zonse zomwe zimagwiritsidwa ntchito, kugwiritsa ntchito chotsukira ndi makampani opanga mankhwala kumawerengera 20% ya ndalama zonse zomwe zimagwiritsidwa ntchito, ndipo zina zimawerengera 10%. Dichloromethane imagwiritsidwanso ntchito m'mafakitale oziziritsira firiji, koma ndi yoopsa kwambiri ndipo imatha kupanga kuwala koopsa ikakhudzana ndi moto wopepuka kapena zinthu zoyaka. Pankhani ya mpweya wonyowa, hydrogen chloride yosungunuka ndi hydrolyzed ingagwiritsidwe ntchito kulimbikitsa hydrogen chloride, ndipo kuwala kungathandizenso hydrolysis ndikuwonjezera chitsulo chowononga. Imagwiritsidwa ntchito poziziritsa fumigation ya tirigu ndi zida zozizira komanso zoziziritsira mpweya zochepa. Pakupanga pulasitiki ya polyether-type urinary alkane, imagwiritsidwa ntchito ngati chothandizira chotulutsa thovu, komanso zotulutsa thovu pofinya pulasitiki ya polymutra foam. Dichloromethane imagwiritsidwanso ntchito popanga zinthu za khofi wouma. Khofi amayamba kuphika kuti asungunuke caffeine ndikuyandama pamwamba, kenako amagwiritsa ntchito dichloromethane kuchotsa caffeine.
1. Ndi chosungunulira chosayaka chomwe chimakhala ndi madontho ochepa owira, chomwe chimagwiritsidwa ntchito ngati nembanemba ya acetate cellulose, chosungunuka ndi mpweya komanso choletsa mabakiteriya, komanso chosungunulira popanga mavitamini.
2. Digerine ndi chinthu chopangidwa ndi azoxazole ndi mimozole, ndipo ndi chosungunulira chabwino.
3. Kuwonjezera pa kupanga zinthu zopangidwa ndi organic, mankhwalawa amagwiritsidwanso ntchito kwambiri ngati acetate cellulose membrane, triax cellulose pump, petroleum dehydration, gas solids ndi antibiotics, mavitamini, 甾 ethnical compounds, ndi zitsulo pamwamba, ndi zitsulo pamwamba Makalasi Check CHEMICALBOOK to elux and decapyles. Kuphatikiza apo, amagwiritsidwanso ntchito pazida zozizira komanso zozizira komanso zoziziritsa mpweya. Pakupanga pulasitiki ya polyether-type urinary alkane, imagwiritsidwa ntchito ngati wothandizira thovu, komanso othandizira thovu pofinya pulasitiki ya polychida foam.
4. Chotsani zosungunulira. Ngati zigwiritsidwa ntchito kuchotsa caffeine mu nyemba za khofi. Zimagwiritsidwanso ntchito ngati zosungunulira za mapiri, utomoni wa mafuta onunkhira, ndi zina zotero. Chosakaniza cha Pigyl diluted.
5. Pa zosungunulira, imagwiritsidwanso ntchito popanga zinthu zachilengedwe.
6. Chosungunulira cha mafakitale a utomoni ndi pulasitiki. Chimagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, pulasitiki ndi mafilimu.
7. Ethyl cellulose solvent. Chothandizira kuchotsa mafuta ndi mafuta. Cholowa m'malo mwa ether ndi petroleum ether.
