Ka hoʻohana ʻana i ka butanediol i nā mea hoʻonaninani
ʻO Butanediol, ka nui o ka acetylene a me ka formaldehyde e like me nā mea maka.Hoʻohana ʻia ia e like me ka mea hoʻonui kaulahao no ka hana ʻana i ka polybutylene terephthalate a me ka polyurethane, a ma ke ʻano he kumu waiwai nui no ka tetrahydrofuran, γ-butyrolactone, lāʻau lapaʻau a me ka synthesis organik.No ka mea ʻo polybutylene terephthalate kahi ʻano polyester me nā waiwai maikaʻi, ke piʻi wikiwiki nei ke koi no nā plastics engineering.

He lāʻau kemika ʻona loa - propargyl alcohol
ʻO Propargyl Alcohol, molecular formula C3H4O, molecular weight 56. ʻO ka wai alohilohi kala ʻole, ʻoluʻolu me ke ʻala ʻala, ʻawaʻawa, ʻeha nui i ka ʻili a me nā maka.He mea waena ma ka hoʻohui ʻana.Hoʻohana nui ʻia no ka synthesis o nā lāʻau antibacterial a me nā anti-inflammatory sulfadiazine;Ma hope o ka hydrogenation hapa, hiki i ka waiʻona propylene ke hana i ka resin, a ma hope o ka hydrogenation piha, hiki ke hoʻohana ʻia ka n-propanol ma ke ʻano he mea maka o ka lāʻau anti-tuberculosis ethambutol, a me nā huahana kemika a me nā lāʻau lapaʻau.Hiki ke pale i ka waikawa i ka hao, ke keleawe a me ka nickel a me nā metala ʻē aʻe, hoʻohana ʻia e like me ka wehe ʻana i ka ʻōpala.Hoʻohana nui ʻia i ka ʻili ʻaila.Hiki ke hoʻohana ʻia e like me ka solvent, stabilizer o nā hydrocarbons chlorinated, herbicide a me nā insecticide.Hiki ke hoʻohana ʻia no ka hana ʻana i ka waikawa acrylic, acrolein, 2-aminopyrimidine, γ-picauline, vitamin A, stabilizer, corrosion inhibitor a pēlā aku.
Nā inoa ʻē aʻe: propargyl alcohol, 2-propargyl – 1-alcohol, 2-propargyl alcohol, propargyl alcohol acetylene methanol.

E polymerize a pahū ka Propargyl
Hoʻokumu ʻia ke kaʻina hana mua ma luna o ka waiʻona propargyl e like me ka solvent, KOH ma ke kumu, ka hopena wela e loaʻa ai ka pahuhopu.ʻO ka hopena me ka ʻole o ka solvent dilution kūlana e emi nā mea haumia, ʻoi aku ka maʻemaʻe o ka hopena.
Ke noʻonoʻo nei i ka polymerization catalytic a me ka decomposition pahū o nā alkynes terminal, ua komo ʻo Amgen's Hazard Evaluation Lab (HEL) e hana i nā loiloi palekana a kōkua i ke kaʻina hana ma mua o ka piʻi ʻana i 2 lita o ka hopena.
Hōʻike DSC ho'āʻo i ka hopena hoʻomaka e decompose ma 100 °C a me ka hoʻokuʻu 3667 J/g ikehu, oiai propargyl ka waiʻona a me KOH pu, oiai ka ikehu hāʻule i 2433 J/g, akā, i ka decomposition mahana no hoi kulu i 85 °C, a. kokoke loa ka mahana o ke kaʻina hana i 60 °C, ʻoi aku ka nui o ka pilikia.

1,4-butanediol (BDO) a me kāna hoʻomākaukau ʻana i ka PBAT plastic biodegradable
1, 4-butanediol (BDO);ʻO ka PBAT he plastic biodegradable thermoplastic, he copolymer o butanediol adipate a me butanediol terephthalate.Loaʻa iā ia nā hiʻohiʻona o PBA (polyadipate-1, 4-butanediol ester diol) a me PBT (polybutanediol terephthalate).Loaʻa iā ia ka ductility maikaʻi a me ka elongation i ka wā hoʻomaha, a me ke kūpaʻa wela maikaʻi a me ka hana hopena.Eia kekahi, he biodegradability maikaʻi loa ia a ʻo ia kekahi o nā mea biodegradable kaulana loa i ka noiʻi ʻana i nā plastic biodegradable a me ka noi maikaʻi loa ma ka mākeke.

Hana ʻia o 1, 4-butanediol (BDO) ma ke ʻano maleic anhydride
ʻElua mau kaʻina hana nui no ka hana ʻana o BDO e maleic anhydride.ʻO kekahi ke kaʻina hana hydrogenation pololei o maleic anhydride i hoʻomohala ʻia e Mitsubishi Petrochemical a me Mitsubishi Chemical ma Iapana i ka makahiki 1970, kahi i hōʻike ʻia e ka hana like ʻana o BDO, THF a me GBL i ke kaʻina hydrogenation o maleic anhydride.Hiki ke loaʻa nā huahana o nā mele like ʻole ma ka hoʻoponopono ʻana i nā kūlana kaʻina.ʻO ka mea ʻē aʻe ke kaʻina hana hydrogen esterification o ka maleic anhydride i hoʻomohala ʻia e UCC Company a me Davey Process Technology Company ma United Kingdom, i hoʻomohala ʻia mai ka ʻenehana carbonyl synthesis haʻahaʻa.I ka makahiki 1988, ua hoʻopau ʻia ka loiloi hou ʻana o ke kaʻina hana a ua manaʻo ʻia ka hoʻolālā ʻoihana.I ka makahiki 1989, ua hoʻololi ʻia ka ʻenehana i DongSANG CHEMICAL COMPANY o Korea a me DONGGU CHEMICAL Company o Iapana e kūkulu i kahi 20,000-TON / makahiki 1, 4-BUtanEDIOL INDUSTRIAL production PLANT.
