Daim ntawv thov
1. Methyl propiolate yog siv nyob rau hauv lub synthesis ntawm polysubstituted 3-arylaminoacrylate thiab tetrahydropyrimidin-2-ib derivatives .
2. Methyl propiolate CAS 922-67-8 yog ib tug thiol derivatizing tus neeg sawv cev rau capillary electrophoresis daim ntaub ntawv.
3. Methyl propiolate koom nrog dawb - radical ntxiv ntawm diselendide thiab conjugate ntxiv cov tshuaj tiv thaiv catalyzed los ntawm fluoride .
Cia thiab ceev faj
1. Khaws Methyl propiolate nyob rau hauv inert gas (argon filling) nyob rau hauv ib tug txias, qhuav qhov chaw ntawm 2-8 degree, tiv thaiv los ntawm lub teeb.
2. Khaws Methyl propiolate CAS 922-67-8 nruj me ntsis kom deb ntawm cov oxidizing muaj zog, acids, thiab cov hauv paus vim tsis sib haum.
3. Kov Methyl propiolate siv cov cuab yeej tiv thaiv tus kheej tsim nyog suav nrog tshuaj lom neeg - hnab looj tes tiv thaiv thiab tsom iav kev nyab xeeb, thiab siv rau hauv qhov dej - qhov cua los yog fume hood .
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab muaj cov kua Methyl propiolate siv cov khoom uas tsis yog-combustible absorbent xws li xuab zeb, tiv thaiv kev nkag mus rau hauv qhov dej los yog hauv dej.
2. Sau absorbed Methyl propiolate CAS 922-67-8 siv cov cuab yeej uas tsis muaj teeb meem rau hauv cov ntim ntim, cov ntawv lo rau pov tseg raws li kev cai ib puag ncig.
3. Cov neeg ua haujlwm tu Methyl propiolate spills yuav tsum hnav cov khoom tiv thaiv tag nrho nrog rau tus kheej - muaj cov cuab yeej ua pa, vim Methyl propiolate yog cov nplaim hluav taws kub heev (UN3272, Hazard Class 3, Packing Group II).
Cov ntaub ntawv kev nyab xeeb
1. Methyl propiolate yog cov nplaim taws heev (flash point 16 degree) thiab raug cais nrog GHS teeb liab lo lus "Danger" thiab cov nqe lus txaus ntshai H225, H315, H319, H335 .
2. Methyl propiolate CAS 922-67-8 ua rau tawv nqaij khaus (H315), khaus qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335).
3. Methyl propiolate muaj qhov kub ntawm 103-105 degree, ntom ntawm 0.945 g / mL, thiab yog insoluble hauv dej.
