Daim ntawv thov
1. 5-Nitrofurfural feem ntau yog siv los ua ib qho tseem ceeb nruab nrab hauv kev sib txuas ntawm nitrofuran tshuaj tua kab mob thiab lwm yam bioactive molecules.
2. 5-Nitrofurfural CAS 698-}63-5 yog lub tsev thaiv ntau yam rau agrochemicals, dyes, thiab lwm yam nitro-hloov heterocyclic compounds.
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb los tsim cov tshuaj kho tshiab thiab kawm txog nitroheterocyclic chemistry.
Cia thiab ceev faj
1. Khaws 5-nitrofurfural nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, deb ntawm tshav kub, sparks, qhib nplaim taws, thiab combustible khoom. Cov tub yees feem ntau pom zoo.
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, txo cov neeg ua haujlwm, thiab cov hlau.
3. Kov 5-Nitrofurfural CAS 698-63-5 nrog ceev faj heev siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab lub tsho tiv thaiv kev sim. Ib txwm siv lub fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv tag nrho ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa).
2. **Tsis txhob cheb.** Ua tib zoo sau 5-Nitrofurfural nrog ib daim ntaub ntub dej los yog lub tshuab nqus tsev uas muaj HEPA lim. Rau cov kua, siv inert absorbent. Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv kaw, sau npe rau kev pov tseg pov tseg.
3. Tiv thaiv 5-Nitrofurfural CAS 698-63-5 los ntawm kev nkag mus rau hauv cov kav dej, dej phwj tuaj, lossis ib puag ncig. Decontaminate nto nrog dej thiab xab npum, sau cov ntxhua khaub ncaws pov tseg. Cov pa paug paug tuaj yeem ua rau muaj kev phom sij.
Cov ntaub ntawv kev nyab xeeb
1. 5-Nitrofurfural muaj teeb meem yog tias nqos, nqus tau, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij thiab qhov muag khaus, tej zaum yuav mutagenic, thiab tuaj yeem muaj lwm yam toxicity.
2. 5-Nitrofurfural CAS 698-63-5 yog cov khoom siv hluav taws xob thiab tuaj yeem tawg yog tias cua sov hauv qhov chaw kaw. Nitro tebchaw, tshwj xeeb tshaj yog heterocyclic nitro compounds, tuaj yeem ua rau poob siab- thiab kub-rhiab heev. Nws tuaj yeem tawm cov pa phem heev (nitrogen oxides, carbon oxides) thaum cua sov.
3. Nco ntsoov sab laj nrog 5-nitrofurfural Safety Data Sheet (SDS) kom paub txog qhov xwm txheej tam sim no thiab muaj kev nyab xeeb, tuav, thiab cov ntaub ntawv tswj hwm. Tuav nrog ceev faj heev vim nws toxicity thiab muaj peev xwm tawg txaus ntshai.
