Tuam Tshoj Tus Nqi Zoo Tetrahydrofuran CAS: 109-99-9

Chaw tsim tshuaj paus Zoo Nqe Tetrahydrofuran CAS: 109-99-9 Featured duab

piav qhia luv luv:

Tetrahydrofuran (THF) yog cov kua tsis muaj xim, tsis muaj kuab lom nrog cov ntxhiab tsw ntxhiab lossis acetonelike thiab yog miscible hauv dej thiab feem ntau cov kuab tshuaj organic.Tetrahydrofuran (THF) yog cov nplaim hluav taws kub heev thiab tuaj yeem ua rau cov pa roj carbon monoxide thiab carbon dioxide thermally decompose.Ntev cia nyob rau hauv kev sib cuag nrog huab cua thiab nyob rau hauv tsis muaj ib tug antioxidant tej zaum yuav ua rau THF decompose rau tawg peroxides.

Kev siv ntawm Tetrahydrofuran

Tetrahydrofuran yog siv rau hauv kev tsim cov polymers nrog rau kev ua liaj ua teb, tshuaj, thiab khoom siv tshuaj.Kev tsim khoom lag luam feem ntau tshwm sim hauv cov kaw lus kaw lossis hauv kev tswj xyuas engineering uas txwv cov neeg ua haujlwm raug thiab tso tawm rau ib puag ncig.THF kuj tseem siv los ua cov kuab tshuaj (xws li, cov yeeb nkab haum) uas yuav ua rau muaj kev cuam tshuam ntau dua thaum siv hauv qhov chaw kaw tsis muaj qhov cua txaus.Txawm hais tias THF yog ib txwm muaj nyob rau hauv kas fes aroma, floured chickpeas, thiab siav nqaij qaib, natural exposures tsis tau xav tias yuav ua rau muaj teeb meem loj.
Butylene oxide yog siv los ua fumigant thiab inadmixture nrog lwm cov tebchaw.Nws yog siv los stabilize roj nrog rau cov xim thiab sludge tsim.
Tetrahydrofuran yog siv los ua ib qho hnyav forresins, vinyls, thiab siab polymers;raws li Grignardreaction nruab nrab rau organometallic, thiab hlau hydride tshua;Thiab nyob rau hauv lub synthesis ntawm succinic acid thiab butyrolactone.
Solvent rau siab polymers, tshwj xeeb tshaj yog polyvinyl chloride.Raws li cov tshuaj tiv thaiv nruab nrab rau Grignard thiab hlau hydride cov tshuaj tiv thaiv.Nyob rau hauv lub synthesis ntawm butyrolactone, succinic acid, 1,4-butanediol diacetate.Solvent nyob rau hauv cov txheej txheem histological.Tej zaum yuav raug siv raws li Tsoom Fwv Teb Chaws Khoom Noj, Tshuaj & Tshuaj pleev ib ce rau kev tsim cov khoom rau ntim, thauj, lossis khaws cia cov khoom noj yog tias cov seem seem tsis pub tshaj 1.5% ntawm zaj duab xis: Fed.Sau npe.27, 3919 (Lub Plaub Hlis 25, 1962).
Tetrahydrofuran yog siv feem ntau (80%) los ua polytetramethylene ether glycol, lub hauv paus polymer siv feem ntau hauv kev tsim cov elastomeric fibers (xws li, spandex) nrog rau polyurethane thiab polyester elastomers (xws li, tawv tawv, skateboard log).Cov seem (20%) yog siv rau hauv cov ntaub ntawv hnyav (xws li, yeeb nkab cements, adhesives, luam ntawv inks, thiab sib nqus daim kab xev) thiab ua cov tshuaj tiv thaiv hnyav hauv tshuaj thiab tshuaj syntheses.
