Li-furfural le cob tsa poone li hlahisa ts'ebetso ea boea
Kakaretso
Lisebelisoa tse nang le fiber ea semela sa Pentosan (joaloka Corn cob, likhetla tsa peanut, liqoapi tsa peō ea k'hothone, makhapetla a raese, sawdust, lehong la k'hothone) li tla kenella ka har'a pentose ka mokhoa o phollatsi oa mocheso o itseng le li-catalyst, li-Pentose li siea limolek'hule tse tharo tsa metsi ho etsa
The poone cob sebelisoa ke thepa hangata, 'me ka mor'a letoto la tshebetso tse akarelletsang Tlhoekiso, silakanya, ka acid hydrolysis, setoto distillation, neutralization, dewatering, ho hloekisa fumana furfural tšoanelehang qetellong.

Tlhaho ea lik'hemik'hale
Kaha furfural e na le lihlopha tse sebetsang tsa aldehyde le dienyl ether, furfural e na le thepa ea aldehydes, ethers, dienes le metsoako e meng, haholo-holo e tšoanang le benzaldehyde. Tlas'a maemo a itseng, furfural e ka ba le liphetoho tse latelang tsa lik'hemik'hale:
Furfural e oxidized ho hlahisa maleic acid, maleic anhydride, furoic acid, le furanic acid.
Mokhahlelong oa khase, furfural e oxidized ke ntho e thusang ho hlahisa anhydrous malic acid.
Furfural hydrogenation e ka hlahisa joala bo furfuryl, joala ba tetrahydrofurfuryl, methyl furan, methyl tetrahydrofuran.
Furan e ka etsoa ho tloha mouoane oa metsi le mouoane oa metsi ka mor'a ho tlosoa ha carburization ka mokhoa o nepahetseng.
Furfural e kenella karabelo ea Conicaro tlasa ts'ebetso ea alkali e matla ho hlahisa joala bo furfuryl le sodium furoate.
Furfural e ka kenella karabelong ea Boqin tlasa ts'ebetso ea letsoai le mafura a acid kapa organic base mme e kopanngoa le anhydride ea acid ho theha furan acrylic acid.
Furfural e koaheloa ka metsoako ea phenolic ho hlahisa resin ea thermoplastic; e koaheloa ka urea le melamine ho etsa polasetiki; 'me e koaheloa ka acetone ho etsa resin ea furfurone.
Tšebeliso ea poone
1. E ka sebelisoa ho ntša litšepe tse boima metsing a litšila, ’me e ka sebelisoa ho thibela litšepe tse chesang tse tšesaane hore li se ke tsa khomarelana.
2. E ka sebelisoa ha ho etsoa li-cardboard, boto ea samente le litene tsa samente, 'me e ka sebelisoa e le ho tlatsa sekhomaretsi kapa peista.
3. E ka sebelisoa e le feed premix, methionine, lysine, lysine protheine phofo, betaine, litokisetso tse sa tšoaneng tsa hlobo, li-antifungal agents, livithamine, phospholipids, phytase, li-flavoring agents le madurin, polokeho E tloaelehileng ea enzyme choline chloride, joalo-joalo, li-additives tsa lithethefatsi tsa bongaka ba liphoofolo. , bajari ba phepo e nepahetseng, ba ka nka sebaka sa phofo ea bobeli, hape ke e 'ngoe ea lisebelisoa tse ka sehloohong tsa ho belisoa ha likokoana-hloko. lihlahisoa.
4. E sebelisetsoa ho sebetsana le furfural le xylitol.
