Ethylene glycol (tseem hu ua 1, 2-ethanediol, molecular formula HOCH2CH 2OH) yog cov kua tsis muaj xim, oily kua uas muaj qab zib thiab tsw tsw. Nws yog tsim los ntawm ethylene oxide, uas tau los ntawm ethylene.
Y Yuav ua li cas hom tshuaj yog ethylene glycol?
Ethylene glycol, tseem hu ua ethane-1, 2-diol, tus tswv cuab yooj yim ntawm glycol tsev neeg ntawm cov organic tebchaw. Ib glycol yog cawv nrog ob pawg hydroxyl ntawm cov pa roj carbon atoms uas nyob ib sab (a 1, 2-diol). Lub npe ethylene glycol txhais tau tias "glycol muab los ntawm ethylene."

Yuav ua li cas cov organic compound muaj ib pawg hydroxyl functional?
Alcohols yog cov organic tebchaw uas cov pab pawg hydroxyl ua haujlwm (-OH) raug khi rau carbon atom. Cawv yog ib chav kawm tseem ceeb ntawm cov molecules nrog ntau yam kev tshawb fawb, kev kho mob, thiab kev lag luam.
Dab tsi yog pab pawg ua haujlwm ntawm ketone?
In chemistry, a ketone /ˈkiːtoʊn/ is a functional group nrog covqauv R2C=O , qhov twg R tuaj yeem ua ntau yam sib txawv ntawm cov pa roj carbon. Ketones muaj cov pab pawg carbonyl (carbon-oxygen ob daim ntawv cog lus). Qhov yooj yim tshaj plaws ketone yog acetone (R=R'=methyl), nrog rau cov mis CH3C(O)CH3.
