Daim ntawv thov
1. Phenylphosphine feem ntau yog siv los ua tus neeg ua ntej thiab txo tus neeg sawv cev hauv kev sib txuas ntawm organophosphorus compounds, suav nrog phosphine ligands, phosphonium ntsev, thiab phosphorus -muaj cov polymers.
2. Phenylphosphine CAS 638-21-1 ua lub ligand hauv kev hloov pauv hlau catalysis thiab ua lub tsev thaiv cov nplaim hluav taws, agrochemicals, thiab tshuaj.
3. Phenylphosphine ua haujlwm ua reagent hauv cov organic synthesis rau kev qhia phosphorus pawg thiab hauv cov khoom siv science rau kev hloov kho saum npoo.
Cia thiab ceev faj
1. Khaws phenylphosphine nyob rau hauv qhov txias, qhuav, zoo- qhov cua qhov chaw, nyob rau hauv ib qho chaw inert (piv txwv li, nitrogen los yog argon), nyob rau hauv nruj nreem kaw, corrosion- tiv taus, thiab siab- ntim ntim los tiv thaiv oxidation, degradation, thiab muaj peev xwm pyrophoric txaus ntshai.
2. Khaws phenylphosphine CAS 638-21-1 nruj nreem cais tawm ntawm huab cua, dej, muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov tshuaj reactive kom tsis txhob muaj kev kub ntxhov exothermic, spontaneous ignition, los yog toxic gas tso (xws li, phosphine).
3. Kov phenylphosphine nrog ceev faj heev uas siv tsis yog- cov cuab yeej hluav taws xob thiab cov khoom siv hauv av; xyuas kom meej tias cov thawv ntim tau sau meej meej tias pyrophoric, flammable, huab cua-sensitive, thiab lom.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab xyuas kom muaj cua txias; zam kev sib cuag nrog dej los yog huab cua thaum lub sij hawm ntim.
2. Rau CAS 638-21-1 me me nchuav nyob rau hauv inert tej yam kev mob, ua tib zoo smother nrog qhuav xuab zeb los yog tshwj xeeb absorbents rau cov ntaub ntawv pyrophoric; sau rau hauv cov thawv kaw, tso cai rau pov tseg raws li cov khib nyiab pov tseg.
3. Hu rau cov kev pabcuam thaum muaj xwm txheej ceev thiab cov kws paub txog cov khoom siv phom sij rau kev ntxuav; Cov chaw uas muaj kab mob yuav tsum tau deactivated nyob rau hauv kev tswj inert tej yam kev mob, thiab tag nrho cov pov tseg pov tseg raws li ib tug heev reactive thiab tshuaj lom cov khoom txaus ntshai.
Cov ntaub ntawv kev nyab xeeb
1. Phenylphosphine yog cov nplaim hluav taws kub heev thiab tuaj yeem ua rau kub nyhiab hauv huab cua (pyrophoric); Nws ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa ua pa thaum sib cuag lossis nqus pa.
2. Phenylphosphine CAS 638-21-1 yog tshuaj lom yog tias nqos, nqus tau, los yog nqus los ntawm daim tawv nqaij, thiab tej zaum yuav ua rau muaj kab mob toxicity (xws li, neurotoxicity) nrog mob los yog rov raug; nws reacts hnyav nrog oxidizers thiab dej.
3. Ib txwm tuav phenylphosphine hauv ib lub hnab looj tes uas tau ntawv pov thawj los yog nyob rau hauv nruj inert tej yam kev mob, hnav PPE tsim nyog nrog rau cov tshuaj - hnab looj tes tiv thaiv, daim npog ntsej muag, tshuaj tsom iav, thiab nplaim taws- khaub ncaws tiv taus; siv cov khoom siv- huab cua tiv thaiv kev ua pa thiab xyuas kom nruj tsis suav nrog huab cua thiab noo noo.
