Tsis ntev los no, 1,4-butanediol (BDO) tau dhau los ua lub ntsiab lus kub hauv cov kab tshuaj. Raws li cov khoom siv tshuaj uas tseem ceeb heev organic tshuaj tiv thaiv kab mob raw, nws tau txhaj rau ntau yam kev lag luam nrog nws cov kev siv ntawm kev tsim khoom loj ntawm lub saw hlau loj heev.
Ntawm cov kab ntau lawm ntawm cov khoom lag luam polyester, 1,4-butanediol qhia tau tus nqi thiab tus nqi heev. Cov synthesis ntawm polybutylene Terephthalate (PBT) cia siab rau nws. PBT, raws li kev ua tau zoo thermoplastic polyester engine, muaj cov tshuaj ua kom zoo nkauj, thiab hluav taws xob rwb thaiv tsev thiab seem ruaj khov. Tam sim no, cov cuab yeej siv hluav taws xob thiab hluav taws xob kev lag luam yog nthuav dav nrawm, nrog ntau cov khoom siv hauv tsev ntse nthuav dav tsis tu ncua. Cov cuab yeej siv hluav taws xob thiab cov txuas ua los ntawm PBT cov ntaub ntawv tsis tsuas yog ua kom muaj kev nyab xeeb thiab tsis ruaj khov thiab ruaj khov, ua rau muaj kev lag luam lag luam zoo nkauj. Lub Automotive kev lag luam kuj tau qhia qhov zoo tshaj plaws nyiam rau PBT. Qhov chaw xws li lub qhov rooj tsheb thauj khoom thiab cov pob khoom ua los ntawm PBT tuaj yeem tiv thaiv cov yaig ntawm txoj kev ntawm txoj kev tsheb ntawm lub tsheb.
Hauv kev ua haujlwm ua haujlwm ntawm thermoplastic polyurethane (TPU), 1,4-Butanediol kuj yog tus tub ntxhais ". TPU ua ke cov roj hmab siab ntawm cov roj hmab nrog cov khoom yooj yim ntawm cov yas, thiab cov tiav cov khoom lag luam yog hnav-resistant, roj-resistant, thiab mob khaub thuas-resistant, thiab txias. Los ntawm cov soles ntawm cov kis las ncaws pob niaj hnub, kev tiv thaiv kev nyab xeeb ntawm cov kab mob kev lag luam, thiab tom qab ntawd rau cov khoom siv kev nyab xeeb, thiab nws yog qhov kev ua haujlwm ntawm kev ua haujlwm sib ntaus, thiab tom qab ntawd rau kev ua haujlwm ntawm kev ua haujlwm sib ntaus sib tua
Cov txheej txheej, number case, thiab luam tawm thiab downing thiab dye kev lag luam kuj tau hloov pauv tshiab tsis ntev los no ua tsaug rau 1,4-butanediol. The γ-Butyrolactone tsim tawm los ntawm nws muaj lub siab npau npau thiab cov khoom siv hluav taws xob yooj yim, thiab cov qauv ua kom yooj yim dua, thiab ntau dua cov khoom siv kom yooj yim dua, thiab ntau dua cov khoom siv ua kom zoo dua qub Ntxiv mus, raws li cov khoom pib rau cov synthesterical qhib kev tshawb fawb thiab kev tsim kho cov khoom lag luam zoo kom tau tsim ntawm kev ua lag luam.
Hauv qab booming yoj ntawm cov roj teeb roj teeb lithium (n-mep), ib qho kev ua haujlwm ntawm 1,4-butanediol, tau nyiam ntau. Raws li polar apotic hnyav, NMP tau kov yeej qhov teeb meem ntawm cov khoom siv hluav taws xob lithium roj teeb hluav taws xob, kom yooj yim ntawm cov khaub ncaws sib xyaw thiab cov khoom siv. Nws yog lub unsung hero tom kev txhim kho ntawm cov kev ua tau zoo thiab kev ua tau zoo lithaium roj teeb, muaj zog txhawb nqa cov khoom lag luam tshiab thiab cov khoom siv hluav taws xob tshiab.
Ntawm cov Frontiers ntawm kev zam thiab textiles, tetrahydrofuran (ptmeg), uas dhau los ua cov khoom siv rawgen rau spandex fibers thiab polyurethane elastomers. Qhov no ua rau muaj kev ua yeeb yam thiab qib siab kawg ua raws li tib neeg lub cev, ua ke ua ke, thiab siv cov ntaub uas tsis muaj peev xwm ua rau muaj kev pom zoo thiab hloov pauv tau.
Nyob rau hauv daim teb ntawm cov kws tshawb tshuaj tshawb nrhiav thiab kev loj hlob, 1,4-butanediol ntsiag to ua raws li "tus hero ntawm" Unsung ". Raws li ib qho tseem ceeb kws tshuaj hauv nruab nrab, nws koom nrog hauv cov tshuaj synthesis ntawm qee cov tshuaj steroid thiab tshuaj tua kab mob. Nws yog zoo li cov tsev muag khoom muag rau kev tsim cov tshuaj molecular, pab cov kws tshawb fawb tau muab cov qauv tshuaj thiab muab cov mos txwv nyuaj rau kev kov yeej cov kab mob nyuaj.
Nrog rau kev txhim kho kev txuas ntxiv ntawm kev ua lag luam xav tau kev lag luam tshiab, nrog kev lag luam tshiab ntxiv, sau cov tshooj tshiab tshaj plaws hauv kev lag luam tshuaj.
