Daim ntawv thov
1. Diphenylmethoxyphosphine feem ntau yog siv los ua tus neeg sawv cev phosphorylating thiab nruab nrab hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv kev npaj ntawm phosphine oxides, phosphonates, thiab lwm yam organophosphorus tebchaw ntawm Michaelis -Arbuzov cov tshuaj tiv thaiv.
2. Diphenylmethoxyphosphine CAS 4020-99-9 ua lub ligand precursor nyob rau hauv kev hloov cov hlau catalysis thiab raws li ib tug reagent rau qhia cov pab pawg neeg diphenylphosphino rau hauv lub hom phiaj molecules.
3. Diphenylmethoxyphosphine ua haujlwm raws li lub tsev thaiv cov nplaim hluav taws, cov tshuaj agrochemicals, tshuaj, thiab chiral phosphine ligands.
Cia thiab ceev faj
1. Khaws cov tshuaj diphenylmethoxyphosphine 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 hydrolysis thiab oxidation.
2. Khaws diphenylmethoxyphosphine CAS 4020-99-9 nruj me ntsis cais tawm ntawm dej, muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov tshuaj reactive kom tsis txhob muaj kev kub ntxhov exothermic, tso pa tawm (piv txwv li, phosphine), los yog kev puas tsuaj decomposition.
3. Kov diphenylmethoxyphosphine 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 diphenylmethoxyphosphine CAS 4020-99-9 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. Diphenylmethoxyphosphine 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. Diphenylmethoxyphosphine CAS 4020-99-9 yog flammable thiab tej zaum yuav tso 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 diphenylmethoxyphosphine hauv lub hood fume hood lossis nrog cov pa hauv zos txaus, hnav PPE tsim nyog suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv, daim npog ntsej muag, tshuaj tsom iav, thiab khaub ncaws tiv thaiv.
