Hoʻolauna

ʻO 1-penten-3-one he mea hoʻohuihui. Eia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 1-penten-3-one:

 

ʻAno maikaʻi:

ʻO 1-penten-3-one he wai waihoʻoluʻu me ka ʻala ikaika e like me ka momona. Loaʻa iā ia ka māmā māmā me ka nui molekala pili o 84.12 g/mol.

 

E hoʻohana:

Loaʻa i ka 1-penten-3-one nā ʻano hoʻohana like ʻole. He mea koʻikoʻi ia no ka hoʻohuihui ʻana o nā pūhui organik he nui i kāna synthesis. Hoʻohana ʻia ia ma ke ʻano he mea hoʻohui i nā mea ʻala a me nā mea ʻono.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka 1-Penten-3-one e nā ʻano hana like ʻole. ʻO kekahi o nā ʻano hana maʻamau i loaʻa ma ka oxidation o pentene. Ma hope o ka oxidation o ka pentene e ka catalyst, hiki ke loaʻa ka 1-penten-3-one ma lalo o nā kūlana hopena kūpono.
