4'-Ethylpropiophenone (CAS# 27465-51-6)

Mawu Oyamba

4-Ethylpropiophenone ndi organic pawiri ndi mankhwala formula C11H14O. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

Chilengedwe:

-Maonekedwe: 4-Ethylpropiophenone ndi madzi achikasu otumbululuka.

-Kununkhira: Kumakhala ndi fungo lapadera.

- Kachulukidwe: pafupifupi 0.961g/cm³.

- Malo otentha: Pafupifupi 248 ° C.

-Kusungunuka: Kusungunuka mu ethanol, ether ndi Ester solvents, osasungunuka m'madzi.

Gwiritsani ntchito:

-Kugwiritsa ntchito m'mafakitale: 4-Ethylpropiophenone imagwiritsidwa ntchito ngati gawo lapakati pakupanga mankhwala m'mafakitale ena.

-Kaphatikizidwe ka mankhwala: Atha kugwiritsidwa ntchito popanga zinthu zina monga mankhwala, mankhwala ophera tizilombo ndi zonunkhira.

-Zodzoladzola ndi zonunkhira: Chifukwa cha kununkhira kwake, 4-Ethylpropiophenone ingagwiritsidwe ntchito ngati zopangira zodzoladzola ndi zonunkhira.

Njira:

Njira yokonzekera 4-Ethylpropiophenone ikhoza kuchitidwa ndi izi:

1. Sakanizani acetophenone ndi ethyl acetate mu gawo loyenera.

2. Condensation ikuchitika kudzera asidi-catalyzed anachita pansi yoyenera kutentha ndi zinthu.

3. Kupyolera mu kutentha ndi distillation, chandamale pawiri 4-Ethylpropiophenone yotengedwa kusakaniza anachita.

Chonde dziwani kuti muyenera kulabadira otetezeka ntchito pokonzekera ndondomeko, kupewa kukhudzana ndi khungu ndi inhalation wa volatiles, ndi ntchito zipangizo zodzitetezera ndi zinthu mpweya wabwino.

Zambiri Zachitetezo:

4-Ethylpropiophenone ndi mankhwala, ayenera kulabadira zinthu zotsatirazi chitetezo:

-Pewani kukhudza khungu ndi maso. Valani magolovesi oteteza, magalasi ndi zovala zodzitchinjiriza mukamagwira ntchito.

-Pewani kutulutsa mpweya wovunda. Panthawi yogwira ntchito, mpweya wabwino uyenera kutetezedwa.

-Kusunga pamalo owuma, opanda mpweya, kutali ndi moto komanso kutentha kwambiri.

-Pogwiritsa ntchito pawiri, iyenera kugwiritsidwa ntchito molingana ndi bukhu lothandizira komanso malamulo okhudzana ndi chitetezo.
