5-Hydroxymethylfurfural CAS:67-47-0

5-Hydroxymethylfurfural (HMF), ine molecular formula C6H6O3, chinhu chakakosha chinobva mufuran chakawanikwa zvakanyanya nekuda kwekushanda kwaro sekemikari yepuratifomu inobva muzviwanikwa zvinogona kudzokororwa. Inonyanya kugadzirwa kuburikidza neacid-catalyzed dehydration yehexose shuga, dzakadai seglucose nefructose, izvo zvinoita kuti ive yakakosha mumamiriro ekushandurwa kwebiomass uye organic chemistry. Chimwe chezvinhu zvakakosha zveHMF kugona kwayo senzira yekutanga yekugadzira makemikari akasiyana-siyana ane mutengo wakakwirira. Izvi zvinosanganisira kugadzirwa kwemafuta ebiofuels, zvinonyungudutsa, uye makemikari akakosha anogona kutsiva mamwe anobva mupetroleum, nokudaro zvichibatsira muindasitiri yemakemikari inogara kwenguva refu. Semuenzaniso, HMF inogona kushandurwa kuita 2,5-dimethylfuran, mukana wekuwana imwe nzira yemafuta anogona kudzokororwa panzvimbo pepeturu. Kuwedzera pakushandiswa kwayo kwemakemikari, HMF inoshandiswawo muindasitiri yechikafu. Inobatsira mukuravira nekunhuhwirira kwezvimwe zvekudya zvakabikwa, kunyanya mukuita kwecaramelize. Zvisinei, kuvapo kwayo muchikafu kwakamutsa kunetseka kwehutano, sezvo HMF inogona kuumbwa panguva yekugadzirisa shuga pakupisa kwakanyanya. Nekuda kweizvozvo, kunzwisisa kuumbwa kwayo uye kuderedza huwandu hwayo muzvigadzirwa zvekudya inzvimbo yekutsvagisa inoenderera mberi. Kukanganiswa kweHMF nharaunda uye kuora kwayo zvinhu zvakakoshawo kufunga nezvazvo. Tsvagiridzo iri kuitwa kuti iongorore kuchengetedzeka kwayo uye mhedzisiro yayo muzvakatipoteredza, kunyanya sezvo kushandiswa kwebiomass sechikafu chekudya kuri kuramba kuchikura. Mukupfupisa, 5-hydroxymethylfurfural inoonekwa nekusiyana kwayo, ichishanda sechivako chakakosha mumakemikari egirini uye inobatsira muhuwandu hwekuravira kwechikafu. Sezvo kufambira mberi mukugadzirwa uye mashandisirwo ari kuramba achienderera mberi, HMF ingangoita basa guru mukuchinja kuenda kuhupfumi hwemakemikari hwakasimba uye hune hushamwari nezvakatipoteredza.
