Dab tsi yog Kev Siv Tseem Ceeb Ntawm Tetrahydrofuran?

Tetrahydrofuran tuaj yeem siv los ua cov kuab tshuaj thiab cov khoom siv raw rau cov organic synthesis. Nws yog siv los ua cov kuab tshuaj aprotic nrog nruab nrab polarity hauv tshuaj tiv thaiv thiab rho tawm. Tetrahydrofuran yog cov kua tsis muaj xim, tsis muaj viscosity nrog cov ntxhiab tsw zoo li ether. Nyob rau hauv chav tsev kub, tetrahydrofuran thiab dej tuaj yeem ua rau qee qhov tsis zoo, thiab qee cov tub lag luam reagent tsis raug cai siv qhov no kom tau txais txiaj ntsig loj ntawm tetrahydrofuran reagent tov nrog dej. Tetrahydrofuran yooj yim los ua peroxide thaum khaws cia. Yog li ntawd, kev lag luam tetrahydrofuran feem ntau siv BHT, uas yog 2, 6-di-tert-butyl-p-cresol, los tiv thaiv oxidation. Tetrahydrofuran tuaj yeem khaws cia rau hauv qhov chaw tsaus hauv lub raj mis kaw nrog sodium hydroxide.

Tetrahydrofuran yog ib qho tseem ceeb ntawm cov organic chemical thiab zoo tshuaj raw khoom, uas yog dav siv nyob rau hauv resin solvents (kab kab xev, PVC nto txheej, ntxuav PVC reactor, tshem tawm PVC zaj duab xis, cellophane txheej, yas luam ntawv number case, thermoplastic polyurethane txheej); Cov tshuaj tiv thaiv kab mob (hom reagents, alkyl alkali hlau tebchaw thiab aryl alkali hlau tebchaw, aluminium hydride thiab boron hydride, steroids thiab macromolecular organic polymers); Chemical intermediates (PTMEG thiab natural gas flavoring agent generated by polymerization); Chromatographic hnyav (gel permeation chromatography). Tetrahydrofuran muaj cov yam ntxwv ntawm cov tshuaj toxicity tsawg, qis boiling point thiab zoo fluidity.
