Nyob rau lub sijhawm uas lub ntiaj teb tab tom xyaum ua lub tswv yim ntawm kev txhim kho kom ruaj khov thiab ua txhua yam kev rau siab kom ua tiav lub hom phiaj "ob chav carbon", furandiformic acid (FDCA) tau tshwm sim ua lub hnub qub tshiab ci ntsa iab hauv kev lag luam ntawm cov khoom siv bio-based, qhib lub qhov rooj tshiab rau yav tom ntej ntsuab rau peb.
Furanediformic acid, ua ib yam khoom dawb, yaj tau hauv dej thiab cov organic solvents xws li cawv thiab esters. Nws muaj cov yam ntxwv ntawm biodegradability, muaj zog rhiab heev thiab ruaj khov tshuaj lom neeg zoo. Nws tsis yog tsuas yog ib qho tshuaj lom neeg zoo hauv bio-based xwb, tab sis kuj yog ib qho ntawm cov qauv tseem ceeb rau kev ua tau zoo thiab cov ntaub ntawv polymer muaj nqis ntxiv. Nws cov kev ua tau zoo hauv ntau qhov chaw tseem ceeb yog kev sau dua tshiab ntawm kev lag luam thiab coj cov cib fim thiab kev hloov pauv tsis tau muaj dua los rau ntau lub koom haum.
Los ntawm kev saib xyuas kev tiv thaiv ib puag ncig, furanediformic acid muaj cov txiaj ntsig zoo tshaj plaws. Kev tsim cov polyester ib txwm muaj nyob ntawm cov khoom siv raw petrochemical, xws li terephthalic acid (PTA). Tag nrho cov txheej txheem tsim khoom tsis yog tsuas yog siv ntau cov roj av uas tsis rov ua dua tshiab xwb tab sis kuj tso tawm ntau cov pa roj carbon dioxide, ua rau muaj kev nyuaj siab rau ib puag ncig ecological. Kev yug los ntawm furanediformic acid tau rhuav tshem qhov kev tuag no tag nrho. Nws siv cov biomass rov ua dua tshiab ua cov khoom siv raw, txo kev vam khom roj los ntawm qhov chaw thiab txo cov pa roj carbon dioxide. Raws li cov ntaub ntawv tshaj lij, polyethylene glycol 2, 5-furanediformate (PEF) cov ntaub ntawv synthesized los ntawm furanediformic acid tuaj yeem txo qhov "carbon footprint" thoob plaws lawv lub neej tag nrho piv rau cov ntaub ntawv PET ib txwm muaj, txhaj tshuaj muaj zog rau hauv kev txhim kho ntsuab thiab ruaj khov ntawm lub ntiaj teb. Cov yam ntxwv no ua rau furandiformic acid yog cov khoom siv nyiam rau ntau lub tuam txhab hauv lawv txoj kev nrhiav kev hloov pauv kev tiv thaiv ib puag ncig, ua kom zoo txhawb kev hloov pauv tob ntawm ntau yam kev lag luam mus rau cov qauv tsim khoom ntsuab. Hauv cov nqe lus ntawm kev ua tau zoo, furanediformic acid kuj tseem ceeb heev. Nws muaj cov qauv molecular zoo ib yam li cov roj av monomer terephthalic acid (PTA), ob qho tib si muaj aromaticness ntawm lub cyclic conjugated system thiab ob qho tib si muaj ob pawg hydroxyl, uas ua rau lawv zoo sib xws heev hauv cov khoom siv lub cev thiab tshuaj. Txawm li cas los xij, lub nplhaib furan ntawm furanediformic acid yog cov qauv heterocyclic, thiab cov qauv tshwj xeeb no muab nws nrog tus yam ntxwv ntawm kev yooj yim degradable hauv xwm dua li lub nplhaib benzene. Lub caij no, los ntawm kev sib xyaw polymerization nrog monomers xws li diols thiab diamines, furanediformic acid tuaj yeem siv los npaj cov polyester, polyamide thiab lwm yam khoom siv bio-based polymer synthetic tshiab uas muaj cov tshuaj aromatic. Siv cov khoom PEF ua piv txwv. Nws cov khoom thaiv tiv thaiv ntau yam roj muaj zog dua li cov khoom siv PET ib txwm muaj. Tib lub sijhawm, nws muaj lub zog kho tshuab siab dua thiab tuaj yeem tsim cov khoom ntim nrog cov phab ntsa nyias dua. Qhov no tsis tsuas yog txhim kho kev ua tau zoo ntawm cov khoom, tab sis kuj txo qis kev siv cov khoom ntim, ua tiav ob lub hom phiaj ntawm kev txhim kho kev ua tau zoo thiab kev txuag cov peev txheej. Cov teb siv dav dav ntawm furanediformic acid ntxiv qhia txog nws tus nqi lag luam loj heev. Hauv kev lag luam ntawm cov ntaub ntawv ntim khoom, PEF cov ntaub ntawv, nrog lawv cov khoom zoo heev ntawm kev thaiv roj thiab lub zog kho tshuab, tuaj yeem tiv thaiv cov khoom noj, tshuaj, thiab lwm yam zoo dua, ntev lawv lub txee lub neej, thiab tib lub sijhawm txo qhov kev tsim cov khib nyiab ntim khoom, coj kev daws teeb meem tshiab rau kev lag luam ntim khoom ntsuab. Hauv kev lag luam ntawm cov ntaub textile, cov ntaub ntawv fiber los ntawm furanediformic acid muaj lub zog siab, modulus siab thiab kev tiv thaiv tshuaj zoo heev. Lawv tuaj yeem siv dav hauv cov khoom lag luam textile zoo nrog rau hauv cov teb tshwj xeeb xws li kev lag luam thiab kev tiv thaiv lub teb chaws, txhim kho qhov zoo thiab kev ua tau zoo ntawm cov khoom. Tsis tas li ntawd, furanediformic acid tau ua pov thawj tias muaj kev siv dav hauv ntau qhov chaw xws li kev ntim tshuaj, cov yas engineering, nylon, txheej, thiab cov yas ua kom zoo nkauj, thiab maj mam dhau los ua lub zog tseem ceeb uas tsav tsheb kev txhim kho thev naus laus zis thiab kev tsim khoom tshiab hauv ntau yam lag luam.
Nrog rau kev nce ntxiv ntawm kev saib xyuas thoob ntiaj teb rau kev txhim kho kom ruaj khov thiab kev thov ntau ntxiv rau cov khoom siv bio-based, kev ua lag luam rau furandiformic acid yog ci ntsa iab heev. Raws li cov koom haum tso cai kwv yees, los ntawm xyoo 2027, qhov loj ntawm kev ua lag luam ntawm FDCA yuav tshaj ib lab tons, nrog rau lub peev xwm ua lag luam loj heev. Tam sim no, ntau lub tuam txhab lag luam hauv tsev thiab txawv teb chaws uas paub zoo tab tom tsim kev lag luam furanediformic acid, nce kev nqis peev hauv kev tshawb fawb thiab kev txhim kho thiab kev tsim peev xwm. Piv txwv li, ua ib lub tuam txhab ua lag luam hauv kev lag luam thoob ntiaj teb ntawm cov khoom siv bio-based aromatic, Lifu Bio tau, tom qab ntau tshaj kaum xyoo ntawm kev tshawb fawb thiab kev txhim kho tsis tu ncua, tau tshawb nrhiav cov txheej txheem "Biomass glucose HMF FDCA" tshwj xeeb hauv ntiaj teb, tawg ntawm kev vam khom ntawm cov khoom siv bio-based furan rau ntawm cov khoom siv fructose uas tau los ntawm cov nplej. Xyoo 2022, nws tau ua tiav tso rau hauv kev ua haujlwm ntawm thawj kab FDCA 1,000-ton hauv ntiaj teb, thiab thaum lub Cuaj Hli 2024, nws tau pib tsim thawj kab FDCA 10,000-ton hauv ntiaj teb. Nrog kev nthuav dav thiab kev txhim kho zoo tas mus li, nws ua rau muaj kev txhim kho ntawm kev lag luam furan bio-based. Lub caij no, pab pawg los ntawm East China University of Science thiab Technology kuj tseem tab tom ua kev tshawb fawb txog "Biomass Conversion to Plastic Monomer - Furanediformic acid". Los ntawm kev tsim cov catalysts thiab cov txheej txheem rau kev tsim khoom tas mus li, lawv tau tsim txoj kev sib txuas lus tas mus li los ntawm glucose mus rau 2, 5-furanediformic acid, txhawb nqa kev nce qib ntawm cov thev naus laus zis furanediformic acid thiab kev txhim kho ntawm kev lag luam.
Furandiformic acid, ua ib yam khoom tseem ceeb hauv kev siv cov khoom siv bio-based, tab tom coj ntau yam kev lag luam mus rau lub sijhawm tshiab ntawm kev txhim kho ntsuab thiab ruaj khov nrog nws cov kev ua tau zoo tshaj plaws hauv kev tiv thaiv ib puag ncig, cov khoom siv lub cev thiab tshuaj lom neeg zoo heev, thiab kev siv dav dav. Nws tsis yog tsuas yog muab lub sijhawm zoo rau cov tuam txhab kom ua tiav kev hloov pauv kev tiv thaiv ib puag ncig thiab kev txhim kho khoom, tab sis kuj muab lub hauv paus ruaj khov rau peb los ua ke tiv thaiv peb lub ntiaj teb lub tsev thiab tsim lub neej yav tom ntej ci ntsa iab. Cia peb koom tes thiab txais yuav furanediformic acid, qhov kev cia siab tshiab no rau lub neej yav tom ntej ntsuab, nrog kev zoo siab, thiab ua ke tsim kom muaj kev ntsuab thiab vam meej dua tag kis!
