Furfural iyo galleydu waxay soo saaraan habka furfurnaanta
Soo koobid
Qalabka fiber-ka ee dhirta Pentosan ka kooban (sida Corn cob, qolof lawska, qolof abuur suuf ah, qolof bariiska, balka, alwaax suuf) waxay hydrolysis u geli doontaa pentose iyadoo la eegayo heerkul gaar ah iyo kicinta.
Cob galleyda waxaa isticmaala agabka sida caadiga ah, iyo ka dib habraac taxane ah oo ay ku jiraan Nadiifinta, burburinta, oo leh hydrolysis acid, mash distillation, dhexdhexaadin, nadiifin, nadiifin hel furfural u qalma dhamaadka.
"Qashinka" waxaa loo diri doonaa gubashada kuleyliyaha, dambaska waxaa loo isticmaali karaa sida walxaha la buuxiyey ee kaabayaasha ama organic
Saddexaad, jaantuska socodka geedi socodka:
Dabeecadda kiimikada
Sababtoo ah furfuralku wuxuu leeyahay aldehyde iyo dienyl ether functional groups, furfural wuxuu leeyahay sifooyinka aldehydes, ethers, dienes iyo xeryahooda kale, gaar ahaan la mid ah benzaldehyde. Xaalado gaar ah, furfural waxay la kulmi kartaa falcelinta kiimikaad ee soo socota:
Furfural waa oksaydhized si ay u soo saarto maleic acid, maleic anhydride, furoic acid, iyo furanic acid.
Marxaladda gaaska, furfural waxaa ogsaydhiyay kicinta si ay u dhaliso malic acid anhydrous.
hydrogenation Furfural waxay soo saari kartaa alkolada furfuryl, alkolada tetrahydrofurfuryl, methyl furan, methyl tetrahydrofuran.
Furan waxaa laga samayn karaa uumiga furfural iyo uumiga biyaha ka dib marka la gooyo oo leh kiciye habboon.
Furfural waxa ay martaa falcelinta Conicaro ee hoos timaada ficilka alkali xooggan si ay u soo saarto alkolada furfuryl iyo furoate sodium.
Furfural waxa ay ku dhici kartaa falcelinta Boqin iyada oo ay adeegsanayso milix aysiidh dufan leh ama saldhig organic ah oo ay ku ururiso anhydride acid si ay u samayso aashitada furan ee acrylic.
Furfural waxaa lagu ururiyaa xeryahooda phenolic si ay u soo saaraan resin thermoplastic; waxaa lagu shubaa urea iyo melamine si looga sameeyo caag; waxaana lagu shubaa acetone si uu u sameeyo burji furfurone.
Corncob waxay isticmaashaa
1. Waxaa loo isticmaali karaa in birta culus laga soo saaro biyaha wasakhda ah, waxaana loo isticmaali karaa in ay ka hortagto in ay isku dheggan yihiin birta dhuuban ee kulul.
2. Waxa loo isticmaali karaa samaynta kartoonada, looxa sibidhka iyo lebenka sibidhka, waxaana loo isticmaali karaa buuxinta xabagta ama koollada.
3. Waxaa loo isticmaali karaa sida premix feed, methionine, lysine, budada borotiinka lysine, betaine, diyaarinta caaryada kala duwan, wakiilada antifungal, fiitamiinada, fosfolipids, phytase, wakiilada dhadhanka iyo madurin, badbaadada Enzyme caadiga ah choline chloride, iwm, daroogooyinka xoolaha lagu daro. , sidayaal nafaqo, bedeli kara budada labaad, iyo sidoo kale waa mid ka mid ah alaabta ugu muhiimsan ee halsano. ee alaabta noolaha.
4. Waxa loo isticmaalaa habaynta furfuralka iyo xylitol.

La tacaalida habka cusub ee qashinka furfuralka...
Shatida hal-abuurka qaranka Sifooyinka iyo habka daawaynta ee biyaha wasakhda ah ee furfural: Waxay leedahay aysidh xoog leh. Biyaha wasakhda ah ee hoose waxay ka kooban yihiin 1.2% ~ 2.5% acetic acid, taas oo ah turbid, khaki, gudbinta iftiinka <60%. Marka lagu daro biyaha iyo aashitada acetic, waxa kale oo ku jira xaddi yar oo furfuraal ah, acids organic raad, ketones, iwm.

Habka wax soo saarka hydrogen peroxide
Habka soo saarista hydrogen peroxide Qaabka kiimikada ee hydrogen peroxide waa H2O2, oo badanaa loo yaqaan hydrogen peroxide. Muuqaalku waa dareere hufan oo aan midab lahayn, waa oksidant xooggan, xalkeeda aqueous wuxuu ku habboon yahay jeermiska nabarrada caafimaadka iyo jeermiska deegaanka iyo jeermiska cuntada. Xaaladaha caadiga ah, waxa ay u kala go'i doontaa biyo iyo ogsijiin, laakiin jiirka qudhunka...
