Chloroform Industrial Qib Chloroform Nrog Siab Purity
Cov Khoom Siv
Tsis muaj xim thiab pob tshab kua. Nws muaj kev ua kom muaj zog. Nws muaj ntxhiab tsw tshwj xeeb. Nws qab qab qab zib. Nws tsis hlawv yooj yim. Thaum nthuav tawm lub hnub ci lossis oxidized rau saum huab cua, nws maj mam tawg thiab ua phosgene (carbyl chloride). Yog li ntawd, 1% ethanol feem ntau ntxiv ua stabilizer. It can be miscible with ethanol, ether, benzene, petroleum ether, carbon tetrachloride, carbon disulfide and oil. Iml yog soluble nyob rau hauv txog 200ml dej (25 ℃). Feem ntau yuav tsis hlawv, tab sis ntev ntev tshwm sim qhib cov nplaim taws thiab kub kub tseem tuaj yeem hlawv. Nyob rau hauv dej tshaj, lub teeb, siab kub yuav tshwm sim decomposition, qhov tsim ntawm muaj kuab lom thiab corrosive phosgene thiab hydrogen chloride. Cov hauv paus muaj zog zoo li cov kab thiab cov poov tshuaj hydrocide tuaj yeem tsoo cov chloroform rau hauv chlorates thiab tsim. Hauv kev ua ntawm muaj zog alkali thiab dej, nws tuaj yeem tsim cov khoom tawg. Kev kub siab rau cov dej, corrosive, corrosion ntawm hlau thiab lwm yam hlau, corrosion ntawm plastics thiab roj hmab.
Kev ua
Txoj kev lag luam Trichloromshane tau ntxuav nrog dej kom tshem tawm ethanol, aldehyde thiab ces ntxuav nrog cov sulfuric acid thiab sodium hydroxide tov hauv lem. Cov dej tau sim ua kom alkaline thiab ntxuav ob zaug. Tom qab ziab nrog cov tshuaj pleev roj calhydrous calhium, distillation, kom tau txais cov ntshiab trichloromethane.
Chaw ntim khoom
Chloroform yog cov tshuaj lom neeg organic nquag siv los ua cov kuab tshuaj thiab tshuaj tiv thaiv nruab nrab. Nws yog cov neeg muaj zog heev, cov nplaim taws thiab tawg. Yog li, nco ntsoov cov hauv qab no thaum khaws nws:
1. Kev khaws cia: chloroform yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab muaj kev tiv thaiv zoo los ntawm tshav ntuj thiab kub. Qhov chaw cia yuav tsum nyob deb ntawm hluav taws, kub thiab oxidant, tawg-ntawv pov thawj chaw.
2. Ntim: ChloroForm yuav tsum tau muab cia rau hauv ib lub taub ntim dav hlau ntawm cov khoom ruaj khov, xws li iav iav ruaj khov, cov taub hau yas lossis hlau nruas. Kev ncaj ncees thiab nruj ntawm cov thawv yuav tsum tau kuaj xyuas tsis tu ncua. Chloroform chav yuav tsum cais tawm los ntawm nitric acid thiab alkaline tshuaj los tiv thaiv kev tiv thaiv.
3. Tiv thaiv tsis meej pem: chloroform yuav tsum tsis txhob sib xyaw nrog oxidant muaj zog, muaj zog acid, muaj zog hauv paus thiab lwm yam tshuaj kom tsis txhob muaj kev phom sij. Nyob rau hauv tus txheej txheem ntawm cia, chaw thau khoom, tsis siv thiab siv, saib xyuas yuav tsum tau them los tiv thaiv kev sib tsoo, kev sib txhuam thiab kev sib txhuam, kom tsis txhob muaj tougically.
4. Tiv thaiv cov hluav taws xob zoo li qub: thaum lub sijhawm khaws cia, thauj khoom, thau khoom thiab siv cov tshuaj chloroform, tiv thaiv hluav taws xob zoo li qub. Yuav tsum tau ua kom tsim nyog yuav tsum tau ua, xws li grounding, txheej, cov cuab yeej siv tshuaj tiv thaiv, thiab lwm yam.
5. Daim Ntawv Cim Npe: Lub chlorofoform lub cim yuav tsum khij rau hnub ntshiab, lub npe, kom muaj nuj nqis, kom muaj lwm yam, yog li los pab tswj hwm thiab cim.
Kev siv
Kev txiav txim siab ntawm kev cobalt, manganese, Iridium, iodine, phosphorus extraction tus neeg saib xyuas. Kev txiav txim siab ntawm inorganic phosphorus, organic iav, rog, roj hmab resin, alkaloid, ciab, phosphorus, iodine hnyav hauv ntshav dej.
