1,4- butanediol (BDO) ma muli o ka bio.

Molecular haʻilula: C4H10O2
Kaumaha Molecular: 90.12
Ano:He kala ʻole a viscous aila wai. ʻO 20.1 C ke kiko paʻa, ʻo 20.2 C ke kiko hoʻoheheʻe, ʻo 228 C ke kiko e hoʻolapalapa ai, ʻo 1.0171 (20/4 C) ka nui, a ʻo ka index index is 1.4461. Kihi kukuna (kīʻaha) ma 121 C. Hiki ke hoʻoheheʻe ʻia i ka methanol, ethanol, acetone, soluble iki i ka ether. He hygroscopic a ʻaʻala ʻole ia, ʻoiai he ʻono iki ka puka.
Nā pōmaikaʻi: Hana ʻia ʻo 1,4-butanediol i hoʻokumu ʻia i ka bio mai ka acid acid succinic i hoʻokumu ʻia e ka esterification, hydrogenation, hoʻomaʻemaʻe a me nā hana ʻē aʻe aʻoi aku ka nui o ka bio-carbon ma mua o 80%. ʻO nā meaola biodegradable e like me PBAT, PBS, PBSA a me PBST e hoʻohana ana i 1,4- butanediol e like me nā mea maka he mau meaola biodegradable maoli ia, e pili pono ana i ke ana o ka biomass ma nā ʻāina like ʻole.

Kahua noi

1,4- butanediol (BDO) kahi meaola a me nā mea waiwai kemika maikaʻi. Hoʻohana nui ʻia ia i nā ʻano lāʻau lapaʻau, ʻoihana kemika, lole, papermaking, kaʻa a me ka ʻoihana kemika o kēlā me kēia lā. ʻO ia nā mea waiwai no ka hana ʻana o polybutylene terephthalate (PBT) ʻenehana plastics a me ka fiber PBT. ʻO ia ka mea maka e pono ai no ka hana ʻana i kahi biastegradable plast PBAT, PBS, PBSA, PBST a pēlā aku.
