Bio-yakavakirwa 1, 4-butanediol (BDO)

Tsananguro Pfupi:

Bio-based 1,4-butanediol inogadzirwa kubva kune bio-based succinic acid kuburikidza nemaitiro senge esterification, hydrogenation, uye kuchenesa. Iyo bio-kabhoni yezvinhu inosvika zvinopfuura makumi masere muzana. Uchishandisa bio-based 1,4-butanediol kunge mbishi zvinhu, mapurasitiki anogadziriswa zvigadzirwa PBAT, PBS, PBSA, PBST uye zvimwe zvigadzirwa zvinogadzirwa ndezvechokwadi mapurasitiki anodzikisira biomass uye anoteedzana zvizere neepasi rose biomass zvemukati zviyero.

Bio-yakavakirwa 1,4- butanediol (BDO)

Molecular fomura: C4H10O2
Molecular uremu: 90.12
Hunhu:Haina kuchena uye viscous oiri mvura. Iyo solidification poindi ndeye 20.1 C, iyo inonyungudika ndeye 20.2 C, iyo yekubikira iri 228 C, huwandu hwehukama i1.0171 (20/4 C), uye iyo refractive index iri 1.4461. Flash poindi (mukombe) pa121 C. Inonyungudika mumethanol, ethanol, acetone, yakanyungudika zvishoma muether. Iyo hygroscopic uye isina hwema, nepo mukova uchitapira zvishoma.
Zvakanakira: Bio-yakavakirwa 1,4-butanediol inogadzirwa kubva kune bio-based succinic acid ne esterification, hydrogenation, kuchenesa uye mamwe maitiro uye izvo zvirimo bio-kabhoni inopfuura 80%. Mapurasitiki anogadzirwa nehutachiona akadai sePBAT, PBS, PBSA uye PBST achishandisa 1,4- butanediol seye mbishi zvinhu zvinogadzirwa nemapurasitiki anonyatso kuora, ayo anoenderana zvizere neyakajairwa biomass munyika dzakasiyana siyana.

Yekushandisa munda

1,4- butanediol (BDO) yakakosha organic uye yakanaka chemakemikari mbishi zvinhu. Inoshandiswa zvakanyanya muminda yemishonga, indasitiri yemakemikari, machira, kugadzira mapepa, mota uye zuva nezuva maindasitiri emakemikari Iyo ndiyo yakakosha mbishi yekugadzira polybutylene terephthalate (PBT) mainjiniya epurasitiki uye PBT fiber. Iyo ndiyo inodiwa mbishi yekugadzira biodegradable plast PBAT, PBS, PBSA, PBST zvichingodaro.
