Daim ntawv thov
1. 2-Bromobenzyl cyanide feem ntau yog siv los ua ntau yam nruab nrab hauv kev sib txuas ntawm cov tshuaj, agrochemicals, thiab lwm yam tshuaj zoo.
2. 2-Bromobenzyl cyanide CAS 19472-74-3 yog lub tsev tseem ceeb rau kev tsim cov brominated thiab cyanide hloov cov tshuaj tsw qab thiab heterocyclic los ntawm kev ua haujlwm ntxiv (xws li, cyclization, hloov pauv).
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb los tsim cov txheej txheem hluavtaws tshiab thiab ua tus thawj coj rau bioactive molecules.
Cia thiab ceev faj
1. Khaws 2-bromobenzyl cyanide nyob rau hauv qhov chaw txias, qhuav, qhov cua zoo, tiv thaiv lub teeb thiab deb ntawm tshav kub, sparks, thiab qhib nplaim taws.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov khoom muaj zog oxidizing, muaj zog acids, muaj zog hauv paus, thiab txo cov neeg ua haujlwm.
3. Kov 2-Bromobenzyl cyanide CAS 19472-74-3 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus cov pa los yog plua plav, vim nws tuaj yeem tso cov tshuaj lom hydrogen cyanide nyob rau hauv qee yam mob.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw, xyuas kom muaj cua, thiab hnav cov iav tiv thaiv tag nrho (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa tsim nyog rau cov organic vapors / cyanide txaus ntshai).
2. **Tsis txhob siv dej yog tias zam tsis tau.** nqus cov kua uas nchuav nrog ib qho inert, tsis yog{2}} cov khoom siv hluav taws xob (xws li xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, sau tias muaj kev phom sij.
3. Tiv thaiv 2-Bromobenzyl cyanide CAS 19472-74-3 los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontaminate nto nrog cov kuab tshuaj tsim nyog, ua raws li cov cai hauv zos. Paub txog qhov muaj peev xwm tso tawm cyanide, tshwj xeeb tshaj yog nyob rau hauv kev sib cuag nrog cov kua qaub.
Cov ntaub ntawv kev nyab xeeb
1. 2-Bromobenzyl cyanide yog tshuaj lom heev yog tias nqos, nqus tau, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab tej zaum yuav ua rau tuag taus yog tias nqus tau. Nws muaj ob qho tib si bromide thiab cyanide moieties, ua rau muaj kev phom sij txaus ntshai.
2. 2-Bromobenzyl cyanide CAS 19472-74-3 yog combustible thiab tej zaum yuav emit cov pa phem heev (hydrogen cyanide, hydrogen bromide, carbon oxides, nitrogen oxides) thaum tshav kub, hlawv, los yog nyob rau hauv kev sib cuag nrog acids los yog muaj zog oxidizers.
3. Nco ntsoov sab laj nrog tus nom 2-bromobenzyl cyanide Safety Data Sheet (SDS) thiab ua raws li kev noj qab haus huv hnyav thiab phom sij. Yuav tsum tau ceev faj tshwj xeeb rau cov tshuaj cyanide.
