I-BDO, iyikhemikhali ephilayo eyisisekelo kanye nezinto ezingavuthiwe zamakhemikhali amahle, ezithuthukiswe ezansi nomfula, futhi zingasetshenziswa ukukhiqiza izinhlobo ezingaphezu kuka-200 zemikhiqizo emihle yamakhemikhali.
I-BDO, Iyingxenye ebalulekile yamakhemikhali aphilayo kanye nezinto ezingavuthiwe zamakhemikhali amahle, ezithuthukiswe ezansi nomfula, futhi zingasetshenziswa ukukhiqiza izinhlobo ezingaphezu kuka-200 zemikhiqizo yamakhemikhali emihle, ehilela imikhakha eminingi, njengokukhiqiza izimoto, izinto zikagesi nezikagesi, ukuxhumana ngolwazi, amapulasitiki obunjiniyela, izinto zokwakha, imishini, i-petrochemical, indwangu, imithi, ukuphrinta, izimonyo nokunye.
Izakhiwo zomzimba
I-1,4-Butanediol iwuketshezi olunamafutha angenambala nendawo encibilikayo engu-20.1°C. Iphoyinti lokubilisa 235 ℃. Iphoyinti elikhanyayo (inkomishi evulekile) 121℃. Ukuminyana okuhlobene d 4201.0171. inkomba ye-refractive nD201.4461. i-viscosity (25℃) 71.5mPa-s. i-hygroscopic. Ihlangana namanzi, inyibilika ku-methanol, i-ethanol, i-acetone, inyibilika kancane ku-ether.
Izakhi ze-Chemical
Ngokusebenza kabusha okuqinile, ingakwazi ukwenza i-oxidation, ukuphelelwa amandla kwamanzi, ukushintshwa, i-polymerization, i-amination, i-esterification, i-halogenation nokunye ukusabela kwamakhemikhali ukukhiqiza uchungechunge lwemikhiqizo yamakhemikhali ebalulekile. I-Ketone, inyibilika kancane ku-ether.
Inqubo yokukhiqiza
Kwenziwe nge-acetylene ne-formaldehyde phambi kwe-catalyst yokwenza i-1,4-butynediol, bese kuba yi-catalytic hydrogenation. Kungenziwa futhi kusuka ku-1,3-butadiene nge-acetic acid ne-oxygen nge-acetyl oxidation, i-hydrogenation, i-hydrolysis nokunye ukusabela.
Ukupakisha nokugcina kanye nezinto zokuhamba
Ipakishwe nge-aluminium, emiphongolweni yensimbi noma emiphongolweni yepulasitiki, noma igcinwe futhi ihanjiswe ngamaloli athwala amathangi njengempahla evuthayo nobuthi. Ngenxa yokuthi indawo yokuncibilika iphezulu njengo-20℃, ithangi kufanele lifakwe ishubhu lokufudumeza.
Sebenzisa
I-1,4-Butanediol isetshenziswa kabanzi ekukhiqizeni i-polybutylene terephthalate (PBT), i-tetrahydrofuran (THF), i-gamma-butyrolactone (GBL), i-N-methyl-pyrrolidone (NMP), i-N-vinylpyrrolidone (NVP), i-polyurethane resin (PU). ) kanye ne-elastic fiber esebenza kahle kakhulu engu-SPANDEX (spandex), namanye amakhemikhali amahle anevelu ephezulu. Isetshenziswa kabanzi njengama-solvents, imithi kanye nezimonyo, ama-plasticizers, ama-ejenti elaphayo, izibulala-zinambuzane, izibulala-zinambuzane, amagwebu esikhumba, imicu, amapulasitiki obunjiniyela, njll.
