Furfural ma aka sana e maua ai le furfural process
Aotelega
O mea o lo'o i ai alava laau Pentosan (e pei o le saito, atigi pinati, fuga fatu, hulls araisa, sawdust, cotton wood) o le a hydrolysis i le pentose i le fluence o le vevela patino ma le faʻamalosi, Pentoses tuʻu ese tolu mole vai e fausia furfural.
O le cob sana o loʻo faʻaaogaina e mea masani, ma a maeʻa se faasologa o gaioiga e aofia ai le Faʻamamāina, tuʻimomomoina, ma le acid hydrolysis, mash distillation, neutralization, dewatering, faamamaina maua le furfural agavaa i le faaiuga.
O le "Ta'oto'o" o le a tu'uina atu i le afi fa'avela, o le pefu e mafai ona fa'aaogaina e fai ma mea fa'atumu mo le atina'e po'o le organic.
Lona tolu, o le siata o le faagasologa:
natura fa'ama'i
Talu ai ona o le furfural ei ai le aldehyde ma le dienyl ether vaega galue, o le furfural ei ai meatotino o aldehydes, ethers, dienes ma isi tuufaatasiga, aemaise lava e tutusa ma le benzaldehyde. I lalo o nisi tulaga, furfural e mafai ona oʻo i gaioiga faʻainisinia nei:
Furfural ua oxidized e maua maleic acid, maleic anhydride, furoic acid, ma furanic acid.
I le vaega o le kesi, o le furfural e fa'ama'iina e se fa'amalosi e fa'atupu ai le malic acid.
Furfural hydrogenation e mafai ona maua ai le furfuryl alcohol, tetrahydrofurfuryl alcohol, methyl furan, methyl tetrahydrofuran.
Furan e mafai ona faia mai furfural ausa ma vai ausa pe a uma decarburization ma catalyst talafeagai.
O le Furfural e feagai ma le Conicaro i lalo o le gaioiga o le alkali malosi e maua ai le furfuryl alcohol ma le sodium furoate.
Furfural e mafai ona faia le Boqin tali i lalo o le gaioiga o le gaʻo gaʻo masima poʻo le faʻavae oona ma faʻafefiloi ma le acid anhydride e fausia ai le furan acrylic acid.
Furfural ua condensed i phenolic compounds e maua ai resin thermoplastic; e fa'aputu i le urea ma le melamine e fai ai le palasitika; ma e fa'aputu i le acetone e fai ai le resini furfurone.
Fa'aoga Corncob
1. E mafai ona faʻaaogaina e aveese mai ai uʻamea mamafa mai le suavai leaga, ma e mafai ona faʻaaogaina e puipuia ai laupepa manifinifi vevela mai le pipii faʻatasi.
2. E mafai ona faʻaaogaina i le gaosiga o pepa malo, laupapa sima ma piliki sima, ma e mafai ona faʻaaogaina e fai ma faʻatumu mo kelu poʻo le faapipii.
3. E mafai ona faʻaaogaina e pei o meaʻai muamua, methionine, lysine, lysine protein paʻu, betaine, teuteuga eseese, vailaʻau faʻamaʻi, vitamini, phospholipids, phytase, mea manogi ma madurin, saogalemu Common enzyme choline chloride, ma isi mea, vailaʻau vailaʻau faʻasaina. , meaʻai meaʻai, e mafai ona suitulaga lona lua paʻu, ma o se tasi foi o mea autu autu mo le fermentation o mea ola.
4. Faʻaaogaina mo le gaosiga o furfural ma xylitol.

Fegalegaleai ma le faiga fou o furfural otaota ...
Pateni fou fou a le atunuu O uiga ma metotia o togafitiga o vai otaota furfural: E malosi malosi. O le vai lapisi pito i lalo o loʻo i ai le 1.2% ~ 2.5% acetic acid, lea e faʻafefe, khaki, moli uila <60%. I le faʻaopoopoga i le vai ma le acetic acid, o loʻo i ai foi se vaega itiiti o furfural, isi faʻasologa o meaola faʻalaʻau, ketones, ma isi.

Fa'agasologa ole gaosiga ole hydrogen peroxide
Fa'agasologa o le gaosiga o le hydrogen peroxide O le fua fa'atatau o le hydrogen peroxide o le H2O2, e masani ona ta'ua o le hydrogen peroxide. O foliga vaaia o se vai manino le lanu, o se oxidant malosi, o lona vaifofo vai e talafeagai mo le faʻamaʻi manuʻa faafomaʻi ma le faʻamaʻiina o le siosiomaga ma le faʻamaʻiina o meaʻai. I lalo o tulaga masani, o le a pala i le vai ma le okesene, ae o le iole pala ...
