Daim ntawv thov
1. Ethyl 3-bromopropionate feem ntau yog siv los ua tus neeg sawv cev alkylating thiab ntau lub tsev thaiv hauv cov organic synthesis, tshwj xeeb tshaj yog rau kev qhia txog 3-bromopropionate moiety.
2. Ethyl 3-bromopropionate CAS 539-74-2 ua haujlwm tseem ceeb hauv kev tsim tshuaj, agrochemicals, fragrances, thiab lwm yam tshuaj zoo.
3. Cov tshuaj no kuj tseem siv rau hauv cov tshuaj polymer uas yog monomer lossis cross -linking agent thiab hauv cov ntaub ntawv tshawb fawb.
Cia thiab ceev faj
1. Khaws ethyl 3-bromopropionate nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, tiv thaiv los ntawm lub teeb thiab 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 Ethyl 3-bromopropionate CAS 539-74-2 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, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv tsim nyog ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa).
2. Absorb Ethyl 3-bromopropionate CAS 539-74-2 cov kua uas nchuav nrog cov khoom siv tsis zoo, tsis muaj hluav taws xob (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. Ethyl 3-bromopropionate muaj teeb meem yog tias nqos, nqus tau, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab ua pa ua pa. Nws yog lachrymator (ua rau kua muag).
2. Ethyl 3-bromopropionate CAS 539-74-2 yog flammable thiab nws cov vapors tuaj yeem tsim cov khoom tawg nrog cua.
3. Nco ntsoov sab laj nrog daim ntawv pov thawj ethyl 3-bromopropionate Safety Data Sheet (SDS) kom paub txog kev phom sij, kev tuav pov hwm, thiab cov ntaub ntawv tswj hwm.
