1-Ethyl-2-acetyl pyrrole (CAS#39741-41-8)

Isingeniso

I-N-ethyl-2-pyrrolidone iwuketshezi olungenambala olunephunga elincane elingajwayelekile. Okulandelayo yisingeniso esinemininingwane yezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-N-ethyl-2-acetylpyrrole:

Ikhwalithi:

- Ukubukeka: I-N-ethyl-2-acetylpyrrole iwuketshezi olungenambala olubonisa ngale.

- Ukunyibilika: I-N-ethyl-2-acetylpyrrole inokuncibilika okuhle emanzini kanye nezinhlobonhlobo zezinyibilikisi eziphilayo.

Sebenzisa:

- I-Solvent: I-N-ethyl-2-acetylpyrrole iyi-solvent enhle kakhulu esetshenziswa kakhulu ezimbonini zamakhemikhali, ezemithi, zezolimo, neze-electronics. Ingasetshenziselwa ukuncibilikisa amakhompiyutha ahlukahlukene ezinto eziphilayo, ama-resin kanye nama-coatings, futhi isetshenziswa ekwakhiweni kwezigqoko, amapende nama-ejenti okuhlanza, njll.

Indlela:

I-N-ethyl-2-acetylpyrrole ivame ukutholwa ngokuphendula i-2-pyrrolidone nge-ethanol. Lokhu kungenziwa ngokusabela ku-2-pyrrolone nge-ethanol usebenzisa i-alkali catalyst ku-250-280 ° C amahora ambalwa.

Ulwazi Lokuphepha:

- Umhwamuko we-N-ethyl-2-acetylpyrrole unomphumela ocasulayo ohlelweni lokuphefumula namehlo, futhi ukuthintana namehlo kungabangela umonakalo. Ukunakekela kufanele kuthathwe ukugwema ukuthintana nesikhumba namehlo lapho usebenzisa noma uphatha.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuphepha, nezihlangu zobuso lapho usebenzisa noma uphatha.

- I-N-ethyl-2-acetylpyrrole kufanele igcinwe endaweni epholile, enomoya omuhle, kude namazinga okushisa aphezulu kanye nomlilo.

- Lapho uphatha inhlanganisela, landela izinqubo zokuphatha ngokuphephile futhi ulahle udoti ngendlela efanele.
