Isingeniso

I-1-penten-3-one iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-1-penten-3-one:

 

Ikhwalithi:

I-1-penten-3-one iwuketshezi olungenambala olunephunga elinamandla elifana nelikagrisi. Inokuminyana okukhanyayo nesisindo samangqamuzana esihlobene esingu-84.12 g/mol.

 

Sebenzisa:

I-1-penten-3-one inezinhlobonhlobo zokusetshenziswa. Kuyimpahla ebalulekile yokwenziwa kokuhlanganiswa kwezinto eziningi eziphilayo ekuhlanganiseni kwayo. Ibuye isetshenziswe njengesithako ezinngolweni nasezindaweni zokunambitheka.

 

Indlela:

I-1-Penten-3-one ingalungiswa ngezindlela ezihlukahlukene. Enye yezindlela ezivame ukusetshenziswa itholakala nge-oxidation ye-pentene. Ngemuva kwe-oxidation ye-pentene nge-catalyst, i-1-penten-3-one ingatholakala ngaphansi kwezimo ezifanele zokusabela.

 

Ulwazi Lokuphepha:

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
