Taw qhia
Cyclopentanone, tseem hu ua pentanone, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm cyclopentanone:
Zoo:
2. Cov tsos mob: tsis muaj xim tsis muaj pob tshab kua
3. Saj: Nws muaj ib tug pungent tsw
5. Ceev: 0.81 g / mL
6. Solubility: Soluble hauv dej, cawv thiab cov organic solvents
Siv:
1. Muaj kev siv: Cyclopentanone feem ntau yog siv los ua cov kuab tshuaj thiab tuaj yeem siv rau hauv kev tsim cov coatings, resins, adhesives, thiab lwm yam.
2. Reagent hauv tshuaj lom neeg cov tshuaj tiv thaiv: Cyclopentanone tuaj yeem siv los ua reagent rau ntau cov organic synthesis cov tshuaj tiv thaiv, xws li oxidation cov tshuaj tiv thaiv, txo cov tshuaj tiv thaiv, thiab cov synthesis ntawm carbonyl compounds.
Txoj kev:
Cyclopentanone feem ntau yog npaj los ntawm cleavage ntawm butyl acetate:
CH3COC4H9 → CH3COCH2CH2CH2CH3 + C2H5OH
Cov ntaub ntawv kev nyab xeeb:
1. Cyclopentanone ua rau khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus nws cov vapors.
2. Yuav tsum ntsuas qhov cua kom zoo thaum lub sijhawm ua haujlwm thiab cov khoom siv tiv thaiv tus kheej xws li hnab looj tes thiab tsom iav kev nyab xeeb yuav tsum hnav.
3. Cyclopentanone yog cov kua hluav taws kub thiab yuav tsum tau muab cia kom deb ntawm cov nplaim taws thiab qhov chaw kub kub hauv qhov chaw txias, qhov cua zoo.
4. Yog hais tias koj tsis nco qab noj los yog nqus tau ntau ntawm cyclopentanone, koj yuav tsum nrhiav kev kho mob tam sim ntawd. Yog tias koj muaj qhov liab, khaus, lossis kub hnyiab hauv koj lub qhov muag lossis tawv nqaij, yaug nrog dej kom ntau thiab ntsib kws kho mob.
