I-5-Hydroxymethylfurfural CAS:67-47-0

I-5-Hydroxymethylfurfural (HMF), enefomula yama-molecule i-C6H6O3, iyi-furan derivative ebalulekile eye yathola ukunakwa okukhulu ngenxa yokuguquguquka kwayo njengekhemikhali yesikhulumi etholakala ezinsizeni ezivuselelekayo. Ikhiqizwa ngokuyinhloko ngokuphelelwa amanzi emzimbeni koshukela we-hexose okubangelwa yi-acid, njenge-glucose ne-fructose, okwenza kube yinto ebalulekile esimweni sokuguqulwa kwe-biomass kanye ne-chemistry esimeme. Esinye sezimfanelo ezibalulekile ze-HMF amandla ayo njengesandulela sokwenziwa kwamakhemikhali ahlukahlukene anenani eliphezulu. Lokhu kufaka phakathi ukukhiqizwa kwamafutha e-biofuel, izinyibilikisi, namakhemikhali akhethekile angathatha indawo yamakhemikhali atholakala kuphethiloli, ngaleyo ndlela anikele embonini yamakhemikhali esimeme kakhudlwana. Isibonelo, i-HMF ingaguqulwa ibe yi-2,5-dimethylfuran, ukhetho oluthembisayo lwendlela ehlukile kaphethiloli evuselelekayo. Ngaphezu kokusetshenziswa kwayo kwamakhemikhali, i-HMF isetshenziswa futhi embonini yokudla. Inegalelo ekunambithekeni nasephunga lokudla okuthile okuphekiwe, ikakhulukazi ezinqubweni ze-caramelize. Kodwa-ke, ukuba khona kwayo ekudleni kuphakamise ukukhathazeka ngezempilo, njengoba i-HMF ingakhiwa ngesikhathi sokucubungula ushukela emazingeni okushisa aphezulu. Ngenxa yalokho, ukuqonda ukwakheka kwayo nokunciphisa amazinga ayo emikhiqizweni yokudla kuyisici socwaningo oluqhubekayo. Umthelela wemvelo kanye nokubola kwe-HMF nakho kuyizinto ezibalulekile okufanele uzicabangele. Ucwaningo luyenziwa ukuze kuhlolwe iphrofayili yayo yokuphepha kanye nemiphumela yezemvelo, ikakhulukazi njengoba ukusetshenziswa kwe-biomass njengesitokwe sokudla kuqhubeka nokukhula. Ngamafuphi, i-5-hydroxymethylfurfural ivelele ngokusebenza kwayo okuningi, isebenza njengesisekelo esibalulekile kumakhemikhali aluhlaza kanye nomthelela kumaphrofayili okunambitheka kokudla. Njengoba intuthuko ekuhlanganisweni nasekusetshenzisweni iqhubeka, i-HMF cishe izodlala indima ebalulekile ekuguqukeleni emnothweni wamakhemikhali ozinzile futhi onobungane nemvelo.
