Daim ntawv thov
1. Diethyl acetylenedicarboxylate feem ntau yog siv los ua ntau yam dienophile thiab Michael lees txais hauv cov organic synthesis, tshwj xeeb hauv Diels-Alder cov tshuaj tiv thaiv los tsim cov complex cyclic thiab heterocyclic compounds.
2. Diethyl acetylenedicarboxylate CAS 762-21-0 ua lub tsev tseem ceeb rau cov tshuaj, agrochemicals, thiab cov ntaub ntawv ua haujlwm nrog pawg ester conjugated.
3. Cov compound no kuj yog siv rau hauv cov synthesis ntawm polymers, ligands, thiab raws li ib tug reagent nyob rau hauv cycloaddition thiab coupling tshua.
Cia thiab ceev faj
1. Khaws cov tshuaj diethyl acetylenedicarboxylate rau hauv qhov chaw txias, qhuav, zoo- qhov cua, tiv thaiv los ntawm lub teeb thiab noo noo, thiab kom deb ntawm tshav kub thiab ignition.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov muaj zog oxidizing cov neeg ua haujlwm, cov hauv paus muaj zog, thiab cov neeg ua haujlwm txo qis.
3. Kov Diethyl acetylenedicarboxylate CAS 762-21-0 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom qhov cua, thiab hnav cov khoom tiv thaiv tsim nyog (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa yog tias vapors tseem ceeb).
2. Absorb Diethyl acetylenedicarboxylate CAS 762-21-0 spill nrog ib qho inert, tsis-combustible khoom (xws li, xuab zeb, vermiculite). Muab cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom pov tseg uas raug kaw.
3. Tiv thaiv qhov sib xyaw kom tsis txhob nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Ntxuav qhov chaw cuam tshuam nrog ib qho tshuaj ntxuav tes thiab dej.
Cov ntaub ntawv kev nyab xeeb
1. Diethyl acetylenedicarboxylate muaj teeb meem yog tias nqos, nqus tau, lossis kov ntawm daim tawv nqaij. Nws ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab ua pa ua pa. Nws yog ib tug muaj zog lachrymator (ua rau tearing).
2. Diethyl acetylenedicarboxylate CAS 762-21-0 yog flammable thiab nws cov vapors tuaj yeem tsim cov khoom tawg nrog cua. Raws li acetylene derivative, nws yuav tsis ruaj khov nyob rau hauv qee yam mob.
3. Nco ntsoov sab laj nrog tus nom diethyl acetylenedicarboxylate Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm. Tuav nrog ceev faj vim nws cov reactivity thiab lachrymatory teebmeem.
