5-Methyl furfural (CAS#620-02-0)

Isingeniso

I-5-Methylfurfural, eyaziwa nangokuthi i-5-methyl-2-oxocyclopenten-1-aldehyde noma i-3-methyl-4-oxoamyl acetate. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-5-methylfurfural:

Ikhwalithi:

Ukubukeka: I-5-Methylfurfural iwuketshezi olungenambala olunephunga elikhethekile.

Ukuminyana: cishe. 0.94 g/mL.

Ukunyibilika: Kungancibilika emanzini, kutshwala nezincibilikisi ze-ether.

Sebenzisa:

I-Chemical synthesis medium: Ingasetshenziswa futhi ekuhlanganiseni ezinye izinhlanganisela eziphilayo nanjengesandulela sokwenziwa se-hydroquinone.

Indlela:

Umzila ojwayelekile wokwenziwa ungokwenza ama-enzyme ahlobene ne-Bacillus isosparatus. Ngokukhethekile, i-5-methylfurfural ingatholwa ngobunzima bokuvutshelwa kwe-butyl acetate.

Ulwazi Lokuphepha:

I-5-Methylfurfural iyacasula isikhumba namehlo, ngakho-ke kufanele unake ukuvikela izandla zakho namehlo futhi ugweme ukuthintana ngesikhathi sokusebenzisa.

Ukuhogela ukugxila okuphezulu kwe-5-methylfurfural kungase kubangele izimpawu ezingakhululekile ezifana nesiyezi nokozela, ngakho qiniseka ukuthi isetshenziswa endaweni enomoya omuhle futhi ugweme ukuchayeka isikhathi eside kumhwamuko omningi.

Lapho ugcina futhi uphatha i-5-methylfurfural, kufanele kuqashelwe ukugwema ukuthintana ne-oxidant ukuvimbela umlilo noma ukuqhuma. Qinisekisa ukuthi isitsha sokugcina sivalwe kahle futhi sigcinwe endaweni epholile, eyomile futhi engenawo umoya, kude nomlilo.
