Nhanganyaya

1-penten-3-one is an organic compound. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye1-penten-3-one:

 

Hunhu:

1-penten-3-one imvura isina ruvara ine kunhuhwirira kwakasimba kwegirisi. Iine huremu hwekureruka hune hama molecular mass ye84.12 g/mol.

 

Shandisa:

1-penten-3-imwe ine zvakasiyana-siyana zvekushandisa. Icho chinhu chakakosha mbishi chekugadzirisa kweakawanda organic komisheni mukuumbwa kwayo. Inoshandiswawo sechinhu chinonhuwira muzvinonhuwira uye zvinonhuwira.

 

Nzira:

1-Penten-3-imwe inogona kugadzirirwa nenzira dzakasiyana-siyana. Imwe yenzira dzinowanzoshandiswa inowanikwa neoxidation yepentene. Mushure meiyo oxidation yepentene neiyo catalyst, 1-penten-3-imwe inogona kuwanikwa pasi pemamiriro ekuita akakodzera.
