Cia thiab ceev faj
1. Khaws dicyclohexylphosphine nyob rau hauv qhov txias, qhuav, zoo- qhov cua qhov chaw, nyob rau hauv ib qho chaw inert (xws li, nitrogen los yog argon), nyob rau hauv nruj nreem kaw, corrosion- resistant ntim los tiv thaiv oxidation thiab degradation.
2. Khaws cov dicyclohexylphosphine CAS 829-84-5 nruj nreem cais los ntawm cov muaj zog oxidizing cov neeg ua hauj, muaj zog acids, thiab reactive tshuaj kom tsis txhob exothermic tshua los yog txaus ntshai decomposition.
3. Kov dicyclohexylphosphine nrog kev saib xyuas hnyav siv tsis yog- cov cuab yeej hluav taws xob thiab cov khoom siv hauv av; xyuas kom cov thawv ntim tau sau meej meej tias yog nplaim taws, huab cua-sensitive, thiab lom.
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 txias; zam kev sib cuag ncaj qha thiab tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog av.
2. Ua tib zoo sau cov spilled dicyclohexylphosphine CAS 829-84-5 siv cov cuab yeej huv, qhuav los yog HEPA-filter nqus tsev vacuum, thiab muab tso rau hauv lub thawv kaw, sau npe rau pov tseg raws li cov pov tseg pov tseg.
3. Ntxuav cov kab mob kom huv si nrog cov kuab tshuaj uas tsim nyog los yog cov tshuaj ntxuav tes hauv kev tswj xyuas; sau tag nrho cov khoom tsis huv thiab muab pov tseg kom ua raws li cov cai hauv zos, hauv teb chaws, thiab thoob ntiaj teb rau phosphorus- muaj cov pov tseg txaus ntshai.
Cov ntaub ntawv kev nyab xeeb
1. Dicyclohexylphosphine muaj teeb meem yog tias nqos, nqus pa, lossis nqus los ntawm daim tawv nqaij, thiab yuav ua rau tawv nqaij khaus, qhov muag loj, thiab ua pa ua pa; nws muaj zog, tsis kaj siab tsw.
2. Dicyclohexylphosphine CAS 829-84-5 yog flammable thiab tej zaum yuav tso tawm cov tshuaj lom phosphorus oxides thaum cua sov los yog combustion; Ntev ntev los yog rov ua dua tuaj yeem cuam tshuam rau qee yam kabmob (piv txwv li, lub paj hlwb).
3. Ib txwm tuav dicyclohexylphosphine hauv lub hood fume hood lossis nrog cov pa hauv zos txaus, hnav PPE tsim nyog nrog rau cov tshuaj lom neeg- hnab looj tes tiv thaiv, daim npog ntsej muag, tshuaj tsom iav, thiab khaub ncaws tiv thaiv.
