Khaws Diethyl ethylmalonate nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua, tiv thaiv los ntawm lub teeb thiab deb ntawm tshav kub thiab qhib nplaim taws. Pom zoo cia qhov kub thiab txias qis dua 30℃los yog hauv qhov chaw txias, tsaus. Tsis txhob raug huab cua ntev.
2. Khaws Diethyl ethylmalonate kom deb ntawm cov khoom muaj zog oxidizing kom tiv thaiv kev phom sij lossis hluav taws. Nyob ruaj khov nyob rau hauv qhov kub thiab txias.
3. Ib txwm Diethyl ethylmalonate CAS 133-13-1 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav, thiab khaub ncaws tiv thaiv thaum tuav Diethyl ethylmalonate. Siv cov cua kom txaus, tsis txhob tsim cov vapors lossis pos huab, thiab ntxuav kom huv si tom qab tuav.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd muaj cov Diethyl ethylmalonate spill siv inert, tsis yog -cov khoom siv hluav taws xob (xws li, xuab zeb qhuav, universal binder) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej ntws.
2. Ua tib zoo sau Diethyl ethylmalonate CAS 133-13-1 siv cov cuab yeej uas tsis muaj teeb meem lossis lub tshuab nqus tsev tawg rau hauv lub thawv ntim tshuaj khib nyiab pov tseg kom raug raws li cov cai hauv zos, xeev, thiab tseem fwv ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum ntxuav. Xyuas kom muaj qhov cua txaus thiab tshem tawm tag nrho cov khoom siv hluav taws xob. Cov khoom siv tsis raug cais raws li qhov txaus ntshai zoo rau kev thauj los ntawm qee qhov kev cai.
Cov ntaub ntawv kev nyab xeeb
1. Diethyl ethylmalonate yog cais raws li ib tug combustible kua (GHS H227) nrog ib tug flash point ntawm 88 degree. Nws raug cais los ntawm qee qhov chaw ua kua hluav taws xob (H227) nrog cov lus ceeb toom. Nws tuaj yeem ua rau tuag taus yog tias nqos thiab nkag mus rau hauv cov hlab ntsha (H304).
2. Diethyl ethylmalonate tuaj yeem ua rau tawv nqaij khaus (H315), khaus qhov muag loj (H319), thiab ua pa ua pa (H335). Thermal decomposition ua rau cov pa phem thiab khaus khaus xws li carbon monoxide thiab carbon dioxide. Nws muaj kev phom sij rau cov tsiaj hauv dej nrog ntev - cov teebmeem ntev (H412).
3. Ib txwm Diethyl ethylmalonate CAS 133-13-1 sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Diethyl ethylmalonate kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P301+P330+Pestion) cov lus qhia. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P240 (hauv av / daim ntawv cog lus), thiab P280 (coj hnab looj tes tiv thaiv / tiv thaiv qhov muag).
