Dab tsi yog kev kawm qib Tetrahydrofofuran hnyav? 109-99-9?

Tus lej Tetrahydrofuran yog 109-99-9}}, nrog molecular mis ntawm c₄h₈o. Nws yog ib qho tsis muaj kob, pob tshab, cov kua hluav taws xob nrog ether-zoo li tsw. Nws zwm rau tsib-koom nrog Cyclic Ethaws cov tebchaw, yog miscibible nrog ntau ethanol thiab acetone, thiab yog ib qho tseem ceeb tsis muaj protonic polar kuab tshuaj.
Qhov ntsuas kub ntawm Tetranthaduran yog 66 degree, lub ntsej muag melting yog}}}. 8}}} degree (kaw khob). Nws yog yooj yim oxidized los ua peroxides thaum khaws cia hauv huab cua ntev, thiab stabilizers (xws li BHT) yuav tsum tau ntxiv kom muaj kev nyab xeeb.
