Chisonkho cha chimanga ndi furfural zimapanga njira yopangira furfural
Chidule
Zomwe zili ndi ulusi wa Pentosan (monga chitsononkho cha chimanga, zipolopolo za mtedza, mbewu za thonje, matumba a mpunga, utuchi, nkhuni za thonje) zitha hydrolysis kukhala pentose molingana ndi kutentha kwina ndi chothandizira, Pentose amasiya mamolekyu atatu amadzi kuti apange furfural.
Chisonkho chimanga ntchito ndi zipangizo kawirikawiri, ndipo pambuyo mndandanda wa ndondomeko monga Kuyeretsa, kuphwanya, ndi asidi hydrolysis, phala distillation, neutralization, dewatering, kuyenga kupeza furfural oyenerera pamapeto.
"Zinyalala" zidzatumizidwa ku kuyaka kwa boiler, phulusa lingagwiritsidwe ntchito ngati zinthu zodzazidwa ndi zomangamanga kapena organic.
Chachitatu, ndondomeko yoyendera:
Chemical chilengedwe
Chifukwa furfural ili ndi magulu ogwiritsira ntchito aldehyde ndi dienyl ether, furfural imakhala ndi ma aldehydes, ethers, dienes ndi mankhwala ena, makamaka ofanana ndi benzaldehyde. Pazifukwa zina, furfural imatha kuchitika motere:
Furfural ndi oxidized kupanga maleic acid, maleic anhydride, furoic acid, ndi furanic acid.
Mu gawo la mpweya, furfural imapangidwa ndi okosijeni ndi chothandizira kuti apange anhydrous malic acid.
Furfural hydrogenation imatha kupanga mowa wa furfuryl, mowa wa tetrahydrofurfuryl, methyl furan, methyl tetrahydrofuran.
Furan ikhoza kupangidwa kuchokera ku nthunzi ya furfural ndi nthunzi yamadzi pambuyo pa decarburization ndi chothandizira choyenera.
Furfural amakumana ndi Conicaro reaction pansi pa mphamvu ya alkali kuti apange furfuryl mowa ndi sodium furoate.
Furfural akhoza kukumana Boqin anachita pansi pa zochita za mafuta asidi mchere kapena organic m'munsi ndi condense ndi asidi anhydride kupanga furan acrylic asidi.
Furfural ndi condensed ndi phenolic mankhwala kupanga thermoplastic resin; imapangidwa ndi urea ndi melamine kupanga pulasitiki; ndipo imafupikitsidwa ndi acetone kupanga utomoni wa fufurone.
Corncob amagwiritsa ntchito
1. Ikhoza kugwiritsidwa ntchito kuchotsa zitsulo zolemera m'madzi otayira, ndipo ingagwiritsidwe ntchito kuteteza mapepala otentha otentha kuti asamamatirane.
2. Itha kugwiritsidwa ntchito popanga makatoni, bolodi la simenti ndi njerwa za simenti, ndipo itha kugwiritsidwa ntchito ngati chodzaza ndi guluu kapena phala.
3. Itha kugwiritsidwa ntchito ngati chakudya premix, methionine, lysine, lysine mapuloteni ufa, betaine, zosiyanasiyana nkhungu kukonzekera, antifungal wothandizira, mavitamini, phospholipids, phytase, flavoring wothandizira ndi madurin, chitetezo Common enzyme choline kolorayidi, etc., Chowona Zanyama mankhwala zowonjezera , zonyamulira zopatsa thanzi, zimatha kulowa m'malo ufa wachiwiri, komanso ndi chimodzi mwazinthu zazikulu zopangira nayonso mphamvu yachilengedwe. mankhwala.
4. Amagwiritsidwa ntchito pokonza furfural ndi xylitol.

Kuthana ndi njira yatsopano yowonongera zinyalala ...
National Invention Patent Makhalidwe ndi njira yochizira madzi otayira a furfural: Ali ndi acidity yolimba. Madzi otayira pansi amakhala ndi 1.2% ~ 2.5% acetic acid, yomwe ndi turbid, khaki, transmittance light <60%. Kuphatikiza pa madzi ndi asidi acetic, mulinso kwambiri Kachulukidwe kakang'ono ka furfural, trace organic acids, ketones, ndi zina zotero. COD m'madzi oipa ndi pafupifupi 15000 ~ 20000mg/L...

Njira yopanga haidrojeni peroxide
Njira yopangira haidrojeni peroxide Njira yopangira hydrogen peroxide ndi H2O2, yomwe imadziwika kuti hydrogen peroxide. Maonekedwe ndi madzi owonekera opanda mtundu, ndi oxidant amphamvu, yankho lake lamadzi ndi loyenera kupha tizilombo toyambitsa matenda komanso kupha tizilombo toyambitsa matenda komanso tizilombo toyambitsa matenda. Munthawi yabwinobwino, imawola kukhala madzi ndi mpweya, koma makoswe akuwola ...
