Mawu Oyamba

Ethyl valerate. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha ethyl valerate:

 

Ubwino:

- Maonekedwe: Madzi opanda mtundu

- Fungo: Fungo la mowa wokhala ndi zipatso

- Poyatsira: pafupifupi 35 digiri Celsius

- Kusungunuka: kusungunuka mu ethanol, ethers ndi organic solvents, osasungunuka m'madzi

 

Gwiritsani ntchito:

- Kugwiritsa ntchito mafakitale: Monga chosungunulira, chitha kugwiritsidwa ntchito m'makampani opanga mankhwala monga utoto, inki, zomatira, ndi zina.

 

Njira:

Ethyl valerate ikhoza kukonzedwa ndi esterification ya valeric acid ndi ethanol. Pochita izi, valeric acid ndi ethanol zimawonjezedwa ku botolo la zomwe zimachitika, ndipo zopangira acidic monga sulfuric acid kapena hydrochloric acid zimawonjezedwa kuti zikwaniritse esterification.

 

Zambiri Zachitetezo:

- Ethyl valerate ndi madzi oyaka, choncho ayenera kusungidwa kutali ndi moto ndi kutentha kwambiri, ndikusungidwa pamalo abwino mpweya wabwino.

- Kuwonetsedwa ndi ethyl valerate kumatha kuyambitsa kuyabwa kwamaso ndi khungu, kotero valani magolovesi oteteza komanso chitetezo chamaso mukamagwiritsa ntchito.

- Ngati walowa m'mphuno mwangozi kapena mwangozi, musamutsire wodwalayo ku mpweya wabwino ndikupita kuchipatala mwamsanga ngati matendawa ali ovuta.

- Posunga, sungani chidebecho chotsekedwa mwamphamvu kuti musamakhale ndi okosijeni ndi ma asidi kuti mupewe ngozi.
