Zoo siab Dichloromethane / DCM / Methylene Chloride Organic Solvent CAS 75-09-2

Kev lag luam -Qib DCM Solvent rau Koj Kev Tsim Khoom

Tom ntej: Dichloromethane CAS 75-09-2tseem hu ua methylene chloride yog ib qho organic compound nrog cov tshuaj formula CH₂Cl₂. Nws yog cov kua nplaum uas tsis muaj xim nrog lub qab zib, ether - zoo li tsw. Nws yog me ntsis soluble hauv dej thiab miscible nrog ethanol thiab ether. DCM yog ib qho uas tsis yog - cov kuab tshuaj flammable nrog rau qhov kub siab qis (39.6-40 degree) nyob rau hauv ib txwm muaj. Ntawm qhov kub siab lossis hauv qhov hluav taws kub, nws cov vapor yuav decompose los tsim cov pa phem xws li phosgene thiab hydrogen chloride. DCM cov kuab tshuaj yog dav siv los ua qhov qis dua -flammable lwm txoj rau cov kuab tshuaj xws li roj av ether thiab diethyl ether hauv qee yam kev siv hauv kev lag luam.

Dichloromethane / methylene chloride yog ntau yam muaj kuab tshuaj siv dav siv rau kev rho tawm, ua kom huv, thiab ntxuav cov txheej txheem hauv kev tsim tshuaj thiab tshuaj vim nws muaj zog hnyav thiab tsis tshua muaj nplaim taws.

1. Kev tsim tshuaj

DCM yog ib qho tseem ceeb extraction thiab purification hnyav hauv kev tsim tshuaj, dav siv rau:

• Extracting cov khoom xyaw tshuaj nquag (APIs) los ntawm cov khoom siv ntuj
• Purifying intermediate compounds ntawm recrystallization
• Ua hauj lwm raws li cov tshuaj tiv thaiv nruab nrab rau cov organic synthesis

Keeb kwm siv rau hauv cov txheej txheem decaffeination (tab sis tam sim no feem ntau hloov los ntawm lwm txoj hauv kev siv zaub mov feem ntau vim yog kev cai tswj hwm)

2. Tshuaj Synthesis thiab Cov Tshuaj Tshwj Xeeb

Hauv kev tsim tshuaj lom neeg, methylene chloride ua haujlwm ua cov tshuaj tiv thaiv kev nyab xeeb vim nws cov tshuaj lom neeg ruaj khov thiab muaj peev xwm zoo heev los yaj ntau cov reactants. Common siv muaj xws li:

• Standard organic synthesis cov tshuaj tiv thaiv
• Kev tsim cov polymers, resins, thiab cov tshuaj zoo
• Extraction thiab tshuaj tiv thaiv xov xwm nyob rau hauv tswj systems
• Agrochemical kev tsim khoom

3. Hlau Degreasing thiab Industrial Cleaning

Dichloromethane muaj cov kuab tshuaj muaj zog rau cov roj, roj, thiab cov kab mob organic, ua rau nws muaj txiaj ntsig zoo rau cov txheej txheem vapor degreasing ntawm cov hlau. Kev lag luam vam khom rau daim ntawv thov no suav nrog:

• Aerospace Cheebtsam manufacturing
• Automotive qhov chaw tsim khoom
• Electronics sib dhos
• Precision hlau ua haujlwm

Nws cov volatility sai ua kom cov khoom qhuav sai sai yam tsis muaj qhov seem seem, yog li txo cov kev ua haujlwm rov qab thiab txhim kho kev tsim khoom.

4. Xim thiab txheej tshem tawm

DCM{0}}raws li formulations zoo nkag mus thiab ua txhaum ntau txheej xim, kua roj vanish, thiab coatings. Nws tseem yog qhov kev xaiv zoo tshaj plaws rau cov xim muaj xim - stripping daim ntaub ntawv uas yuav tsum tau ua haujlwm siab thiab ceev.

5. Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Tshawb Fawb Kev Tshawb Fawb

Cov chaw soj ntsuam tshawb fawb cia siab rau DCM rau:

• Ua kua-kua extraction operations
• Kev npaj ntawm chromatographic mobile theem
• Sample pretreatment rau analytical test
• Kev ua haujlwm niaj hnub organic synthesis

•  Tshooj lus ntawm DCM daim ntawv thov: Dichloromethane DCM CAS No . 75-09-2 rau Kev Siv Hluav Taws Xob

Cov tshuaj dichloromethane yuav tsum tau ua tib zoo saib xyuas hauv qhov chaw zoo - qhov cua uas siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab kaw lub kaw lus thaum ua tau, thiab khaws cia rau hauv cov thawv kaw kom nruj hauv qhov chaw txias, qhuav, thiab qhov cua kom deb ntawm tshav kub, oxidizing agents, thiab cov ntaub ntawv tsis sib xws.

1. Pom zoo PPE

• Tshuaj-cov hnab looj tes tiv taus (nitrile, neoprene, lossis butyl roj hmab)
• looj tsom iav dub los yog daim npog ntsej muag
• Cov khaub ncaws tiv thaiv
• Organic vapor respirator nyob rau hauv qhov chaw tsis zoo

2. Engineering tswj

• Siv nyob rau hauv fume hood los yog enclosed systems
• Xyuas kom muaj qhov cua kom zoo
• Siv cov tshuab vapor rov qab rau cov haujlwm loj -

3. Kev cia khoom

• Khaws rau hauv cov thawv kaw nruj nreem
• Khaws cia rau hauv qhov txias, zoo- qhov chaw cua (<40°C)
• Tsis txhob oxidizers, muaj zog hauv paus, thiab reactive hlau
• Siv cov khoom ntim thib ob rau kev tiv thaiv kev nchuav

4. Cov lus teb

• Cov nchuav me me: nqus nrog cov ntaub ntawv inert (vermiculite / xuab zeb)
• Kev nchuav loj: khiav tawm hauv cheeb tsam thiab ua raws li cov txheej txheem xwm txheej ceev
• Tsis txhob tso rau hauv cov kua dej
