Isingeniso

I-Gamma octinolactone yaziwa nangokuthi i-2-octinolactone. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela, nolwazi lokuphepha lwe-gamma octinolactone:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Ukunyibilika: Kuxubana nezinyibilikisi eziningi eziphilayo

- Ukuvutha: kuwuketshezi oluvuthayo

 

Sebenzisa:

- Ingasetshenziswa futhi njengesithako ekukhoneni, okokuhlanza, namakha okwenziwa.

 

Indlela:

I-Agamagnyllactone ivamise ukulungiselelwa nge-esterification. Indlela yokulungiselela esetshenziswa kakhulu i-esterify caprylic acid (C8H16O2) ne-isopropanol (C3H7OH) ngaphansi kwesenzo se-acid catalyst ukukhiqiza i-gamma octyrolactone.

 

Ulwazi Lokuphepha:

- I-Glutaminolactone iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile namazinga okushisa aphezulu.

- Gcina umoya omuhle lapho usebenzisa i-gamma octinolactone futhi ugweme ukuhogela umhwamuko wayo.

- Ukuchayeka ku-gamma octinolactone kungase kubangele ukucasuka kwamehlo nesikhumba, ngakho gqoka amagilavu ​​okuzivikela kanye nezibuko lapho uphatha inqubo.

- Ngesikhathi sokusetshenziswa nokugcinwa, kufanele kuqashelwe ukugwema ukuthintana nama-oxidants aqinile nama-acids aqinile ukuze kugwenywe ukusabela kwamakhemikhali.

- Izinqubo ezifanele kanye nezinqubo zokusebenza eziphephile kufanele zilandelwe lapho kusingathwa i-gamma octinolactone ukuqinisekisa ukuphepha komuntu siqu nokuvikelwa kwemvelo.

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