1, {{4- butanediol (BDO), yog cov kab muaj ntxhiab tsw qab, yog cov khoom siv tsw qab, yog cov khoom siv ua tsis muaj kob, yog cov qauv ua kom tsis muaj kob, yog cov qauv ua kom zoo nkauj siv ntau yam transformations, ua rau nws muaj ntau yam intermediate .
Qhia txog 1, 4- butanediol
1, {{4- butanediol (BDO), yog cov kab muaj ntxhiab tsw qab, yog cov khoom siv tsw qab, yog cov khoom siv ua tsis muaj kob, yog cov qauv ua kom tsis muaj kob, yog cov qauv ua kom zoo nkauj Kev hloov pauv ntau yam kev hloov pauv, ua rau nws muaj ntau yam nyob hauv dej thiab solubicity nyob rau hauv cov txheej txheem tswj hwm ib puag ncig, saib xyuas nws lub luag haujlwm nyob rau hauv cov txheej txheem tswj hwm ib puag ncig, yooj yim {{{7} {}
Kev tsim tawm tswv yim: los ntawm petrochemicals rau cov kev coj ua bio
Kev lig kev cai, BDO yog synthesized los ntawm cov txheej txheem REPPE, muaj kev txhawj xeeb txog cov kab mob ntau dua los ntawm kev kub ntxhov, xws li pob kws lossis kab nrib pleb, mus rau hauv BDDO . cov tuam txhab zoo li genomatica muaj kev vam meej ntawm cov txheej txheem hydralicts, txhim kho cov txheej txheem ntawm hydrogracy thiab kev txo cov hluav taws xob thiab kev ua haujlwm ntawm kev tsim hluav taws xob .
Cov Nta Tshwj Xeeb: dhau ntawm cov khoom tseem ceeb
BDO cov pab pawg Hydroxyl pab txhawb kev sib txuas ua ke (LD₅₀) metabolized rau gamma-hydroxybutyrate (GB), nws sib tshuam nrog kev tshawb nrhiav microbratory, nrog cov qauv microbravity, nrog cov qauv hluav taws xob tsis ntev los no, ua raws li kev lag luam kev lag luam ncig.
Cov Ntawv Thov: Tsoos thiab Txiav-Ntug
O● Polymer Kev Lag Luam: BDO yog pivotal nyob rau hauv kev tsim Spandex (Elastane) thiab polybutylene terhabtive (PBT)
● Zog cia: Qhov kev tshawb fawb tshwm sim los tshawb fawb BDDO raws electrolytes hauv cov roj teeb lithium-ion, kev txhim kho ion condability thiab thermal ruaj khov, qhov tseem ceeb rau cov tsheb hluav taws xob {2}
● Chaw ua tshuaj: Raws li ib tug prefursor rau tetrahydrofuran (Thf), BDO AIDSzes hauv kev ua haujlwm ntawm kev siv tshuaj tua kab mob rau biocompatibility.
● Kev siv kev sib cav: Tsis yooj yim hloov dua siab tshiab rau GHB tau coj mus rau txoj kev tswj kev nruj, nrog kev pom tiag tiag tam sim no tau xa mus rau cov khoom ua adulterated {}}
Kev tswj hwm thiab kev nyab xeeb Dynamics
Cov kev cai thoob ntiaj teb Vis: U {.}}}} {{4 4} {teev} teev Twa ntawm 5 ppm) hais txog Kev kho qhov cua thiab ppe {{{. Kev kho mob ib puag ncig muaj kev kho tsis zoo rau BDO, tsis pub muaj cov txiaj ntsig tsis ntev los no nrog tamper-Evident nta {}}
Kev txiav txim siab ib puag ncig thiab kev lag luam
Kev xaiv roj av uas yog cov khoom siv roj av ntxiv, txuas rau cov khoom lag luam roj av ntxiv, txuas mus rau cov khoom lag luam roj av. Cov peev txheej lag luam} BASF thiab DSM nthuav tawm cov khoom siv ntau lawm .
Yav Tom Ntej Frontiers: Ncaj Ncees thiab dhau
Kev tshawb fawb yog tshawb nrhiav cov microbes rau ntau dua cov khoom siv roj ntsha rau cov qauv sib tw pom BDO kev sib koom ua ke rau hauv biodegradable polymers, txo cov khib nyiab yas .
