Zachilengedwe 1,4- butanediol (BDO)

Chilinganizo maselo: C4H10O2
Maselo kulemera: 90.12
Makhalidwe:Ndi madzi opanda mafuta komanso owoneka bwino. Malo olimba ndi 20.1 C, malo osungunuka ndi 20.2 C, malo otentha ndi 228 C, kuchuluka kwake ndi 1.0171 (20/4 C), ndipo index ya refractive ndi 1.4461. Flash point (chikho) pa 121 C. Zosungunuka mu methanol, ethanol, acetone, yosungunuka pang'ono mu ether. Ndi yopanda pake komanso yopanda fungo, pomwe khomo lake ndi lokoma pang'ono.
Ubwino: Bio-based 1,4-butanediol imapangidwa kuchokera ku bio-based succinic acid ndi esterification, hydrogenation, kuyeretsedwa ndi njira zina ndipo zomwe zili ndi kaboni kaboni ndizoposa 80%. Mapulasitiki omwe amatha kusungunuka monga PBAT, PBS, PBSA ndi PBST ogwiritsa ntchito 1,4- butanediol ngati zopangira ndi mapulasitiki osungunuka, omwe akutsata kwathunthu miyezo ya zotsalira zazomera m'maiko osiyanasiyana.

Ntchito gawo

1,4- butanediol (BDO) ndichofunikira kwambiri popanga mankhwala. Amagwiritsidwa ntchito kwambiri pamagulu azachipatala, makampani opanga mankhwala, nsalu, kupanga mapepala, zamagalimoto komanso mafakitale azitsamba tsiku lililonse. Ndizofunikira zopangira polybutylene terephthalate (PBT) zomangamanga mapulasitiki ndi CHIKWANGWANI cha PBT. Ndizofunikira zopangira zopanga PBAT, PBS, PBSA, PBST ndi zina zotero.
