Daim ntawv thov
1. 2,4-Dimethylpyrrole feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm kev sib txuas ntawm porphyrins, corroles, thiab lwm yam macrocyclic compounds tseem ceeb hauv cov ntaub ntawv tshawb fawb thiab catalysis.
2. 2 4-Dimethylpyrrole CAS 625-82-1 yog lub tsev thaiv ntau yam rau cov tshuaj, agrochemicals, thiab organic dyes lossis pigments.
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb los tsim cov fluorescent probes, sensors, thiab coordination chemistry ligands.
Cia thiab ceev faj
1. Khaws 2,4-dimethylpyrrole nyob rau hauv ib qho chaw inert (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, tsaus qhov chaw, deb ntawm tshav kub, sparks, thiab oxidizing agents.
2. Khaws lub thawv ntim kom nruj thiab tiv thaiv huab cua thiab noo noo los tiv thaiv oxidation thiab polymerization.
3. Kov 2 4-Dimethylpyrrole CAS 625-82-1 nrog cov khoom siv tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab lub tsho (lab), tshwj xeeb hauv lub fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd khiav tawm thiab cais thaj chaw, xyuas kom muaj cua, thiab hnav cov iav tiv thaiv tag nrho (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa).
2. nqus cov kua nrog ib qho inert, 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, cua- nruj rau kev pov tseg pov tseg.
3. Tiv thaiv 2 4-Dimethylpyrrole CAS 625-82-1 lub tebchaw los ntawm kev nkag mus rau hauv cov dej los yog ib puag ncig. Ntxuav thaj chaw nrog cov kuab tshuaj tsim nyog, kom ntseeg tau tias tag nrho cov khoom seem raug sau thiab muab pov tseg kom raug.
Cov ntaub ntawv kev nyab xeeb
1. 2,4-Dimethylpyrrole muaj tshuaj lom heev yog tias nqos, nqus tau, lossis nqus los ntawm daim tawv nqaij. Nws tuaj yeem ua rau lub cev puas tsuaj thiab xav tias yuav ua rau muaj kev cuam tshuam ntawm caj ces.
2. 2 4-Dimethylpyrrole CAS 625-82-1 yog nplaim taws heev thiab rhiab heev rau huab cua thiab lub teeb. Nws cov vapors tuaj yeem tsim tawg sib xyaw nrog huab cua, thiab nws tuaj yeem ua polymerize exothermically thaum raug huab cua lossis oxidizers.
3. Nco ntsoov sab laj nrog daim ntawv pov thawj 2,4-dimethylpyrrole Safety Data Sheet (SDS) thiab tswj nws raws li qhov muaj kev phom sij rau kev noj qab haus huv thiab hluav taws kub nyhiab raws li kev tswj hwm nruj.
