Astaamaha:Waa mid aan midab lahayn oo dareeraha saliida leh. Qodobka adkeynta ayaa ah 20.1 C, barta dhalaalaysa waa 20.2 C, barta kuleylka waa 228 C, cufnaanta qaraabada waa 1.0171 (20/4 C), tusmada soocelinta waa 1.4461. Bar dhibic (koob) oo ku taal 121 C. Ku milma methanol, ethanol, acetone, wax yar ku milma ether. Waa hygroscopic iyo ur la'aan, halka iridda wax yar macaan.
Faa'iidooyinka: Bio-based 1,4-butanediol waxaa laga sameeyaa bio-based succinic acid iyadoo la adeegsanayo esterification, hydrogenation, daahirinta iyo habab kale iyo waxyaabaha ku jira bio-carbon-ka ayaa ka badan 80%. Balastigyada wax baabi'in kara sida PBAT, PBS, PBSA iyo PBST iyagoo adeegsanaya 1,4- butanediol maadama ceyriinku yahay balaastig biodigradable, oo si buuxda ugu habboon heerka biomass ee dalal kala duwan.

Goobta arjiga

1,4- butanediol (BDO) waa shey muhiim ah oo ceyriin iyo ganaax kiimiko ceyriin ah. Waxaa si weyn loogu isticmaalaa dhinacyada caafimaadka, warshadaha kiimikada, dharka, sameynta waraaqaha, baabuurta iyo warshadaha kiimikada maalinlaha ah. Waa alaabta ceeriin ee aasaasiga ah ee wax soo saarka polybutylene terephthalate (PBT) caagagga injineernimada iyo fiber PBT. Waa alaabta ceyriinka ah ee lagama maarmaanka u ah soosaarka balastarka biodegradable PBAT, PBS, PBSA, PBST iyo wixii la mid ah.
