Daim ntawv thov
1. 3-Nitrobenzyl bromide feem ntau yog siv los ua tus neeg sawv cev alkylating thiab nruab nrab hauv cov organic synthesis rau tshuaj thiab tshuaj agrochemicals.
2. 3-Nitrobenzyl bromide CAS 3958-57-4 ua ntej rau dyes, ligands, thiab lwm yam nitroaromatic compounds.
3. 3-Nitrobenzyl bromide yog ua haujlwm nyob rau hauv cov ntaub ntawv tshawb fawb thiab ua ib qho reagent hauv peptide chemistry.
Cia thiab ceev faj
1. Khaws 3-Nitrobenzyl bromide nyob rau hauv ib lub thawv kaw ntom ntom, lub teeb-tiv taus nyob rau hauv qhov chaw tsis zoo (xws li nitrogen) hauv lub tub yees (2-8 degree), tiv thaiv los ntawm ya raws.
2. Khaws 3-Nitrobenzyl bromide CAS 3958-57-4 kom deb ntawm cov tshuaj oxidizing muaj zog, cov hauv paus muaj zog, txo cov neeg ua haujlwm, thiab cua sov kom tsis txhob muaj kev sib daj sib deev lossis muaj kev phom sij.
3. Kov 3-Nitrobenzyl bromide nrog kev saib xyuas hnyav kom tsis txhob sib cuag ntawm daim tawv nqaij, pom qhov muag, thiab nqus tau cov plua plav lossis vapors; Nws yog tshuaj lom, corrosive, thiab lachrymatory.
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 neeg ua haujlwm tau txais kev cob qhia hauv cov khoom siv tshuaj tiv thaiv tag nrho thiab tus kheej -cov cuab yeej ua pa yuav tsum mus ze.
2. Tsis txhob cheb. Ua tib zoo 3-Nitrobenzyl bromide CAS 3958-57-4 npog qhov nchuav nrog cov xuab zeb qhuav lossis lwm yam inert, tsis-combustible absorbent. Sau rau hauv ib lub thawv ntim, sau npe rau cov khib nyiab halogenated / nitro-compound.
3. Tiv thaiv kom tsis txhob muaj kev sib cuag nrog dej lossis nkag mus rau hauv cov kav dej. Decontaminate cheeb tsam nrog ib tug haum hnyav. Pov tseg cov pov tseg raws li cov tshuaj lom neeg muaj kev phom sij heev raws li kev cai nruj. Cov kws tshaj lij huv tau pom zoo.
Cov ntaub ntawv kev nyab xeeb
1. 3-Nitrobenzyl bromide ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa ua pa. Nws muaj teeb meem yog tias nqos, nqus tau, lossis nqus los ntawm daim tawv nqaij.
2. 3-Nitrobenzyl bromide CAS 3958-57-4 yog ib lub zog lachrymator thiab tej zaum yuav decompose nyob rau hauv tshav kub los yog poob siab, tso pa phem (bromine, nitrogen oxides).
3. Hnav cov cuab yeej tiv thaiv tag nrho (tshuaj lom- hnab looj tes tiv thaiv, tsom iav, daim npog ntsej muag, lub tshuab ua pa) thiab ua haujlwm hauv lub hood fume. Ua tib zoo sab laj nrog Daim Ntawv Qhia Kev Nyab Xeeb ua ntej siv.
