ʻO 1,4-Butanediol (BDO) (CAS: 110-63-4) he mea koʻikoʻi koʻikoʻi kemika a me nā mea hoʻonaninani maikaʻi, waena waena.ʻO ia ka hana ʻana o ka Polybutylene Terephthalate (PBT) mea kumu ʻenekinia plastics a me PBT fibers, a ʻo PBT plastic ka mea hoʻohiki maikaʻi loa o nā plastic engineering nui ʻelima.Hoʻohana ʻia ʻo 1,4-Butanediol i ka ʻoihana e like me ka solvent a i ka hana ʻana i kekahi mau ʻano plastics, elastic fibers a me polyurethanes.
Loaʻa ka 1,4-Butanediol mai ka butane ma ke kau ʻana i nā pūʻulu waiʻona ma kēlā me kēia hopena o kāna kaulahao mole a ʻo ia kekahi o nā isomers paʻa ʻehā o butanediol. no ka laʻana me nā waikawa dicarboxylic i nā polyesters, me nā diisocyanates i nā polyurethanes, a i ʻole me ka phosgene i ka polycarbonates.ʻO 1.4-Butanediol kahi kūlana kiʻekiʻe.Hoʻohana nui ʻia ʻo BDO a me kāna mau derivatives no ka hana ʻana i nā plastics, solvents, nā kemika uila a me nā fiber elastic.Eia kekahi, ʻo BDO kekahi poloka hale no ka synthesis o polyesterpolyols a me polyetherpolyols.
Hoʻohana ʻia ʻo Butanediol a me kāna mau derivatives i kahi ākea ākea o nā noi i ka ʻoihana kemika;i waena o nā mea ʻē aʻe i ka hana ʻana i nā plastic plastic, polyurethanes, solvents, kemika uila a me nā fiber elastic.
Hoʻohana ʻia ka 1,4-Butanediol i ka synthesis o epothilones, kahi papa hou o nā lāʻau lapaʻau maʻi maʻi.Hoʻohana pū ʻia i ka stereoselective synthesis o (-) -Brevisamide.
ʻO 1,4-Butanediol ka hoʻohana nui loa i loko o ka hana tetrahydrofuran (THF), i hoʻohana ʻia e hana i ka polytetramethylene ether glycol, ka mea e hele nui i loko o ka spandex fibers, urethane elastomers, a me copolyester ethers.
Hoʻohana pinepine ʻia ʻo 1,4-Butanediol ma ke ʻano he solvent i ka ʻoihana kemika e hana i ka gamma-butyrolactone a me nā fiber elastic e like me spandex.
Hoʻohana ʻia ia ma ke ʻano he mea hoʻopili keʻa no nā urethanes thermoplastic, polyester plasticizers, pena a me nā uhi.
1,4-Butanediol undergoes dehydration i mua o ka phosphoric acid yielded teterahydrofuran, he mea hoʻoheheʻe koʻikoʻi i hoʻohana ʻia no nā noi like ʻole.
Hana ʻo 1,4-Butanediol i waena a hoʻohana ʻia e hana i ka polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) a me ka polyurethane (PU).
Loaʻa ka 1,4-Butanediol i ka hoʻohana ʻana ma ke ʻano he mea hoʻomaʻemaʻe ʻoihana a me kahi mea hoʻopau kepau.
Hoʻohana ʻia ʻo 1,4-Butanediol e like me ka plasticiser (e laʻa i nā polyesters a me nā cellulosic), ma ke ʻano he mea hoʻoheheʻe lawe i ka paʻi ʻana i ka ʻīnika, kahi mea hoʻomaʻemaʻe hoʻomaʻemaʻe, kahi mea hoʻopili (ma ka ʻili, plastics, polyester laminates a me nā kāmaʻa polyurethane), i ka mahiʻai a me nā holoholona. nā mea kemika a me nā mea hoʻonani (i nā pena, nā varnish a me nā kiʻiʻoniʻoni).
Ea a me ka wai Hiki ke ahi.He hygroscopic ka 1,4-Butanediol.Hiki ke hoʻoheheʻe wai.
Hōʻike Hōʻike 1,4-Butanediol ka wela a me ka māmā.Hoʻopili ka 1,4-Butanediol me nā chlorides acid, anhydride acid a me nā chloroformates;hoʻopili me nā mea hoʻoheheʻe a me nā mea hoʻemi.ʻAʻole kūpono ka 1,4-Butanediol me nā isocyanates a me nā waikawa;ʻAʻole kūpono pū me nā peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide a me ka chlorine.
Pilikia ma ka ʻai ʻana.
Pilikia Ola He maʻalahi nā hopena ʻawaʻawa.ʻO 1,4-Butanediolis ʻaʻohe mea ʻawaʻawa ma mua o kāna mau mea like ʻole, butenediol a me ka butynediol.ʻO ka waiwai oralLD50 i nā ʻiole keʻokeʻo a me ka guinea pigsis ~2 mL/kg.ʻO nā hōʻailona ʻawaʻawa mai ka ʻai ʻana e komo pū me ka hauʻoli, ke kaumaha o ka ʻōnaehana nerve waena, nausea, a me ka hiamoe.
ʻO ka ʻai ʻana i nā mea nui e pono ai e hoʻopuka i nā hōʻailona.
ʻO ke ahi ʻaʻole hiki ke hoʻā ʻia ka wai, ke kiko uila (ke kīʻaha hāmama) 121℃.
Palekana Palekana He lāʻau make kanaka ma ke ala i ʻike ʻole ʻia.ʻAi ʻona ma ka ʻai ʻana a me nā ala intraperitoneal.Nā hopena ʻōnaehana kanaka: hoʻololi ʻia ka manawa hiamoe.Hiki ke puhi ʻia ke ʻike ʻia i ka wela a i ʻole ke ahi.No ke kaua ʻana i ke ahi, hoʻohana i ka huʻa waiʻona, ka noe, ka huʻa, CO2, kemika maloʻo.ʻAʻole kūpono me nā mea oxidizing.Ke hoʻomehana ʻia a palaho, hoʻopuka ʻo ia i ka uahi a me ka uahi.
