Daim ntawv thov
1. Ethyl formate feem ntau yog siv los ua fumigant thiab tshuaj tua kab hauv kev ua liaj ua teb, tshwj xeeb tshaj yog rau kev tswj cov kab hauv cov qoob loo thiab cov txiv hmab txiv ntoo qhuav, ua lwm txoj hauv kev rau methyl bromide. Nws kuj ua raws li tus neeg sawv cev flavoring hauv kev lag luam zaub mov, muab cov txiv hmab txiv ntoo (rum-xws li) tsw rau dej haus, khoom qab zib, thiab cov khoom ci.
2. Ethyl formate CAS 109-94-4 yog dav siv los ua cov kuab tshuaj nyob rau hauv cov organic synthesis rau cellulose nitrate, cellulose acetate, greases, thiab roj, thiab raws li ib tug reagent nyob rau hauv lub formylation ntawm carbanions.
3. Daim ntawv thov ntawm Ethyl formate kuj suav nrog nws siv hauv kev lag luam naj hoom thiab tshuaj tsw qab rau nws cov ntxhiab tsw qab ntxiag, hauv biotechnology rau extraction thiab purification txheej txheem, thiab raws li kev tshawb fawb tshuaj rau kev kawm lipase - catalyzed tshua.
Cia thiab ceev faj
1. Khaws Ethyl formate nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab qhov dej zoo- qhov cua, nyob deb ntawm tshav kub, sparks, thiab qhib nplaim taws; pom zoo cia yog nyob rau hauv chav tsev kub (hauv qab 30 degree) thiab tiv thaiv los ntawm ya raws. Khaws lub thawv hauv av thiab sib txuas kom tsis txhob muaj hluav taws xob hluav taws xob.
2. Khaws Ethyl formate nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, muaj zog hauv paus, thiab nitrates, vim Ethyl formate CAS 109-94-4 tsis sib haum thiab tuaj yeem cuam tshuam nrog cov ntaub ntawv no.
3. Ib txwm siv Ethyl formate CAS 109-94-4 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv (butyl-rubber), tsom iav kev nyab xeeb, thiab khaub ncaws tiv thaiv; tsuas yog siv nrog cov khoom tawg-pov thawj thiab muaj qhov cua txaus hauv lub hood kom tsis txhob ua pa tawm.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav (tsawg kawg 50 meters nyob rau hauv tag nrho cov lus qhia), tshem tawm tag nrho cov ignition qhov chaw, thiab xyuas kom meej qhov cua txaus; muaj Ethyl formate siv inert, tsis yog -cov khoom siv hluav taws xob nqus tau (piv txwv li, xuab zeb qhuav) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws lossis cov dej. Kev pheej hmoo ntawm kev tawg; Tsis txhob ntxuav tawm mus rau hauv cov kav dej.
2. Ua tib zoo sau Ethyl formate CAS 109-94-4 siv lub txim hluav taws xob- cov cuab yeej pov thawj lossis tsis muaj teeb meem (los yog lub tshuab nqus tsev tawg) thiab tso cov kua dej thiab nqus tau rau hauv lub kaw lus kaw, sau tshuaj khib nyiab pov tseg raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg tag nrho - cov khaub ncaws tiv thaiv nrog rau tus kheej -cov cuab yeej ua pa (SCBA) thaum ntxuav. Ethyl formate yog cais rau kev thauj mus los (UN1190, Hazard Class 3, PG II) thiab yuav tsum muaj pov tseg pov tseg pov tseg.
Cov ntaub ntawv kev nyab xeeb
1. Ethyl formate yog cais raws li cov kua ua kua thiab vapor heev (H225, Kev phom sij) nrog lub teeb nyem ntawm -20℃rau -4℃F, thiab nws cov vapors hnyav dua li huab cua, tsim cov khoom tawg nrog huab cua (LEL 2.8%, UEL 16%). Nws muaj teeb meem yog tias nqos tau (H302, LD50 qhov ncauj nas 1850 mg / kg), teeb meem yog tias nqus tau (H332), thiab ua rau mob qhov muag loj (H319) thiab ua pa ua pa (H335).
2. Ethyl formate yog lub hauv nruab nrab lub paj hlwb kev nyuaj siab; Kev nqus pa tuaj yeem ua rau khaus, mob taub hau, kiv taub hau, xeev siab, thiab tsis nco qab ntawm qhov siab. Ethyl formate CAS 109-94-4 decomposes qeeb hauv dej los tsim ethyl cawv thiab formic acid, thiab thermal decomposition ua rau cov pa phem thiab khaus xws li carbon oxides. NIOSH REL thiab OSHA PEL yog TWA 100 ppm (300 mg / m³); IDLH yog 1500 ppm.
3. Nco ntsoov sab laj txog Daim Ntawv Qhia Txog Kev Nyab Xeeb Tshwj Xeeb (SDS) rau Ethyl formate kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem kev pab (P305+P351+P338 rau qhov muag, P303+P361+P353 rau daim tawv nqaij, P301+P330+P331), thiab cov lus qhia txog kev tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P233 (kom kaw lub thawv kom nruj), P240 (hauv av / daim ntawv cog lus), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
