● Hygroscopicity: BDO muaj qee qib ntawm hygroscopicity. Nyob rau hauv ib puag ncig huab cua, nws yuav nqus noo noo los ntawm huab cua, uas yuav tsum tau txiav txim siab thaum lub sijhawm cia thiab siv kom tsis txhob cuam tshuam cov khoom zoo.

● Kev lag luam chemical synthesis: BDO yog cov khoom uas tseem ceeb heev rau kev tsim cov tshuaj lom neeg. Nws yog tsuas yog siv los tsim - butyrolactone (GBL), TetrahyDrofuran (Thf), thiab Polybutylene Terephthalate (PBT). Los ntawm lub cev qhuav dej, BDO tuaj yeem hloov mus rau hauv THF, uas yog siv dav hauv kev tsim cov noob polymers thiab raws li cov kuab tshuaj. Oxidation ntawm BDO tuaj yeem tsim cov gbl, uas yog ntxiv siv nyob rau hauv synthesis ntawm n}} metyl {} pyrrolidone (nmp) thiab lwm cov khoom lag luam tshuaj tseem ceeb. Cov hws ntawm BDO nrog Terephthalic acid tuaj yeem yuv PBT, qhov siab {}}} Kev ua lag luam engineering yas.

{{{0} ion roj teeb roj teeb: Hauv cov lithium {{0} ion roj teeb, bdo yog siv rau hauv cov electrolytes. Nws tuaj yeem zom cov ntsev lithium thiab lwm yam, thiab tshuaj lom neeg muaj kev ruaj khov pab txhawm rau txhim kho cov kev ua tau zoo thiab kev nyab xeeb ntawm lithium {2} ion roj teeb.

● Polyurethane kev lag luam: B. Ua cov saw txuas txuas ntxiv hauv kev tsim cov polyurethane elastomers, ua npuas ncauj, thiab txheej. Los ntawm reacting nrog Diisocyanates, nws pab ua kom muaj qhov ntev}}}} Cov khoom lag luam polyurethan, xws li lub zog zoo, thiab elasticity. Cov khoom no tau siv dav hauv cov khoom lag luam, cov khoom siv tsim kho, khau khau, thiab rooj tog zaum.

Pro TextLile Thiab Yas Kev Lag Luam: Hauv kev lag luam textile, BDO {{{0} Cov khoom lag luam tuaj yeem siv ua cov khoom siv ua tiav los txhim kho cov kev xav thiab kev ua haujlwm ntawm cov ntaub. Hauv kev lag luam yas, qee cov derivatives ntawm BDO tau siv los ua kom yooj yim thiab muaj txiaj ntsig ntawm cov khoom yas xws li PVC cov khoom lag luam.

● Cov tshuaj pleev ib ce thiab cov kws tshuaj: Vim tias nws zoo solubility thiab kuj muaj kev lom zem, BDO tuaj yeem siv los ua cov kuab tshuaj thiab kev ua kom pom cov tshuaj pleev ib ce, pab kom yaj cov khoom xyaw. Hauv kev lag luam kws tshuaj, nws kuj tseem siv tau los ua cov tshuaj los yog nruab nrab hauv kev sib xyaw ntawm cov tshuaj.

● Nyob rau hauv tshuaj lom neeg synthesis: Thaum siv BDO hauv tshuaj lom neeg cov tshuaj tiv thaiv, tswj hwm raug cov tshuaj tiv thaiv muaj tseeb xws li lub sijhawm kub, thiab cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv raws li cov tshuaj tiv thaiv. Xyuas kom meej tias cov tshuaj tiv thaiv kev siv tshuaj tiv thaiv huv thiab qhuav kom tsis txhob muaj kev cuam tshuam tsis zoo ntawm cov tshuaj tsis zoo thiab noo noo ntawm cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv, tau sib cais ua kom haum thiab txoj kev ua kom huv si kom tau txais siab- cov khoom lag luam zoo thiab rov qab siv BDO.

● Hauv lithium {{0} ion roj teeb electrolyte npaj: Thaum npaj cov electrolytes, nruj me ntsis tswj cov feem ntawm BDO thiab lwm yam. Nco ntsoov tias cov ntaub ntawv raw yog cov kev ua kom tiav kom tsis txhob cuam tshuam rau kev ua tau zoo ntawm electrolyte. Them sai sai rau cov ntsiab lus ya raws hauv cov kab ke, raws li noo noo tuaj yeem hnov ​​mob thiab cuam tshuam rau lub roj teeb kev ua tau zoo.

● Hauv polyurethane ntau lawm: Raug ntsuas ntsuas qhov ntau npaum li cas ntawm BDO thiab lwm cov ntaub ntawv raw raws li kev tsim qauv. Xyuas kom meej kev sib xyaw ua ke ntawm txhua cov khoom sib xyaw ua kom ua tiav cov kev sib txawv.
