Isingeniso

I-3,4-Hexanedione (eyaziwa nangokuthi i-4-Hexanediic Acid) iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane sezakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza, nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: 3,4-Hexanedione iyi-crystalline solid solid.

- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezifana namanzi, utshwala nama-ether.

- Izakhiwo zamakhemikhali: I-3,4-hexanedione iyinhlanganisela ye-ketone ene-reactivity evamile ye-ketone. Ingancishiswa ibe yi-diol ehambisanayo noma i-hydroxyketone, futhi ingabhekana nokusabela okufana ne-esterification ne-acylation.

 

Sebenzisa:

- Ingasetshenziswa futhi njengezinto ezingavuthiwe zokumboza, amapulasitiki, nerabha, kanye njengendawo ephakathi yama-reagents amakhemikhali kanye nama-catalysts.

 

Indlela:

- Kunezindlela ezihlukahlukene zokuhlanganisa ze-3,4-hexanedione, enye yezindlela ezivamile zokulungiselela i-esterify formic acid ne-propylene glycol ukuze uthole i-ester ye-3,4-hexanedione, bese uthola umkhiqizo wokugcina nge-acid hydrolysis.

 

Ulwazi Lokuphepha:

- I-3,4-Hexanedione iyinhlanganisela evamile yezinto eziphilayo futhi kufanele igwenywe ukuthintana nesikhumba, ukuhogela noma ukungeniswa.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela.

- Ngesikhathi sokugcina nokuphatha, kufanele kuqashelwe imithombo yokuthungela futhi ukuthintana nezinto ezivuthayo, ama-oxidants nezinye izinto kufanele kugwenywe.
