Daim ntawv thov
1. Tributylphosphine yog dav siv raws li ligand nyob rau hauv kev hloov pauv hlau complexes rau homogeneous catalysis, nrog rau olefin polymerization thiab hydroformylation tshuaj. Tributylphosphine CAS 998-40-3 ua haujlwm ua tus neeg sawv cev txo qis rau cleaving disulfide bonds hauv cov protein, tshwj xeeb hauv kev tshawb fawb proteomics rau cov qauv kev npaj ua ntej electrophoresis.
2. Lub compound ua haujlwm ua ntau yam catalyst hauv organic synthesis, suav nrog 1,4-ntxiv cov tshuaj tiv thaiv, acylation, thioetherification ntawm alcohols nrog disulfides, thiab kev npaj ntawm active esters .Tributylphosphine CAS 998-40-3 kuj yog siv nyob rau hauv lub nuclear kev lag luam raws li ib tug hlau extractant rau uranium thiab .
3. Daim ntawv thov ntawm Tributylphosphine txuas mus rau nws siv los ua cov nplaim hluav taws xob ntxiv rau hauv cov yas thiab cov txheej txheem, cov txheej txheem hloov pauv catalyst intermediate, thiab polymerization cross- txuas catalyst .
Cia thiab ceev faj
1. Khaws Tributylphosphine nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib qho chaw inert (argon los yog nitrogen) nyob rau hauv ib tug txias, qhuav, thiab zoo - qhov cua qhov chaw, tiv thaiv los ntawm lub teeb thiab noo noo. Kev khaws cia ntawm chav tsev kub hauv qhov chaw txias, tsaus yog qhov siv tau rau cov khoom siv ntshiab, txawm tias qee qhov kev daws teeb meem xav tau tub yees.
2. Khaws Tributylphosphine nruj me ntsis kom deb ntawm huab cua, noo noo, muaj zog oxidizing cov neeg ua haujlwm, acids, thiab halogens vim nws cov pyrophoric xwm thiab reactivity. Tributylphosphine tuaj yeem ignite spontaneously ntawm kev sib cuag nrog huab cua thiab reacts vigorously nrog oxidizers.
3. Ib txwm Tributylphosphine CAS 998-40-3 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov tshuaj lom neeg- hnab looj tes tiv thaiv (nitrile/neoprene), tsom iav tsom iav, npog ntsej muag, thiab nplaim taws-cov khaub ncaws tiv thaiv zoo li qub. Tuav Tributylphosphine tsuas yog nyob rau hauv lub fume hood nrog inert cua thiab siv cov khoom pov thawj, tawg-pov thawj.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw nchuav (tsawg kawg 50 meters), tshem tawm txhua tus neeg ua haujlwm, thiab tshem tawm tag nrho cov khoom siv hluav taws xob. Tsis txhob siv cov khoom siv hluav taws xob zoo li cov ntaub so ntswg los ntxuav. Tsis txhob sib cuag nrog huab cua thiab dej kiag li.
2. Muaj Tributylphosphine siv qhuav, inert, tsis yog -combustible absorbent khoom (qhuav xuab zeb, vermiculite) nyob rau hauv inert cua yog ua tau. Ua tib zoo sau cov khoom tsis huv uas tsis yog- cov cuab yeej hluav taws xob rau hauv qhov chaw kaw, corrosion- cov khoom siv hluav taws xob tiv thaiv cov khib nyiab purged nrog cov roj inert .
3. Cov neeg ua haujlwm Tributylphosphine CAS 998-40-3 yuav tsum hnav cov khoom siv tshuaj tiv thaiv tag nrho nrog rau qhov zoo ntawm lub tshuab ua pa ntawm tus kheej (SCBA) thaum ntxuav. Tiv thaiv kom tsis txhob nkag mus rau hauv qhov dej los yog txoj kev dej thiab pov tseg tag nrho cov khoom pov tseg raws li cov khoom siv phom sij. Tributylphosphine yog cais rau kev thauj mus los (UN3254, Hazard Class 4.2, PG I).
Cov ntaub ntawv kev nyab xeeb
1. Tributylphosphine yog cais raws li ib tug pyrophoric kua (H250, Danger) uas catches hluav taws spontaneously yog hais tias raug huab cua, thiab yog corrosive ua rau mob hnyav ntawm daim tawv nqaij thiab qhov muag puas (H314/H318). Nws yog flammable nrog flash ntsiab lus qhia los ntawm 58℃mus rau 106℃nyob ntawm tej yam kev mob.
2. Tributylphosphine muaj teeb meem yog tias nqos tau (H302), thaum sib cuag nrog daim tawv nqaij (H312), thiab tej zaum yuav ua rau ua pa (H335). Nws muaj qhov mob qhov ncauj LD50 ntawm kwv yees li 750-820 mg / kg hauv nas. Thermal decomposition ua cov pa phem heev nrog rau phosphine thiab oxides ntawm phosphorus.
3. Tributylphosphine CAS 998-40-3 yog tshuaj lom rau lub neej hauv dej nrog rau cov teebmeem ntev (H411). Nws muaj cov ntxhiab tsw tsw qab thiab yuav tsum tau tuav hauv qhov chaw tsis zoo los tiv thaiv oxidation rau tributylphosphine oxide. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Tributylphosphine kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P302+P334 rau daim tawv nqaij, P305+P351+P338 rau qhov muag, P301+P330+P331 rau kev noj), thiab yuav tsum tau ua .
