Daim ntawv thov
1. Cyclopropyl bromide feem ntau yog siv los ua ib qho tseem ceeb nruab nrab hauv kev tsim tshuaj thiab agrochemical cov khoom, tshwj xeeb tshaj yog nyob rau hauv cov synthesis ntawm fluoronaphthyridone antibacterial agents thiab fluoroquinolone tshuaj tua kab mob xws li cyclopropane carboxylic acid derivatives.
2. Cyclopropyl bromide CAS 4333-56-6 yog ib lub tsev thaiv ntau yam hauv cov organic synthesis los ua cyclopropyl boric acid thiab koom nrog hauv kev qhib lub nplhaib, nucleophilic hloov pauv, thiab cov hlau-catalyzed transformations vim nws cov qauv broactive reactive .
3. Daim ntawv thov ntawm Cyclopropyl bromide kuj suav nrog nws txoj kev siv hauv kev tsim cov tshuaj nrog kev tiv thaiv -angiogenic cuam tshuam uas cuam tshuam cov hlab ntsha tshiab los ntawm kev cuam tshuam nrog prostaglandin thiab nitric oxide ntau lawm.
Cia thiab ceev faj
1. Khaws Cyclopropyl bromide nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua; pom zoo cia qhov kub thiab txias yog 2-8℃(txias) lossis ntawm -20℃rau kev ruaj ntseg ntev ntawm cov hmoov.
2. Khaws Cyclopropyl bromide nruj nreem kom deb ntawm tshav kub, sparks, qhib nplaim taws, muaj zog oxidizing cov neeg ua hauj, thiab cov hauv paus muaj zog vim nws cov nplaim hluav taws kub thiab incompatibility nrog cov ntaub ntawv no.
3. Ib txwm siv Cyclopropyl bromide CAS 4333-56-6 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav tsom iav, npog ntsej muag, thiab khaub ncaws tiv thaiv; kov tsuas yog nrog cov khoom tawg-pov thawj thiab ua kom muaj cua txaus hauv lub hood fume, thiab siv cov kev ntsuas los tiv thaiv qhov paug tawm.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab xyuas kom muaj cua txaus; muaj Cyclopropyl bromide siv inert, tsis yog - cov khoom siv hluav taws xob nqus tau (piv txwv li, cov xuab zeb qhuav) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws lossis cov dej.
2. Ua tib zoo sau Cyclopropyl bromide CAS 4333-56-6 siv lub tshuab nqus tsev vacuum tiv thaiv hluav taws xob, los ntawm kev txhuam ntub dej, lossis nrog cov cuab yeej tsis ua kom tawg, thiab muab tso rau hauv lub kaw lus kaw, sau cov khib nyiab pov tseg kom raug raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg puv - cov khaub ncaws tiv thaiv nrog rau tus kheej - muaj cov cuab yeej ua pa (SCBA) thaum ntxuav; Cyclopropyl bromide yog cais rau kev thauj mus los (UN1993, Hazard Class 3, PG II) raws li cov kua hluav taws xob hluav taws xob thiab yuav tsum tau pov tseg cov pov tseg pov tseg.
Cov ntaub ntawv kev nyab xeeb
1. Cyclopropyl bromide yog cais raws li ib tug heev flammable kua thiab vapor (H225, Danger) nrog ib tug flash point ntawm -7℃mus rau 20℃F (-6 degree). Nws yog daim tawv nqaij thiab qhov muag muaj zog (H315+H319) thiab tuaj yeem ua rau ua pa (H335).
2. Cyclopropyl bromide muaj qhov kub ntawm 68-70℃thiab qhov ceev ntawm 1.51 g / mL. Nws thermal decomposition los yog combustion ua rau cov pa phem thiab irritating pa xws li carbon oxides thiab hydrogen bromide gas. Cov tshuaj yog lachrymator (tear gas agent).
3. Nco ntsoov sab laj Cyclopropyl bromide CAS 4333-56-6 cov ntaub ntawv tshwj xeeb Kev Nyab Xeeb (SDS) rau Cyclopropyl bromide kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P303+P361+P353 rau daim tawv nqaij, P305+P{{7}, P P301+P330+P331 rau kev noj, P304+P340 rau kev nqus pa), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib nplaim taws), P233 (kom kaw lub thawv kom nruj), P240 (hauv av / daim ntawv cog lus), P261 (tsis txhob ua pa tawm), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
