Daim ntawv thov
1. Trimethylsilyl cyanide feem ntau yog siv los ua ib qho kev nyab xeeb thiab zoo dua ntawm cyanide anion hauv cov organic synthesis, tshwj xeeb tshaj yog rau kev npaj cov cyanohydrins los ntawm aldehydes thiab ketones ntawm cyanosilylation. Nws kuj yog ib qho tseem ceeb reagent nyob rau hauv cov tshuaj Strecker rau cov synthesis ntawm -aminonitriles thiab amino acids .
2. Trimethylsilyl cyanide CAS 7677-24-9 ua hauj lwm raws li ntau yam silylating thiab cyanating tus neeg sawv cev, ua hauj lwm nyob rau hauv lub synthesis ntawm optically active cyanohydrins, Reissert tebchaw (reactive polyamides), thiab rau converting pyridine-N-oxides rau hauv 2-cyanopyridine. Nws kuj reacts nrog epoxides thiab tertiary alkyl halides los tsim nitriles thiab isocyanides.
3. Cov ntawv thov ntawm Trimethylsilyl cyanide kuj suav nrog nws siv los ua derivatization reagent hauv analytical chemistry (GC-MS-raws li metabolomics), qhov uas nws ua kom pom kev rhiab heev, tsawg dua artifacts, thiab ceev ceev cov tshuaj tiv thaiv rau silylating metabolite mixs piv rau ib txwm reagents.
Cia thiab ceev faj
1. Khaws Trimethylsilyl cyanide nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert gas (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, thiab zoo - qhov chaw ventilated . Pom zoo cia yog tub yees (0-10 degree) vim nws volatility thiab ya raws / tshav kub rhiab heev.
2. Khaws Trimethylsilyl cyanide nruj me ntsis kom deb ntawm dej, noo noo, muaj zog oxidizing tus neeg sawv cev, muaj zog txo tus neeg sawv cev, muaj zog acids, thiab muaj zog hauv paus. Nws yog incompatible nrog cov ntaub ntawv no, reacts nrog dej los tso cov pa phem hydrogen cyanide gas, thiab yog heev flammable (flash point 1 degree).
3. Ib txwm Trimethylsilyl cyanide CAS 7677-24-9 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) suav nrog cov tsom iav kom nruj, tshuaj lom neeg- hnab looj tes tiv thaiv, tiv thaiv lub ntsej muag, thiab nplaim taws- khaub ncaws tiv thaiv kab mob . Kov tsuas yog nyob rau hauv qhov dej- qhov chaw cua los yog cov tshuaj fume hood nrog cov khoom tawg, siv cov cuab yeej uas tsis muaj hluav taws xob, thiab zam kom tsis txhob ua pa pa, huab cua, lossis roj.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw nchuav, tshem tawm cov neeg tsis yog -cov neeg ua haujlwm tseem ceeb, tshem tawm txhua qhov hluav taws kub, thiab xyuas kom muaj cua txaus. Siv cov cuab yeej tiv thaiv tus kheej tag nrho suav nrog tus kheej - muaj cov cuab yeej ua pa (SCBA). Tsis txhob cia Trimethylsilyl cyanide nkag mus rau hauv cov dej ntws los yog txoj kev hauv dej vim nws muaj tshuaj lom heev rau cov dej hauv dej.
2. Muaj Trimethylsilyl cyanide siv qhuav, inert, tsis yog -cov khoom siv hluav taws xob tawg (xws li cov xuab zeb qhuav). Ua tib zoo sau cov khoom tsis huv uas siv cov pa taws- cov cuab yeej pov thawj lossis qhov tawg- pov thawj lub tshuab nqus tsev rau hauv lub kaw lus kaw, sau npe, corrosion- cov khoom pov tseg pov tseg rau cov khoom pov tseg kom raug raws li cov khoom siv phom sij.
3. Cov neeg ua haujlwm Trimethylsilyl cyanide CAS 7677-24-9 yuav tsum hnav PPE haum thaum ntxuav. Ib txoj kev pom zoo pov tseg yog siv cov tshuaj dilute ntawm alkali hydroxide . Trimethylsilyl cyanide yog cais rau kev thauj mus los (UN3383, Hazard Class 6.1/3, Packing Group I) thiab txwv tsis pub thauj huab cua.
Cov ntaub ntawv kev nyab xeeb
1. Trimethylsilyl cyanide yog cais nrog GHS teeb liab lo lus "Danger". Nws yog cov kua ua kua thiab vapor heev (H225), thiab ua rau tuag taus yog tias nqos tau (H300), tiv tauj nrog daim tawv nqaij (H310), thiab yog nqus tau (H330). Trimethylsilyl cyanide CAS 7677-24-9 ua rau tawv nqaij khaus (H315) thiab khaus qhov muag loj (H319).
2. Trimethylsilyl cyanide yog noo noo rhiab heev thiab reacts nrog dej kom tso cov pa phem hydrogen cyanide (HCN) roj (EUH029). Nws yog tshuaj lom heev rau lub neej hauv dej nrog cov teebmeem ntev (H410). Trimethylsilyl cyanide CAS 7677-24-9 muaj qhov taw tes ntawm 1℃(33℃F), qhov kub ntawm 114-119 degree, thiab melting point ntawm 8-12 degree.
3. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Trimethylsilyl cyanide kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem pab (P301+P310+P330 rau kev noj, P303+P361+P353 rau daim tawv nqaij, P304+P340+Pation, P305+P351+P338 rau qhov muag), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P233 (kom kaw lub thawv kaw kom nruj), P260 (tsis txhob ua pa tawm), P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv), P284 (hnav tiv thaiv ua pa), thiab P403+P235 (2} khaws cia hauv qhov chaw txias.
