Khoom siv

Grignard Reagent THF nws tus kheej tuaj yeem ua tau polycondensed (los ntawm cation-initiated nplhaib-qhib repolymerization) los ua polytetramethylene 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; ua thaiv polyether polyester elastic nrog dimethyl terephthalate thiab 1, 4-butanediol Khoom. PTMEG nrog cov txheeb ze molecular loj ntawm 2000 thiab p-methylene bis (4- phenyl) diisocyanate (MDI) yog siv los ua raw khoom rau polyurethane elastic fibers (spandex, uas yog SPANDEX fibers), roj hmab tshwj xeeb thiab ib co coatings tshwj xeeb. . Nyob rau hauv cov organic synthesis, nws yog siv los tsim tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, valerolactone, butyrolactone thiab pyrrolidone.
