Isingeniso

(5h) i-furanone iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali engu-C8H12O3 kanye nesisindo samangqamuzana esingu-156.18g/mol. Iwuketshezi oluphuzi olungenambala ukuya kokuphaphathekile olunoshukela-ushukela okhethekile. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

 

Imvelo:

-Ukubukeka: Uketshezi olungenambala oluphuzi olukhanyayo

-Indawo yokuncibilika: -7 ℃

Iphuzu elibilayo: 171-173 ℃

-Ukuminyana: cishe. 1.079g/cm³

-Ukunyibilika: Kungancibilika emanzini, ethanol nasezincibilikisini ze-Ether

-Ukuzinza: kuzinzile kumazinga okushisa asekamelweni

 

Sebenzisa:

-Isengezo sokudla: Ngenxa yobumnandi baso obukhethekile, sisetshenziswa njenge-agent yokunambitheka kokudla, ikakhulukazi kumaswidi, ujamu kanye ne-dessert.

-Izinongo: Ingasetshenziswa njenge-condiment ukunikeza ukudla ukunambitheka okuyingqayizivele.

-Imboni yamakha: njengenye yezithako ze-perfume essence.

 

Indlela:

(5h) i-furanone ingalungiswa ngezinyathelo ezilandelayo:

1. Nge-3-methyl -2-pentanone njengento yokuqala, i-3-hydroxy -4-methyl -2-pentanone itholwe ukusabela kwe-keto-alcohol.

I-2.3-hydroxy -4-methyl -2-pentanone isabela nge-ejenti ye-etherifying (njenge-diethyl ether) ukuze kukhiqizwe umkhiqizo we-etherification.

3. Umkhiqizo we-etherification ungaphansi kwe-acid catalysis kanye ne-deoxidation reaction ukuze uthole i-furanone (5h).

 

Ulwazi Lokuphepha:

-(5h) i-furanone ibhekwa njengephephile ukusetshenziswa okuvamile, kodwa ingase icasule isikhumba namehlo lapho kugxilwe kakhulu.

-Sebenzisa kufanele banake izinyathelo zokuzivikela, ugweme ukuthintana nesikhumba namehlo, futhi ugcine indawo yokusebenza enomoya omuhle.

-Landela izinqubo zokuphepha ezifanele lapho uyisebenzisa, futhi uyigcine endaweni eyomile, epholile, kude nomlilo nezinto ezikhipha i-oxidizing.

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