Kev piav txog
Tus txheeb ze molecular loj 165.85. Txheeb ze ceev ceev 1.6220. Lub ntsiab lus melting -22.7 ℃. Boiling point 121.2 ℃, 33.2 ℃ (4.000 × 103pa). Cov indexoral index yog 1.5055. Lub viscosity yog 0.839Moos · S (20 ° C). Vapor siab (× 103pa): 5.466 (40 ° C), 13.865 (30.13333, 80 ° C). Tetthylene yog insoluble nyob rau hauv qab zib, glycerin thiab protein thiab protein, thiab yog soluble me ntsis hauv dej (0.015 thaum 25 °, benlorine cov kuab tshuaj. Tsis yog hydrolyzed. Cov tshuaj lom neeg tseem nyob ruaj khov nyob rau 500 ° C hauv qab lub xub ntiag ntawm angless, ya raws thiab tsis muaj catalysts. Tethelhyloethane tuaj yeem tsim tawm thaum hydrogenation. Tiroroethane yog tsim tawm thaum chloride. Tetrachloride kuj tseem tuaj yeem cuam tshuam nrog bromine los tsim cov kab mob bromine hiav txwv chlorine chlorine lossis diptide chloride. Nyob rau hauv qhov kev txiav txim ntawm ib qho catalyst, nws kuj tseem tuaj yeem hnov cov tshuaj fluoride. Nyob rau hauv lub neej ntawm lub teeb, huab cua, thiab dej ntev, nws maj mam decomposide thiab lub teeb corrosive xws li hlau, thiab zinc tuaj yeem raug suppressed nrog stabilizers. Yog tias muaj cov pa roj carbon ua haujlwm, rhuab mus rau 700 ° C kom decompose rau hex chloride thiab hex chloroline. Lub cev nqaijlus tuaj yeem ua tau oxidized los ntawm tus oxidant muaj zog. Tetthyl chloride tuaj yeem muaj cov tshuaj tiv thaiv kev hnyav nrog liab, hmoov dawb, mobthaium dandruff, tetraoxide, thiab sodium hydroxide. Tetrachloride yog tshuaj lom thiab yog ib qho tseem ceeb hauv nruab nrab, uas tuaj yeem ua rau mob taub hau, xeev siab, thiab coma. Tus nas yog LD508850Mg / kg. Qhov siab tshaj plaws tau tso cai rau kev ua haujlwm yog 100 × 10-6.

Cov ntawv thov ntawm perchlorethylene
Hauv kev lag luam, perchlorethylene feem ntau yog siv raws li cov kuab tshuaj, cov khoom siv hluav taws xob, hlau ntxhua khaub ncaws, desulfurizer, tshav kub hloov nruab nrab. Nws yog siv nyiaj ntau li anthelmintic. Nws tseem yog ib nrab ntawm cov khoom siv hauv cov roj ntsha thiab fluorinated fluorinated. Cov neeg nyob hauv cov pej xeem feem ntau yuav raug rau cov dej qis ntawm tetrachlorethylene los ntawm huab cua, zaub mov thiab haus dej. Tetrachlorethylene muaj solubility zoo rau ntau cov inorganic thiab cov roj hmab thiab cov roj hmab sib dhos, cov tshuaj pleev xim rau cov neeg sawv cev, cov roj hmab qhuav , auk hnyav, kua xab npum, cov plaub hauv qib siab thiab cov plaub plaub degree; Tetrachlorethylene tseem siv los ua cov tshuaj pleev ib ce (hookworm thiab qhiav cab); Tus neeg sawv cev ua tiav rau cov khoom lag luam textile.
1. Siv ua Organic kuab tshuaj, qhuav ntxuav tus neeg sawv cev, cov tshuaj ntsuam cov tshuaj ntsuam xyuas thiab cov plaub hau lom zem, thiab lwm yam
2. Tetrachlorethylene yog siv dav siv ua Organic kuab tshuaj, cov huab cua kom qhuav, thiab tseem siv raws li Enteroinsect tshuaj. Tetrachlorethylene tuaj yeem siv tau rog extractant, tua hluav taws tus neeg saib xyuas thiab tshuaj ntsuam xyuas cov tshuaj ntsuam xyuas thiab ua kom cov tshuaj fluorinated.
3. Siv ua Organic kuab tshuaj, qhuav ntxuav tus neeg saib xyuas, desulfurizer thiab Npuag Tiav Tus Neeg Sawv Cev
4. Tetrachlorethylene tau siv dav, tsuas yog siv los ua Organic kuab tshuaj, kuj siv cov kuab tshuaj tua hluav taws, kuj siv cov tshuaj pleev li Chromatographic tsom xam cov khoom. Tetrachlorethylene tuaj yeem siv tau rog extractant, tua hluav taws tus neeg saib xyuas thiab tshuaj ntsuam xyuas cov tshuaj ntsuam xyuas thiab ua kom cov tshuaj fluorinated.
5. Cov taw siv siv los ua cov rog lossis rog zoo li khoom siv hauv cov organic tsom xam. Kev kub siab ua kua chratography reagent. Cov kuab tshuaj rau kev txiav txim siab Spectrophotometric. Organic synthesis.
