4. Cov kws tshawb fawb siv 2-Bromopyridine CAS 109-04-6 hauv kev sib xyaw ntawm MAPA (2-methylaminopyridine amide) reagents rau formylation / acylation cov tshuaj tiv thaiv, thiab ua ntau yam synthon rau kev npaj polyheteroarylated 2-pyridones media ntawm Ru(II)

1. 2-Bromopyridine yuav tsum muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua nyob ib puag ncig, tiv thaiv lub teeb vim nws yog lub teeb rhiab heev.
2. Pom zoo cia tej yam kev mob ntawm 0-8℃mus rau chav tsev kub (nyob rau hauv ib tug txias, tsaus qhov chaw hauv qab no 15 degree), nrog rau lub sij hawm ntev cia pom zoo ntawm -20 degree.
3. 2-Bromopyridine CAS 109-04-6 raug cais raws li cov khoom txaus ntshai nrog GHS cov lus qhia "Danger" thiab cov lus hais txog kev phom sij suav nrog H301 (Toxic yog nqos), H310 (Tuag rau ntawm daim tawv nqaij), H226 (Flammable kua thiab vapor), H315 (Ua rau H3013), khaus khaus thiab khaus khaus (Tej zaum ua rau ua pa ua pa).
4. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (cov roj hmab fluorinated rau kev sib cuag tag nrho, cov roj hmab nitrile rau kev sib chwv), nruj nruj tsom iav tsom iav nrog sab- cov ntaub thaiv npog, tiv thaiv lub ntsej muag, thiab cov khaub ncaws tiv thaiv nplaim taws thaum tuav cov tshuaj no.

1. Tshem tawm qhov chaw nchuav tam sim ntawd, xyuas kom muaj qhov cua txaus, tshem tawm txhua qhov chaw ntawm qhov hluav taws kub, thiab hnav cov cuab yeej tiv thaiv tus kheej nrog rau tus kheej -cov cuab yeej ua pa thaum 2-Bromopyridine tso tawm.
2. Sau 2-Bromopyridine CAS 109-04-6 siv cov cuab yeej uas tsis muaj hluav taws xob thiab tawg los ntawm kev nqus nrog cov ntaub ntawv tsis zoo xws li xuab zeb, diatomaceous ntiaj teb, lossis universal binders; rau cov nchuav me me, siv lub tshuab nqus tsev tiv thaiv hluav taws xob los yog txhuam txhuam, thiab muab tso rau hauv cov thawv kaw kom haum rau kev pov tseg.
3. Tsis txhob tsim cov vapors lossis pos huab thaum ntxuav kom tiv thaiv kev ua pa; siv spark- cov khoom pov thawj; dike loj nchuav rau tom qab pov tseg; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej hauv chav dej vim tias nws muaj tshuaj lom rau cov dej hauv dej nrog lub neej ntev -cov teebmeem ntev (WGK Lub Tebchaws Yelemees 3).
4. Tshem tawm cov khoom siv pov tseg raws li cov khoom siv phom sij raws li hauv zos, xeev, thiab tsoomfwv ib puag ncig kev tswj hwm, ceeb toom UN2929 (Flammable kua, tshuaj lom) nrog rau pawg II rau kev thauj mus los.

1. 2-Bromopyridine yog cov kua hluav taws xob uas muaj lub teeb nyem ntawm 54-90.6℃(130-195℃F) thiab NFPA qhov ntsuas hluav taws kub ntawm 2; Nyob rau hauv cov xwm txheej hluav taws kub, cov khoom puas tsuaj muaj xws li cov pa roj carbon monoxide, carbon dioxide, nitrogen oxides (NOx), thiab hydrogen bromide gas.
2. Siv 2-Bromopyridine CAS 109-04-6 qhuav tshuaj hmoov, carbon dioxide, los yog dej cawv-resistant ua npuas ncauj los tua hluav taws uas muaj cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha vim nws tuaj yeem tawg cov khoom siv hluav taws kub thiab kis hluav taws.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub 2-Bromopyridine vim yog cov pa phem uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, txias cov thawv ntim nrog cov tshuaj tsuag dej los ntawm qhov chaw tiv thaiv, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig thiab muaj kuab paug.
