Yog tias koj yuav mus rau cov lag luam wholesale bulk dichloroethane ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov mis mos molecular: C₂H₄Cl₂; Molecular Luj: 98.96; Tus qauv qauv: ClCH₂–CH₂Cl
Cov tsos mob: Cov xim tsis muaj xim, pob tshab kua nrog lub qab zib, tsw ntxhiab tsw zoo li chloroform
Melting point: -35.7 ° C
Boiling point: 83.5℃(ntawm atmospheric siab; zoo ib yam li xylene hais ua ntej, tab sis muaj ntau dua polarity)
Qhov ceev: 1.253 g / cm³ (ntawm 20 degree; hnyav dua dej)
Flash point: 13℃(kaw khob)-flammable nrog hnyav vapors; cais raws li Class 3 flammable kua (Packing Group II)
Solubility: me ntsis soluble hauv dej (kwv yees . 8.7 g / L ntawm 20 degree); miscible nrog ethanol, diethyl ether, chloroform, thiab acetone; nthuav tawm lub zog ua kom zoo dua rau ntau cov khoom organic (xws li * p * - chloronitrobenzene, * p * -bromonitrobenzene, thiab methyl cyanoacetate tau hais ua ntej) dua li *n*- hexane lossis * n * -heptane; tsis muaj zog dua DMF tab sis muaj qhov nruab nrab polarity, ua tus sawv cev "nruab nrab polar chlorinated hnyav"
Chemical stability: ruaj khov nyob rau hauv qhuav tej yam kev mob; nyob rau hauv lub xub ntiag ntawm dej ua ke nrog kub kub, acids, los yog hauv paus, nws undergoes dehydrochlorination los ua vinyl chloride (nws yog, qhov tseeb, cov khoom siv raw rau vinyl chloride monomer); Yog li ntawd, cia yuav tsum muaj kev tiv thaiv los ntawm ya raws thiab alkalis.

Vinyl Chloride Monomer (VCM) feedstock: Daim ntawv thov thoob ntiaj teb; Ua los ntawm EDC tawg (EDC → VCM + HCl)
Cov kuab tshuaj: Crystallization hnyav rau cov kws tshuaj / agrochemicals, roj hmab nplaum, xim stripper tivthaiv, thiab tus neeg ua haujlwm rho tawm (dissols fats, waxes, thiab qee yam resins)
Organic synthesis intermediate: Kev tsim cov ethylenediamine (ntawm ammonolysis) thiab chloroacetyl chloride; auxiliary nyob rau hauv malononitrile synthesis routes; nruab nrab rau cyclization cov tshuaj tiv thaiv
Hlau ntxuav / degreasing: Ib qho kev xaiv rau cov laus trichloroethylene-raws li txoj kev (txawm hais tias toxicity tseem siab)

Mob toxicity: Qhov ncauj LD₅₀ hauv nas ≈ 670 mg/kg (mob toxic); inhalation LC₅₀ (4h) kwv yees li . 2000 ppm.
Lub hom phiaj ntawm lub cev: lub siab, lub raum, lub hauv paus paj hlwb; siab -kev nqus tau pa ua rau muaj tshuaj loog thiab plawv arrhythmia.
Carcinogenicity: IARC Pawg 2B (tejzaum carcinogenic rau tib neeg); Feem ntau cuam tshuam nrog hepatic angiosarcoma (txuas mus rau vinyl chloride metabolism, txawm hais tias ntev - raug rau EDC nws tus kheej kuj ua rau muaj kev pheej hmoo).
Kev loj hlob / kev loj hlob: Embryotoxicity pom nyob rau hauv kev tshawb fawb tsiaj; txwv tib neeg pov thawj, tab sis tswj raws li cov khoom muaj teeb meem.
Flammability/Explosion: Explosive limits 6.2%–16% (v/v); vapor yog 3.4 npaug hnyav dua li huab cua, kis raws hauv av, thiab tuaj yeem rov qab mus rau qhov chaw thaum hluav taws kub.
Incompatibilities: Lub hauv paus muaj zog (tsis tswj dehydrochlorination), cov hlau nquag (Al / Zn hmoov ntawm qhov kub thiab txias tuaj yeem tsim cov acetylenic compounds), muaj zog oxidizers.
Kev Tiv Thaiv: Cov kab ke kaw nrog lub qhov cua hauv zos; Qib A tshuaj-cov khoom tiv thaiv (rau qhov raug loj heev), hnab looj tes roj hmab butyl, cov khoom siv hluav taws xob vapor cartridges (muab- cov pa ua pa rau qhov siab); nqus cov dej nchuav nrog xuab zeb lossis lub ntiaj teb - tsis txhob ntws mus rau hauv cov kav dej (s dej hauv qab thiab maj mam tso HCl).
Cia / Thauj: UN 1184, Chav Kawm 3, PG II; khaws qhuav thiab khaws cia cais ntawm cov hauv paus thiab cov khoom noj.
