Tom ntej: Hexamethyldisilane CAS 1450-14-2

1. Hexamethyldisilane yog dav siv los ua ntau yam silylating reagent nyob rau hauv cov organic synthesis los qhia cov pab pawg trimethylsilyl rau hauv cov molecules xws li cawv, amines, thiab acids, feem ntau muaj chemoselectivity siab. Hexamethyldisilane CAS 1450-14-2 yog ua haujlwm nyob rau hauv synthesis ntawm kws tshuaj (xws li, beta-lactam tshuaj tua kab mob), agrochemicals, dyes, naj hoom, thiab nyob rau hauv kev tiv thaiv ntawm reactive chaw nyob rau hauv carbohydrates thiab nucleosides .
2. Cov khoom sib xyaw ua haujlwm tseem ceeb ua ntej rau silicon-raws li cov yeeb yaj kiab nyias thiab silicon carbide (SiC) tso rau hauv cov khoom siv hluav taws xob semiconductor thiab cov ntaub ntawv tshawb fawb. Hexamethyldisilane CAS 1450-14-2 kuj tseem siv rau hauv kev tsim cov hydrophobic nto coatings, nplaum formulations, thiab nyob rau hauv nanotechnology kev tshawb fawb rau fabricating nanostructured ntaub ntawv.
3. Cov ntawv thov ntawm Hexamethyldisilane suav nrog nws lub luag haujlwm hauv cov tshuaj tiv thaiv tshwj xeeb, xws li tooj liab -catalyzed cyanation ntawm arenes thiab stereospecific deoxygenation cov tshuaj tiv thaiv . Nws kuj ua haujlwm raws li cov kuab tshuaj nyob rau hauv polar / nonpolar cov kuab tshuaj thiab ua ib qho kev sib txuas lossis tso tawm tus neeg sawv cev.

1. Khaws Hexamethyldisilane nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert roj (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, zoo- qhov cua qhov chaw, deb ntawm tshav kub, sparks, thiab qhib nplaim taws. Qhov ntsuas kub tau pom zoo yog chav ntsuas kub (nyob rau hauv qhov chaw txias, qhov chaw tsaus, qhov zoo tshaj plaws hauv qab 15 degree) lossis ntev - lub sijhawm cia nyob rau hauv qhov chaw txias, qhuav. Hexamethyldisilane CAS 1450-14-2 yog noo noo rhiab heev thiab yuav tsum tiv thaiv huab cua, lub teeb, thiab av noo.
2. Khaws Hexamethyldisilane nruj me ntsis kom deb ntawm cov khoom muaj zog oxidizing, muaj zog acids, thiab cov hauv paus muaj zog vim nws tsis sib haum thiab muaj kev pheej hmoo ntawm kev phom sij los yog decomposition. Hauv av thiab daim ntawv cog lus ntim thiab txais cov khoom siv los tiv thaiv kev tawm static.
3. Ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov tshuaj lom neeg - cov hnab looj tes tiv thaiv, hnav tsom iav kom nruj, tiv thaiv ntsej muag, thiab hnav khaub ncaws tiv thaiv. Siv cov khoom tawg yooj yim nkaus xwb- cov khoom pov thawj thiab qhov cua txaus (xws li, tshuaj fume hood) kom tsis txhob ua pa pa, pos huab, lossis roj.

1. Tam sim ntawd cais qhov chaw nchuav (tsawg kawg 50 meters nyob rau hauv tag nrho cov lus qhia), tshem tawm tag nrho cov ignition qhov chaw (tsis txhob haus luam yeeb, nplaim taws, los yog sparks), thiab muab qhov cua txaus. Muaj Hexamethyldisilane siv qhuav, inert, tsis yog - cov khoom siv hluav taws xob uas nqus tau (xws li cov xuab zeb qhuav) thiab tsis txhob sib cuag nrog dej kiag li. Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis cov kav dej.
2. Ua tib zoo sau Hexamethyldisilane CAS 1450-14-2 siv tsis yog- cov cuab yeej hluav taws xob (los yog lub tshuab nqus tsev tawg) rau hauv lub thawv ntim khoom, cov ntawv sau, cov tshuaj tiv thaiv corrosion-resistant rau pov tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig. Rau kev nchuav loj, dike rau tom qab pov tseg thiab npog nrog ua npuas ncauj kom txo cov vapors.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg tag nrho- cov khoom siv tiv thaiv nrog rau qhov zoo siab rau tus kheej- muaj cov cuab yeej ua pa (SCBA) thiab tshuaj lom neeg- khaub ncaws tiv taus thaum ntxuav. Hexamethyldisilane yog cais rau kev thauj (UN1993, Hazard Class 3, Packing Group II).

1. Hexamethyldisilane yog cais raws li cov kua thiab vapors heev (H225, Danger) nrog lub teeb nyem ntawm -9℃mus rau -1.67 degree. Nws ua rau qhov muag khaus loj (H319), yuav ua rau muaj kev tsis haum rau ntawm daim tawv nqaij (H317), thiab yuav ua rau ua pa (H335). Vapor / cua sib tov yog tawg.
2. Hexamethyldisilane has very low acute oral toxicity (rat LD50 >20 g / kg). Nws yog noo noo rhiab heev thiab decomposes ntawm kev sib cuag nrog huab cua, lub teeb, los yog cua sov, tso pa lom thiab irritating fumes nrog rau oxides ntawm carbon thiab silicon. Tej zaum nws yuav ua rau ntev - muaj kev phom sij rau lub neej hauv dej (H413).
3. Nco ntsoov sab laj nrog Hexamethyldisilane CAS 1450-14-2 daim Ntawv Qhia Txog Kev Nyab Xeeb Tshwj Xeeb (SDS) rau Hexamethyldisilane kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P303+P{7}}P3{0}), P353 rau daim tawv nqaij, tuav cov txheej txheem. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P233 (kom kaw lub thawv kom nruj), P240 (hauv av / daim ntawv cog lus), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
