Kev siv tetrahydrofuran txhua hnub

1. Siv los ua cov kuab tshuaj thiab cov khoom siv raw rau cov organic synthesis.

2. Siv los ua chromatographic reagent, organic solvent thiab nylon 66 intermediate. Tetrahydrofuran, tseem hu ua monocyclopentadecane, oxyheterocyclopentane thiab tetramethylene oxide, yog ib qho nruab nrab rau kev sib txuas ntawm cov tshuaj tua kab phenylbutyltin. Tsis tas li ntawd, nws tuaj yeem siv ncaj qha los tsim cov khoom siv hluavtaws, hluavtaws resins thiab hluavtaws roj hmab. Nws kuj yog ib qho hnyav rau ntau cov ntaub ntawv polymer, precision tapes thiab electroplating industries. Nws kuj yog siv los tsim adiponitrile, adipic acid, hexamethylene diamine, succinic acid, butanediol - Butyrolactone, thiab lwm yam hauv kev lag luam kws, tuaj yeem siv rau hauv kev tsim cov kebiqing, progesterone, rifamycin thiab ua cov tshuaj hnyav.

3. Tetrahydrofuran yog ib qho tseem ceeb organic hluavtaws raw khoom thiab cov kuab tshuaj nrog kev ua tau zoo heev. Nws yog tshwj xeeb tshaj yog haum rau dissolving PVC, polyvinylidene chloride thiab butylamine. Nws yog dav siv los ua cov kuab tshuaj rau saum npoo txheej, tiv thaiv corrosion txheej, luam ntawv inks, tapes thiab zaj duab xis txheej, thiab ua cov tshuaj tiv thaiv hnyav. Thaum nws yog siv rau electroplating aluminium tov, nws muaj peev xwm arbitrarily tswj lub thickness thiab brightness ntawm txhuas txheej. Tetrahydrofuran nws tus kheej tuaj yeem ua tau polycondensated (ntawm cation pib lub nplhaib qhib repolymerization) rau hauv poly tetramethylene ether glycol (PTMEG), tseem hu ua tetrahydrofuran homopolyether. PTMEG thiab toluene diisocyanate (TDI) ua cov roj hmab tshwj xeeb nrog kev hnav tsis kam, roj ua haujlwm, kev ua haujlwm kub tsis zoo thiab lub zog siab; Thaiv polyether polyester elastic khoom yog tsim nrog dimethyl terephthalate thiab 1, 4-butanediol. PTMEG nrog cov txheeb ze molecular hnyav ntawm 2000 thiab p-methylene bis (4-phenyl) diisocyanate (MDI) yog raw cov ntaub ntawv rau polyurethane elastic fiber (spandex fiber), roj hmab tshwj xeeb thiab ib co coatings tshwj xeeb. Nyob rau hauv cov organic synthesis, nws yog siv los tsim Tetrahydrothiophene, 1.2-dichloroethane, 2.3-dichlorotetrahydrofuran, pentylene lactone, butyrolactone thiab pyrrolidone. Hauv kev lag luam kws tshuaj, THF yog siv los ua kebiqing, rifamycin, progesterone thiab qee cov tshuaj hormones. THF yog kho nrog hydrogen sulfide los tsim tetrahydrothiophenol, uas tuaj yeem siv los ua cov ntxhiab tsw (cov cim qhia ntxiv) hauv roj roj. THF kuj tseem siv tau los ua tus neeg sawv cev kho mob rau cov tawv hluavtaws.
