Chloroform industrial qib chloroform nrog siab purity
Cov Khoom
Cov kua tsis muaj xim thiab pob tshab. Nws muaj zog refraction. Nws muaj ib tug tshwj xeeb tsw. Nws saj qab zib. Nws tsis yooj yim hlawv. Thaum raug tshav ntuj los yog oxidized nyob rau hauv huab cua, nws maj mam tawg thiab tsim phosgene (carbyl chloride). Yog li ntawd, 1% ethanol feem ntau yog ntxiv ua ib tug stabilizer. Nws yuav sib tov nrog ethanol, ether, benzene, roj av ether, carbon tetrachloride, carbon disulfide thiab roj. ImL yog soluble nyob rau hauv txog 200mL dej (25 ℃). Feem ntau yuav tsis hlawv, tab sis ntev raug rau qhib hluav taws thiab kub siab tseem yuav hlawv. Nyob rau hauv dej ntau dhau, lub teeb, kub siab yuav tshwm sim decomposition, tsim ntawm cov tshuaj lom heev thiab corrosive phosgene thiab hydrogen chloride. Cov hauv paus muaj zog xws li lye thiab potassium hydroxide tuaj yeem rhuav tshem chloroform rau hauv chlorates thiab formates. Nyob rau hauv cov kev ua ntawm muaj zog alkali thiab dej, nws tuaj yeem tsim cov khoom tawg. Kub siab kov dej, corrosive, corrosion ntawm hlau thiab lwm yam hlau, corrosion ntawm yas thiab roj hmab.
Txheej Txheem
Cov tshuaj trichloromethane hauv kev lag luam tau ntxuav nrog dej kom tshem tawm ethanol, aldehyde thiab hydrogen chloride, thiab tom qab ntawd ntxuav nrog cov kua qaub sulfuric acid thiab sodium hydroxide kua ib zaug. Cov dej tau kuaj xyuas kom yog alkaline thiab ntxuav ob zaug. Tom qab ziab nrog anhydrous calcium chloride, distillation, kom tau txais cov trichloromethane ntshiab.
Kev Khaws Cia
Chloroform yog ib hom tshuaj organic uas feem ntau siv ua cov kuab tshuaj thiab cov tshuaj ua rau muaj kev sib kis. Nws yog cov khoom uas yaj sai heev, yooj yim hlawv thiab tawg. Yog li ntawd, nco ntsoov cov hauv qab no thaum khaws cia:
1. Qhov chaw cia khoom: Chloroform yuav tsum khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag tau zoo, kom deb ntawm tshav ntuj ncaj qha thiab qhov kub siab. Qhov chaw cia khoom yuav tsum nyob deb ntawm hluav taws, cua sov thiab oxidant, cov chaw tiv thaiv kev tawg.
2. Kev Ntim Khoom: Cov tshuaj Chloroform yuav tsum tau khaws cia rau hauv lub thawv uas kaw tau zoo, xws li cov fwj iav, cov fwj yas lossis cov thoob hlau. Yuav tsum tau kuaj xyuas tas li seb cov fwj puas ruaj khov thiab ruaj khov. Cov fwj Chloroform yuav tsum tau cais tawm ntawm cov kua qaub nitric thiab cov tshuaj alkaline kom tiv thaiv kev ua xua.
3. Tiv thaiv kev tsis meej pem: chloroform yuav tsum tsis txhob sib xyaw nrog cov tshuaj oxidant muaj zog, cov kua qaub muaj zog, cov hauv paus muaj zog thiab lwm yam tshuaj kom tsis txhob muaj kev phom sij. Thaum khaws cia, thauj khoom, tshem tawm thiab siv, yuav tsum tau ceev faj kom tsis txhob muaj kev sib tsoo, kev sib txhuam thiab kev co, kom tsis txhob muaj kev xau thiab xwm txheej.
4. Tiv thaiv hluav taws xob zoo li qub: Thaum lub sijhawm khaws cia, thauj khoom, tshem tawm thiab siv chloroform, tiv thaiv hluav taws xob zoo li qub. Yuav tsum tau ua cov kev ntsuas tsim nyog, xws li kev sib txuas hauv av, txheej txheej, cov khoom siv tiv thaiv hluav taws xob zoo li qub, thiab lwm yam.
5. Daim ntawv cim qhia: Lub thawv chloroform yuav tsum tau cim nrog cov ntawv cim thiab kev txheeb xyuas meej, qhia hnub cia, lub npe, kev sib xyaw, qhov ntau thiab lwm yam ntaub ntawv, yog li ntawd kom yooj yim rau kev tswj hwm thiab kev txheeb xyuas.
Siv
Kev txiav txim siab ntawm cobalt, manganese, iridium, iodine, phosphorus extraction agent. Kev txiav txim siab ntawm inorganic phosphorus, organic iav, rog, roj hmab resin, alkaloid, wax, phosphorus, iodine solvent hauv serum.
