Chaw Tsim Khoom Zoo Nqe PERCHLOROETHYLENE CAS: 127-18-4

piav qhia luv luv:

PERCHLOROETHYLENE: kuj hu ua tag nrho cov chloride. Hais txog cov qauv molecular, cov tshuaj uas tsim los ntawm tag nrho cov hydrogen atoms hauv ethylene tau hloov los ntawm chlorine. Xyoo 1821, thawj zaug nws tau ua los ntawm FaraDay thermal decomposition. Tsis muaj xim pob tshab kua. Muaj ntxhiab zoo li ether. Tsis kub hnyiab.

Kev piav qhia

Qhov hnyav ntawm cov molecular yog 165.85. Qhov ceev ntawm cov molecular yog 1.6220. Lub melting point yog -22.7 ℃. Boiling point yog 121.2 ℃, 33.2 ℃ (4.000 × 103Pa). Qhov refractive index yog 1.5055. Qhov viscosity yog 0.839MPA · s (20 ° C). Vapor pressure (× 103Pa): 5.466 (40 ° C), 13.865 (60 ° C), 30.131 (80 ° C), 58.128 (100 ° C). Tetthylene tsis yaj hauv qab zib, glycerin thiab protein, thiab yaj me ntsis hauv dej (0.015 thaum 25 ° C), uas tuaj yeem yaj nrog ethanol, ether, chloroform, benzene, thiab chlorine organic solvents. Tsis hydrolyzed. CHEMICALBOOK tseem ruaj khov ntawm 500 ° C nyob rau hauv qhov muaj cua tsis muaj, noo noo thiab tsis muaj catalysts. Tethelhyloethane tuaj yeem tsim tau thaum hydrogenation. Tiroroethane yog tsim thaum lub sijhawm chloride. Tetrachloride kuj tseem tuaj yeem ua rau bromine los tsim bromine dej hiav txwv chlorine lossis diptide chloride. Nyob rau hauv qhov kev ua ntawm catalyst, nws kuj tuaj yeem ua rau hydrogen fluoride. Nyob rau hauv qhov muaj lub teeb, huab cua, thiab dej rau lub sijhawm ntev, nws maj mam decomposed rau hauv trichloride thiab lub teeb, thaum cov hlau corrosive xws li hlau, txhuas, thiab zinc tuaj yeem suppressed nrog stabilizers. Yog tias muaj cov pa roj carbon activated, rhuab mus rau 700 ° C kom decompose rau hex chloride thiab hex chloroline. Tethalothene tuaj yeem oxidized los ntawm ib tug muaj zog oxidant. Tetthyl chloride tuaj yeem muaj cov tshuaj lom neeg hnyav nrog liab, liab hmoov, lithium dandruff, tetraoxide, thiab sodium hydroxide. Tetrachloride yog lom thiab yog ib qho tshuaj inhibitor hauv nruab nrab, uas tuaj yeem ua rau mob taub hau, xeev siab, ntuav, thiab txawm tias coma. Tus nas yog LD508850mg / kg. Qhov siab tshaj plaws uas tso cai rau qhov chaw ua haujlwm yog 100 × 10-6.
