Daim ntawv thov
1. 2-Bromopropionyl bromide feem ntau yog siv los ua tus neeg sawv cev acylating thiab pib hauv atom hloov radical polymerization (ATRP) rau polymer synthesis.
2. 2-Bromopropionyl bromide CAS 563-76-8 ua haujlwm tseem ceeb hauv kev tsim tshuaj, tshuaj agrochemicals, thiab tshuaj zoo.
3. 2-Bromopropionyl bromide yog ua hauj lwm nyob rau hauv qhov chaw functionalization thiab nyob rau hauv lub synthesis ntawm bioactive molecules thiab polymer txhuam.
Cia thiab ceev faj
1. Khaws 2-Bromopropionyl bromide nyob rau hauv lub kaw ntom nti, noo noo- pov thawj, corrosion-resistant thawv nyob rau hauv ib tug inert cua (xws li, nitrogen los yog argon) nyob rau hauv lub tub yees (2-8 degree), tiv thaiv los ntawm lub teeb thiab noo noo.
2. Khaws 2-Bromopropionyl bromide CAS 563-76-8 nruj me ntsis kom deb ntawm dej, cawv, amines, muaj zog hauv paus, thiab oxidizing cov neeg ua haujlwm kom tsis txhob muaj kev kub ntxhov exothermic thiab tso pa tawm.
3. Kov 2-Bromopropionyl bromide nkaus xwb nyob rau hauv lub fume hood uas muaj ntawv pov thawj siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab cov txheej txheem anhydrous; Nws yog corrosive heev, lachrymatory, thiab noo noo-rhiab heev.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw. Xyuas kom muaj cua txias. Tsuas yog cov kws paub tshwj xeeb hauv cov khoom siv tshuaj tiv thaiv tag nrho thiab tus kheej - muaj cov cuab yeej ua pa yuav tsum mus ze.
2. Tsis txhob siv dej. Npog CAS 563-76-8 qhov nchuav nrog cov xuab zeb qhuav los yog lwm yam inert, tsis-combustible absorbent. Sau rau hauv ib lub thawv ntim, sau npe rau cov khib nyiab halogenated heev.
3. Ua tib zoo saib xyuas cov khoom seem nrog cov khoom alkaline (piv txwv li, sodium carbonate) raws li kev tswj hwm. Tiv thaiv kom tsis txhob muaj kev sib cuag nrog dej lossis nkag mus rau hauv cov kav dej. Yuav tsum muaj kev pov tseg pov tseg uas muaj kev phom sij.
Cov ntaub ntawv kev nyab xeeb
1. 2-Bromopropionyl bromide yog tshuaj lom heev, corrosive, thiab ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa ua pa ua rau tuag taus thaum nqus pa.
2. 2-Bromopropionyl bromide CAS 563-76-8 reacts hnyav nrog dej thiab huab cua noo, tso cov pa phem thiab corrosive gases (hydrogen bromide, hydrobromic acid).
3. Cov tshuaj no yog lub zog lachrymator thiab muaj tshuaj lom rau cov dej hauv dej. Cov iav tiv thaiv tag nrho thiab nruj SDS ua raws li yuav tsum tau ua.
