Taw qhia

3-isochromanone (3-isochromanone) yog cov organic compound, tseem hu ua 3-isochromonone. Cov hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev tsim thiab kev nyab xeeb cov ntaub ntawv ntawm 3-isochromanone:

 

Xwm:

-Cov tsos mob: 3-isochromanone yog xim tsis muaj xim rau daj ntseg daj.

-Solubility: Nws yog soluble nyob rau hauv ntau yam organic solvents, xws li ethanol, dimethylformamide thiab dichloromethane.

- Melting point: Lub melting point ntawm 3-isochromanone yog hais txog 25-28 ° C.

-Molecular qauv: Nws cov qauv tshuaj yog C9H8O2, nrog rau pawg ketone thiab lub nplhaib benzene.

 

Siv:

-Raws li nruab nrab: 3-isochromanone yog ib qho tseem ceeb nruab nrab ntawm ntau cov organic syntheses thiab tuaj yeem siv los ua ke ntau yam tshuaj, tshuaj tsw qab thiab dyes.

-Kev tshawb fawb tshuaj: Hauv kev tshawb fawb tshuaj, 3-isochromanone tuaj yeem siv los ua kom muaj ntau yam sib txuas thiab koom nrog kev sib txawv ntawm cov organic.

 

Txoj Kev Npaj:

Txoj kev tsim cov 3-isochromanone feem ntau tau txais los ntawm kev muab o-hydroxyisochromone rau lub cev qhuav dej hauv cov kua qaub. Cov tshuaj tiv thaiv lub cev qhuav dej no tuaj yeem siv cov tshuaj tiv thaiv acidic xws li sulfuric acid lossis phosphoric acid.

 

Cov ntaub ntawv kev nyab xeeb:

-Toxicity: Muaj cov ntaub ntawv txwv tsis pub muaj tshuaj lom ntawm 3-isochromanone, tab sis nws feem ntau suav tias yog tshuaj lom tsawg.

-Irritation: 3-isochromanone tuaj yeem ua rau lub qhov muag thiab tawv nqaij ua rau khaus, yog li koj yuav tsum xyuam xim rau kev tiv thaiv thaum siv.

-Storage: 3-isochromanone yuav tsum muab cia rau hauv qhov chaw qhuav, txias, deb ntawm hluav taws thiab oxidizing tus neeg sawv cev.

 

Thov nco ntsoov tias cov ntaub ntawv no yog rau cov ntaub ntawv xov xwm nkaus xwb, thiab kev siv tshwj xeeb thiab tuav ntawm 3-isochromanone yuav tsum raug ntsuas raws li cov kev xav tau tshwj xeeb thiab cov kev cai tswj hwm.
