1.049-1.05 g / cm³
Qhov ntom ntawm glacial acetic acid (piv txwv li anhydrous acetic acid) nws cov qauv kev sib txawv yog 1.049-1.05 g / cmà (hauv 25℃cov xwm txheej). Cov hauv qab no yog cov ncauj lus qhia ntxaws ntxaws:
1. Cov nqi ntom nqi
Feem ntau cov chaw (xws li Baidu Encyclopedia, kev kawm paub, thiab lwm yam) muab cov ntaub ntawv sim tau muaj tseeb rau 1.049 g / cm³.
Tsuas yog ib tsab xov xwm WeChat hauv cov txiaj ntsig tau hais tias qhov ceev yog 2.04 g / cm³ yog qhov, thiab tus sau tsab cai yog tsawg. Tej zaum nws yuav yog typo lossis chav ua yuam kev thiab yuav tsum tsis quav ntsej.
2. Lwm yam khoom siv lub cev
Melting taw tes: 16.6℃(tom qab solidification, nws tsim khov - zoo li muaju, yog li ntawd glacial acetic acid ").
Hneev taw tes: 117.9 degree.
Solubility: yooj yim soluble hauv dej thiab organic kuab (xws li ethanol, ether).
3. Sau ntawv
Ntom ntom yuav raug cuam tshuam los ntawm qhov kub. Piv txwv li, qee cov ntaub ntawv tau sau tseg raws li 1.050 g / cm³ ntawm 20 degree.
Glacial acetic acid yog corrosive heev thiab khaus thiab yuav tsum khaws cia thiab siv nrog kev ceev faj.
Hauv cov ntsiab lus, qhov ntom ntawm glacial acetic acid yuav tsum ua raws li 1.049-1.05 g / cm³. Lwm qhov kev tsis txaus siab yuav tsum tau ua ke nrog kev txiav txim siab ua haujlwm.
