Yog lawm, ethyl acetate (CAS 141 78 6) kua yog cov nplaim taws heev. Nrog lub teeb nyem qis li -4℃(24℃F), nws ignites yooj yim heev ntawm chav tsev kub.Nws cov vapors tuaj yeem tsim cov khoom tawg nrog huab cua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaw lossis qhov cua tsis zoo.
Ethyl acetate (ETAC / EtOAc) yog cov organic hnyav siv dav hauv kev lag luam xws li tshuaj, txheej, nplaum, thiab ua zaub mov. Thaum tuav cov kuab tshuaj no, nws cov flammability yog ib qho tseem ceeb ntawm kev saib xyuas kev nyab xeeb.
Cov Khoom Tseem Ceeb Flammability ntawm Ethyl Acetate
| Flash Point | -4 degree |
| Boiling Point | 77.1 degree |
| Auto-ignition Temperature | 426 degree |
| Explosive txwv nyob rau hauv huab cua | 2.2% – 11.5% |
| Vapor Density | Hnyav tshaj huab cua |
Vim li cas Ethyl Acetate (CAS 141-78-6) Cov nplaim hluav taws kub heev?
Ethyl acetate / EtOAcyog cais raws li cov kua nplaum heev, ib qho kev xaiv feem ntau ntaus nqi rau nws qhov tsis tshua muaj flash point thiab tshwj xeeb tshaj yog siab volatility. Nyob rau hauv tus txheej txheem kub thiab siab tej yam kev mob, nws evaporates nrog zoo heev yooj yim; lub resulting vapors tuaj yeem sib xyaw nrog huab cua los ua ib qho sib xyaw flammable.
Nws cov flammability siab yog txiav txim siab los ntawm ntau yam tshuaj thiab lub cev muaj zog:
- Qhov taw tes qis heev (-4 degree)
- Tus nqi evaporation ceev heev
- Siab vapor siab
- Ib qho vapor ntom ntau dua li huab cua
Vim tias nws cov vapors hnyav dua li huab cua, lawv nyiam nyob twj ywm thiab kis mus rau hauv av; yog li ntawd, txawm tias qhov hluav taws xob nyob deb tuaj yeem ua rau lawv. Muab cov yam ntxwv no, tag nrho cov chaw muaj kev lag luam uas ethyl acetate tau ua haujlwm yuav tsum nruj me ntsis ua raws li cov txheej txheem kev nyab xeeb ntawm hluav taws txhua lub sijhawm.
Vim li cas ethyl acetate muaj kev phom sij hauv ib puag ncig kev lag luam?
Ethyl acetate vapors sib sau tau yooj yim heev hauv cov cheeb tsam uas muaj qhov cua tsis zoo lossis qhov cua tsis zoo. Kev ua pa tsis txaus tuaj yeem ua rau cov vapor concentrations kom ncav cuag lawv qhov kev txwv tsis pub muaj hluav taws xob hauv huab cua (xws li 2.2% mus rau 11.5% los ntawm ntim), yog li tsim kom muaj kev pheej hmoo loj ntawm kev tawg. Cov khoom siv hluav taws xob muaj xws li hluav taws xob zoo li qub, hluav taws xob qhib, cov khoom siv kub kub, hluav taws xob hluav taws xob, thiab kev ua haujlwm vuam.
Yog li ntawd, thaum lub sij hawm tag nrho cov tuav, twj, thiab hloov pauv kev ua haujlwm uas muaj ethyl ethanoate, yuav tsum siv tawg- cov khoom pov thawj thiab txhim khu kev qha hauv av zoo li qub yog qhov tseem ceeb los txo cov kev phom sij zoo.
Dab tsi yog qhov kev tiv thaiv kev nyab xeeb rau ethyl acetate?
Kev Tiv Thaiv Kev Tiv Thaiv
- Flammability Control: Ethyl acetate yog cov kua ua kua thiab vapor heev. Kov tsuas yog hauv qhov dej zoo- qhov cua; siv tawg- cov khoom pov thawj hluav taws xob thiab qhov cua.
- Electrostatic Precautions: Hauv av thiab daim ntawv cog lus ntim thaum hloov mus los tshem tawm qhov kev pheej hmoo ntawm hluav taws xob zoo li qub.
- Kev Tiv Thaiv Kev Tiv Thaiv: Tsis txhob nqus cov pa, huab cua, lossis roj. Tiv thaiv qhov muag, tawv nqaij, thiab khaub ncaws.
- Kev tu tus kheej: Tsis txhob noj, haus, lossis haus luam yeeb thaum tuav. Ntxuav tes thiab ntsej muag kom huv si tom qab tuav.
Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
- Kev Tiv Thaiv Qhov Muag: Hnav tsom iav kev nyab xeeb; hnav daim npog ntsej muag yog tias tsim nyog.
- Tiv thaiv daim tawv nqaij: Hnav hnyav- hnab looj tes tiv thaiv (butyl roj hmab pom zoo) thiab cov khaub ncaws tiv thaiv.
- Kev Tiv Thaiv Kev Ua Phem: Yog tias qhov cua tsis txaus, hnav lub tshuab ua pa uas muaj ntau- lub hom phiaj lim cartridge lossis tag nrho - lub ntsej muag ua pa.
Kev Cia Siab
- Khaws cov thawv kaw kom nruj thiab khaws cia rau hauv qhov chaw qhuav, txias, thiab zoo - qhov cua.
- Khaws kom deb ntawm qhov chaw tshav kub, cov nplaim taws, qhib nplaim taws, qhov chaw kub, thiab muaj zog oxidizing cov neeg ua haujlwm.
- Txhua lub thawv ntim tau sau nrog cov ntaub ntawv txaus ntshai.
