Daim ntawv thov
1. Cinnamyl bromide yog ib lub tsev thaiv ntau yam nyob rau hauv cov organic synthesis, tshwj xeeb yog siv los regioselectively npaj 3-O- hloov pauv beta-cyclodextrin derivatives rau supramolecular chemistry .
2. Cinnamyl bromide CAS 4392-24-9 yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj chemistry rau synthesizing N-cinnamyl-substituted isatin derivatives soj ntsuam rau lawv cov tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv kab mob.
3. Cinnamyl bromide ua haujlwm raws li precatalyst nyob rau hauv photocatalytic systems los tsim bromine radicals, ua kom muaj kev cuam tshuam cycloaddition nyob rau hauv cov mob me.
Cia thiab ceev faj
1. Khaws Cinnamyl bromide nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert roj ntawm cov tub yees txias (2-8 degree), vim Cinnamyl bromide yog lub teeb rhiab heev thiab kub rhiab heev.
2. Khaws Cinnamyl bromide CAS 4392-24-9 nruj me ntsis kom deb ntawm cov neeg muaj zog oxidizing thiab nyob rau hauv lub thawv corrosive-resistant, raws li Cinnamyl bromide yog cais rau kev thauj khoom raws li cov khoom corrosive (UN 3261, Hazard Class 8, Packing Group II/III).
3. Kov Cinnamyl bromide siv cov cuab yeej tiv thaiv tus kheej tsim nyog suav nrog tshuaj lom neeg - cov hnab looj tes tiv thaiv thiab cov tsom iav nruj nruj, vim tias Cinnamyl bromide ua rau tawv nqaij kub hnyiab thiab qhov muag loj.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, zam cov plua plav tsim, thiab hnav cov cuab yeej tiv thaiv tag nrho nrog rau tus kheej -cov cuab yeej ua pa ua ntej tuav Cinnamyl bromide .
2. Sweep li spilled Cinnamyl bromide CAS 4392-24-9 siv cov khoom pov thawj pov thawj rau hauv cov thawv ntim, cov ntawv ntim corrosive-resistant rau pov tseg raws li ib puag ncig cov cai.
3. Tiv thaiv kom tsis txhob nchuav Cinnamyl bromide los ntawm kev nkag mus rau hauv cov dej ntws los yog txoj kev hauv dej, nqus cov spillage los tiv thaiv cov khoom puas tsuaj, thiab pov tseg cov pov tseg los ntawm kev tswj incineration nrog flue gas txhuam.
Cov ntaub ntawv kev nyab xeeb
1. Cinnamyl bromide yog cais nrog GHS teeb liab lo lus "Danger" raws li cov khoom siv corrosive (H314, H318) ua rau tawv nqaij kub hnyiab, mob qhov muag loj, thiab tej zaum yuav corrosive rau hlau (H290).
2. Cinnamyl bromide CAS 4392-24-9 muaj NFPA kev ntsuam xyuas kev noj qab haus huv ntawm 3 (muaj kev phom sij hnyav), flash point qhov tseem ceeb xws li 16℃mus rau 87℃nyob ntawm txoj kev ntsuas, thiab muaj teeb meem yog tias nqos tau.
3. Cinnamyl bromide muaj qhov melting point ntawm 26-29 degree, boiling point ntawm 103-107 degree, ceev ntawm 1.332 g / mL, yog insoluble nyob rau hauv dej, thiab yog lub teeb rhiab heev nrog rau lub sij hawm ntev stability yuav tsum tau khaws cia kaw.
