Mawu Oyamba

Cyclopentanone, yomwe imadziwikanso kuti pentanone, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha cyclopentanone:

 

Ubwino:

2. Maonekedwe: madzi owonekera opanda mtundu

3. Kulawa: Kumakhala ndi fungo loipa

5. Kachulukidwe: 0,81 g/mL

6. Kusungunuka: Kusungunuka m'madzi, mowa ndi zosungunulira za organic

 

Gwiritsani ntchito:

1. Kugwiritsa ntchito mafakitale: Cyclopentanone imagwiritsidwa ntchito makamaka ngati zosungunulira ndipo ingagwiritsidwe ntchito popanga zokutira, ma resin, zomatira, etc.

2. Reagent mu zochita za mankhwala: Cyclopentaone angagwiritsidwe ntchito ngati reagent ambiri organic synthesis zimachitikira, monga makutidwe ndi okosijeni zimachitikira, kuchepetsa zimachitikira, ndi synthesis wa carbonyl mankhwala.

 

Njira:

Cyclopentanone nthawi zambiri imakonzedwa ndi kung'ambika kwa butyl acetate:

CH3COC4H9 → CH3COCH2CH2CH2CH3 + C2H5OH

 

Zambiri Zachitetezo:

1. Cyclopentanone imakwiyitsa ndipo iyenera kupeŵedwa pakhungu ndi maso, ndikupewa kutulutsa nthunzi yake.

2. Njira zoyendetsera mpweya wabwino ziyenera kuchitidwa panthawi ya ntchito ndipo zida zodzitetezera monga magolovesi ndi magalasi otetezera ziyenera kuvalidwa.

3. Cyclopentanone ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi malawi otseguka ndi magwero a kutentha kwapamwamba pa malo ozizira, a mpweya wabwino.

4. Ngati mwamwaza mwangozi kapena kutulutsa mpweya wambiri wa cyclopentanone, muyenera kupita kuchipatala mwamsanga. Ngati mukumva zofiira, kuyabwa, kapena kutentha m'maso kapena pakhungu, sukani ndi madzi ambiri ndikufunsani dokotala.
