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

Intshayelelo

I-5-Methylfurfural, eyaziwa ngokuba yi-5-methyl-2-oxocyclopenten-1-aldehyde okanye i-3-methyl-4-oxoamyl acetate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-5-methylfurfural:

Umgangatho:

Ukubonakala: I-5-Methylfurfural iyilwelo olungenambala kunye nephunga elikhethekileyo.

Ubuninzi: malunga. 0.94 g/mL.

Ukunyibilika: Inokunyibilika emanzini, utywala kunye nezinyibilikisi ze-ether.

Sebenzisa:

I-Chemical synthesis intermediate: Isenokusetyenziswa kwi-synthesis yezinye iikhompawundi eziphilayo kunye ne-precursor yokwenziwa ye-hydroquinone.

Indlela:

Indlela eqhelekileyo yokwenziwa kukusabela kwe-catalytic ye-Bacillus isosparatus enxulumene ne-enzymes. Ngokukodwa, i-5-methylfurfural inokufunyanwa ngoxinzelelo lwe-fermentation ye-butyl acetate.

Ulwazi ngoKhuseleko:

I-5-Methylfurfural iyacaphukisa ulusu kunye namehlo, ngoko kufuneka ubeke ingqalelo ukukhusela izandla kunye namehlo akho kwaye ugweme ukudibanisa ngexesha lokusetyenziswa.

Ukuphefumla iqondo eliphezulu le-5-methylfurfural kunokubangela iimpawu ezingathandekiyo ezifana nesiyezi kunye nokozela, ngoko ke qinisekisa ukuba isetyenziswa kwindawo enomoya opholileyo kwaye uthintele ukuvezwa ixesha elide kuxinzelelo oluphezulu lomphunga.

Xa ugcina kwaye uphatha i-5-methylfurfural, kufuneka kuthathelwe ingqalelo ukuphepha ukudibana ne-oxidant ukuthintela umlilo okanye ugqabhuko-dubulo. Qinisekisa ukuba isikhongozeli sokugcina sivalwe kakuhle kwaye sigcinwe kwindawo epholileyo, eyomileyo nengena umoya, kude nomlilo.
