Cov Lus Qhia Tshwj Xeeb

FURFURAL (C5H4O2)

Yam ntxwv

Furfural yog tsim los ntawm cov khoom siv ua liaj ua teb los ntawm txoj kev siv hydrolysis. Nws yog cov xim tsis muaj kob lossis daj uas muaj kua nrog kua txiv almond. Thaum kis nrog huab cua nws hloov mus rau xim av dub lossis tsaus. Cov txheeb ze ceev yog 1.1589. Boiling taw tes yog 161.7 ℃. Nws yog me ntsis soluble hauv dej thiab soluble hauv dej kub, cawv, ether benzene. Cov tso tes taw ntawm furfural ua tiav 393 ℃ thiab qhov kev txwv tawg yog ntawm 2.1% thiab 19.2%.
