Hoʻopuka ka Furfural a me ka cob kulina i ka hana furfural
Hōʻuluʻulu manaʻo
ʻO nā mea kanu fiber Pentosan (e like me ka Corn cob, ka pīnī pīnī, ka hull o ka pulupulu, ka hull raiki, ka sawdust, ka lāʻau pulupulu) e hydrolysis i loko o ka pentose i ka fluence o ka mahana a me ka catalyst, waiho nā Pentoses i ʻekolu mau mole wai e hana ai i furfural.
Hoʻohana ʻia ka ʻōpala kulina e nā mea maʻamau, a ma hope o ke kaʻina hana e hoʻomaʻemaʻe ai, ʻokiʻoki, me ka hydrolysis acid, mash distillation, neutralization, dewatering, hoʻomaʻemaʻe loaʻa i ka furfural kūpono i ka hopena.
E hoʻouna ʻia ka "Waste" i ka hoʻopau ʻana i ka paila, hiki ke hoʻohana ʻia ka lehu i mea hoʻopiha piha no ka ʻoihana
ʻO ke kolu, ʻo ka papa kuhikuhi kaʻina hana:
ʻAno kemika
No ka mea he mau pūʻulu hana aldehyde a me dienyl ether ka furfural, loaʻa i ka furfural nā waiwai o nā aldehydes, ethers, dienes a me nā pūhui ʻē aʻe, ʻoi aku ka like me benzaldehyde. Ma lalo o kekahi mau kūlana, hiki i ka furfural ke hana i nā hopena kemika penei:
Hoʻopili ʻia ka Furfural e hana i ka maleic acid, maleic anhydride, furoic acid, a me furanic acid.
I ka manawa kinoea, ua hoʻoneʻe ʻia ka furfural e kahi catalyst e hoʻohua i ka waika malic anhydrous.
Hiki i ka Furfural hydrogenation ke hana i ka furfuryl alcohol, tetrahydrofurfuryl alcohol, methyl furan, methyl tetrahydrofuran.
Hiki ke hana ʻia ʻo Furan mai ka mahu furfural a me ka mahu wai ma hope o ka decarburization me ka catalyst kūpono.
Loaʻa ka Furfural i ka hopena Conicaro ma lalo o ka hana o ka alkali ikaika e hana i ka waiʻona furfuryl a me ka sodium furoate.
Hiki i ka Furfural ke hana i ka hopena Boqin ma lalo o ka hana o ka paʻakai paʻakai momona a i ʻole ke kumu kūlohelohe a condense me ka acid anhydride e hana ai i ka furan acrylic acid.
Hoʻopili ʻia ka Furfural me nā pūhui phenolic e hana i ka resin thermoplastic; ua hoʻopili ʻia me ka urea a me ka melamine e hana i ka plastic; a ua condensed me ka acetone e hana furfurone resin.
Hoʻohana ʻo Corncob
1. Hiki ke hoʻohana ʻia e unuhi i nā metala koʻikoʻi mai ka wai ʻino, a hiki ke hoʻohana ʻia e pale i nā ʻāpana kila lahilahi wela mai ka pili pū ʻana.
2. Hiki ke hoʻohanaʻia i ka hanaʻana i ka pepa pahu, ka papa sima a me ka pōhaku lepo, a hiki ke hoʻohanaʻia e like me ka mea hoʻopihapiha no ke kāpili a paʻi paha.
3. Hiki ke hoʻohana ʻia e like me ka meaʻai premix, methionine, lysine, lysine protein pauka, betaine, nā ʻano hoʻomākaukau mold, antifungal agents, vitamina, phospholipids, phytase, flavoring agents a me madurin, palekana Common enzyme choline chloride, etc., veterinary drug additives , nā mea lawe meaʻai, hiki ke hoʻololi i ka pauka lua, a ʻo ia kekahi o nā mea waiwai nui no ka fermentation o huahana olaola.
4. Hoʻohana ʻia no ka hana ʻana i ka furfural a me ka xylitol.

Ke hana nei me ka hana hou o ka ʻōpala furfural ...
ʻO nā ʻano a me ke ʻano o ka mālama ʻana i ka wai ʻōpala furfural: He ʻakika ikaika kona. Aia ka wai ʻōpala i lalo he 1.2% ~ 2.5% acetic acid, he turbid, khaki, māmā transmittance <60%. Ma waho aʻe o ka wai a me ka acetic acid, loaʻa nō hoʻi kahi liʻiliʻi o ka furfural, nā ʻāpana ʻokoʻa ʻē aʻe, nā ketones, a me nā mea ʻē aʻe.

ʻO ke kaʻina hana hydrogen peroxide
ʻO ke kaʻina hana o ka hydrogen peroxide ʻO H2O2, ʻike nui ʻia ʻo ka hydrogen peroxide. ʻO ka hiʻohiʻona he wai aniani ʻaʻohe kala, he mea oxidant ikaika, kūpono kāna ʻano wai no ka disinfection ʻeha olakino a me ka disinfection kaiapuni a me ka disinfection meaʻai. Ma lalo o nā kūlana maʻamau, e decompose ia i loko o ka wai a me ka oxygen, akā ʻo ka ʻiole decomposition ...
