Mawu Oyamba

1-penten-3-one ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 1-penten-3-one:

 

Ubwino:

1-penten-3-one ndi madzi opanda mtundu okhala ndi fungo lamphamvu ngati mafuta. Ili ndi kachulukidwe kakang'ono kokhala ndi mamolekyu ochepera 84.12 g/mol.

 

Gwiritsani ntchito:

1-penten-3-one ili ndi ntchito zosiyanasiyana. Ndi zofunika zopangira kwa synthesis ambiri organic mankhwala mu kaphatikizidwe ake. Amagwiritsidwanso ntchito ngati chophatikizira mu zonunkhira ndi zokometsera.

 

Njira:

1-Penten-3-imodzi ikhoza kukonzedwa ndi njira zosiyanasiyana. Imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi oxidation ya pentene. Pambuyo pa makutidwe ndi okosijeni wa pentene ndi chothandizira, 1-penten-3-imodzi imatha kupezeka pansi pamikhalidwe yoyenera.
