Bio-based 1,4- butanediol (BDO)

Cov mis mos: C4H10O2
Lub cev nyhav: 90.12
Cov yam ntxwv:Nws tsis muaj kob uas muaj kua thiab nrog kua nyeem roj. Lub ntsiab lus tseem ceeb yog 20.1 C, lub ntsiab lus melting yog 20.2 C, qhov taw tes kub yog 228 C, qhov ntsuas tus txheeb ze yog 1.0171 (20/4 C), thiab qhov ntsuas qhov taw qhia yog 1.4461. Flash point (khob) ntawm 121 C. Soluble hauv methanol, ethanol, acetone, soluble me ntsis hauv ether. Nws yog hygroscopic thiab ntxhiab, thaum nkag yog me ntsis qab zib.
Cov txiaj ntsig zoo: Bio-based 1,4-butanediol yog tsim los ntawm cov kua qaub-succinic acid los ntawm esterification, hydrogenation, kev ua kom huv thiab lwm cov txheej txheem thiab cov ntsiab lus ntawm bio-carbon ntau dua 80%. Lub tshuab biodegradable xws li PBAT, PBS, PBSA thiab PBST siv 1,4- butanediol li cov khoom siv raw yog tiag tiag biodegradable plastics, uas tau ua tiav raws cov qauv ntawm biomass hauv ntau lub teb chaws.

Thov teb

1,4- butanediol (BDO) yog qhov tseem ceeb ntawm cov organic thiab cov khoom siv tshuaj lom neeg zoo. Nws yog dav siv hauv kev lag luam tshuaj, tshuaj lom neeg kev lag luam, textile, papermaking, tsheb thiab tshuaj txhua hnub kev lag luam. Nws yog qhov pib raw khoom rau cov khoom siv polybutylene terephthalate (PBT) engineering plastics thiab PBT fiber. Nws yog cov khoom siv tseem ceeb rau kev tsim cov biodegradable plast PBAT, PBS, PBSA, PBST thiab lwm yam.
