Daim ntawv thov
1. Diethyl azodicarboxylate (DEAD) feem ntau yog siv los ua cov reagent tseem ceeb hauv Mitsunobu cov tshuaj tiv thaiv rau esterification, etherification, thiab amination ntawm cawv.
2. Diethyl azodicarboxylate CAS 1972-28-7 ua hauj lwm ua ib tug ntau yam dehydrogenating tus neeg sawv cev thiab dienophile nyob rau hauv Diels-Alder thiab lwm yam cycloaddition tshuaj.
3. Cov compound no kuj yog siv rau hauv kev sib txuas ntawm heterocycles, kws tshuaj, thiab cov khoom ntuj tsim.
Cia thiab ceev faj
1. Khaws diethyl azodicarboxylate nyob rau hauv lub tub yees (piv txwv li, 2-8 degree) nyob rau hauv ib lub thawv kaw nruj nreem, thawj lub thawv, kom deb ntawm tshav kub, sparks, thiab qhib nplaim taws. ** Khaws cais thiab deb ntawm cov neeg ua haujlwm txo qis, phosphines, lossis lwm yam tshuaj muaj zog heev kom tsis txhob muaj kev kub ntxhov.**
2. Khaws lub thawv rau hauv qhov dej - qhov cua, hluav taws kub- thaj chaw tiv taus, muaj npe kom meej. Diethyl azodicarboxylate CAS 1972-28-7 feem ntau yog muab los ua ib qho kev daws teeb meem (xws li hauv toluene) kom txo tau qhov phom sij.
3. Ua tib zoo ceev faj siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav tiv thaiv, daim npog ntsej muag, thiab lub tsho tiv no. Ib txwm siv lub fume hood thiab xav txog kev tiv thaiv blasting rau ntau qhov ntau.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw. Tsis txhob kov cov khoom uas nchuav. Ceeb toom cov neeg ua haujlwm raug cob qhia. Hnav cov iav tiv thaiv tag nrho ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa).
2. **Tsis txhob siv cov khoom siv hluav taws xob (xws li, ntawv, sawdust) rau kev ntxuav.** Rau cov nchuav me me, ua tib zoo nqus nrog cov khoom tsis zoo, tsis yog- cov khoom siv hluav taws xob (xws li xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv kaw, sau npe rau kev pov tseg pov tseg. Khaws cov khoom ntub nrog cov kuab tshuaj sib xyaw yog tias ua tau.
3. Tiv thaiv Diethyl azodicarboxylate CAS 1972-28-7 los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontaminate cov cuab yeej thiab qhov chaw nrog cov kuab tshuaj haum, ua raws li txhua txoj cai. Kev nchuav loj yuav tsum tau kev pab kws tshaj lij.
Cov ntaub ntawv kev nyab xeeb
1. Diethyl azodicarboxylate yog ** tshuaj lom heev ** yog tias nqos, nqus tau, lossis nqus los ntawm daim tawv nqaij. Diethyl azodicarboxylate CAS 1972-28-7 ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa puas. Nws yog ib tug xav tias carcinogen thiab mutagen.
2. Diethyl azodicarboxylate CAS 1972-28-7 yog ** nplaim taws heev** thiab muaj kev phom sij heev. Nws yog kev poob siab, kub-rhiab heev, thiab tuaj yeem decompose hnyav, tshwj xeeb tshaj yog thaum ntshiab, qhuav, los yog nyob rau hauv kev sib cuag nrog incompatible tshuaj (phosphines, txo cov neeg sawv cev). Nws tuaj yeem tawm cov pa phem (nitrogen oxides, carbon oxides) thaum cua sov.
3. **Nco ntsoov sab laj nrog tus nom diethyl azodicarboxylate Safety Data Sheet (SDS) thiab tuav nws raws li qhov siab - phom sij, flammable, thiab cov khoom muaj tshuaj lom.** Kev cob qhia tshwj xeeb thiab cov txheej txheem yuav tsum tau ua. Tsis txhob siv lossis khaws cia ze rau cov tshuaj tsis sib xws.
