1,4-butaneddiolcas110-63-4: Mutambi anoverengera mumakemikari indasitiri, anoshanda mune itsva boom yezvinhu zvakasiyana siyana

Nguva pfupi yadarika, 1,4-butaneddiol (bdo) yave musoro unopisa mumunda wemakemikari. Sechinyakare chezvemakemikari chemakemikari, chiri kujekesa hutano hutsva mune akawanda maindasitiri ane huwandu hwayo hwakawanda hwekushandisa, achityaira kusimba kweiyo yakakura maindasitiri yeindasitiri.

Pane mitsara yekugadzira yezvigadzirwa zvePolyester, 1,4-butanedolil inoratidza kukosha kusinga tsanangurike. Iyo synthesis yePolybutylene terephthalate (PBT) inovimba zvakanyanya pairi. PBT, seyakanyanya-performplastic polyster enciredheni yepurasitiki, ine zvakakosha zvekushandisa, zvine simba wemakemikari kurwisa, uye kusimbisa kwemagetsi uye kusimbisa kwemagetsi uye kudzikama. Parizvino, magetsi uye magetsi magetsi ekugadzira indasitiri iri kuwedzera nekukurumidza, nemidziyo yakasiyana-siyana yerudzi uye chaiyo yemagetsi zvishandiso zvinobuda zvichiramba zvichingoenderera mberi. Iyo yemagetsi yekushandisa hurukuro uye inobatanidza yakagadzirwa nePBT zvigadzirwa zvisingaverengere kuchengeteka uye kugadzikana kwemidziyo asi zvakare inopa kutaridzika kwakanaka uye kwakasimba, zvichitungamira kune inodaidzira yemusika. Iyo automotation yekugadzira indasitiri inoratidzawo kufarira kukuru kwePBT. Zvikamu zvakadai sekushanda kwemotokari uye bumpers dzakagadzirwa nePBT inogona kutsungirira kurongeka kwemamiriro akaoma emigwagwa uchivandudza iwo mamiriro ese emota.

Muzvirongwa zvekugadzira zveTermoplastic polyurethane (tpu), 1,4-butaneddiol zvakare zvakare inhengo ye "nhengo". TPU inosanganisa yakakura yekukora kweRabha nekuitwa nyore kwepurasitiki, uye zvigadzirwa zvaro zvapera hazvina kupfekedza, zvinodzivirira mafuta, uye chinotonhora. Kubva pamabhegi ezuva nezuva shangu, ayo anopa rutsigiro rwemberi rwezvemitambo zvekutakura mashandiro ekutakura simba, uye nekumhanya kwemari yekugadzira 1,4-butanedoliol inokwanisika.

Kubata, ink, uye kudhinda uye maindasitiri eDyeing ane zvakare shanduko itsva nguva pfupi yadarika kutenda kusvika 1,4-butaneddiol. Iyo γ-butyrolactone yakabikwa kubva kune yakakwira nzvimbo yekubika uye inokatyamadza yakadzika makomputa, uye kujekesa kwemavara uye kujeka uye kwakanyatsojeka, kukonzeresa kusimudzira kwendasitiri yemakemikari echinyakare. Uyezve, sekutanga zvinhu zvekutanga zvezvinonhuwira uye mishonga yemishonga, γ-butyrolactone yakanyarara ichivhura musuwo mutsvagurudzo, uye inotarisirwa kumisikidza zvigadzirwa zvakanyanyisa kuti vatungamire pamusika.

Pasi peiyo masaisai yeiyo Lithium Battery Indasitiri, N-MetHylpyrrodidone (NMP), zvinobva kune 1,4-butaneddiol, yakakwezva kutarisisa kwakawanda. Semupongwe aprotic solvent, nmm yakunda dambudziko rekushamwaridzana kweiyo Lithium Battery electrode zvinhu, kufambisa iyo yunifomu yekusanganisa uye zvinoshanda. Iyo ndiyo isina kusarudzika gamba kumashure kwekushandiswa kweiyo performance uye mhando yeBlhium mabhatiri, kutsigira zvakanyanya milege mitsva yemaindasitiri senge motokari nyowani uye midziyo yekuchengetedza simba.

Pamapfupi efashoni uye machira, Tetrahydrofuran (Tetrahydrofuran (Tetrahydrouran (Tethydrouran) Izvi zvinoita kuti mitambo yemitambo uye yakakwirira-yekupedzisira fashoni inoenderana nemakirimendi emuviri wemunhu, kusanganisa nyaradzo uye pfungwa yekufashama, uye machira ane hushoma hwekuwedzera uye kushanduka.

Mumunda wekutsvagisa kwechechi uye kukura, 1,4-butandediol chinyararire sezvinoita "gamba risina kusarudzika". Seyakakosha pabviro yepakati yepakati, inotora chikamu mune yakaoma synthesis matanho emamwe mishonga inodhaka uye mishonga inorwisa mabhakitiriya. Zvakafanana nezvigadzirwa zvekuvaka zvivakwa zvekugadzira anonyora denda, achibatsira vaongorori vakaraswa zvakanyanyisa zvinodhaka zvinodhaka uye kupa mishonga yezvirwere zvinokunda.

Nekunatsiridza kuenderera kwehunyanzvi uye nekudzika kwekutsvaga kwemusika, iyo indasitiri yechi 1,4 -,4 yebutaniko inotarisirwa kupfuurira, nekukwira muminda inobuda, ichinyora chitsauko chitsva, ichinyora chitsauko chitsva chitsva muindasitiri yemakemikari.
