Nhanganyaya

3,4-Hexanedione (inozivikanwawo se4-Hexanediic Acid) inosanganiswa nehupenyu. Iyi inotevera sumo pfupi yezvivakwa zvayo, kushandiswa, nzira dzekugadzira, uye ruzivo rwekuchengetedza:

 

Hunhu:

- Kuonekwa: 3,4-Hexanedione ikristaro isina ruvara yakasimba.

- Solubility: Inonyungudika mune organic solvents senge mvura, doro uye ethers.

- Kemikari zvivakwa: 3,4-hexanedione isanganiswa yeketone ine yakajairika ketone reactivity. Inogona kudzikiswa kune inoenderana diol kana hydroxyketone, uye inogona zvakare kusangana nemabatiro akadai se esterification uye acylation.

 

Shandisa:

-Inogona zvakare kushandiswa seyakagadzirwa zvinhu zvekupfeka, mapurasitiki, uye rabha, pamwe chete seyepakati yemakemikari reagents uye catalysts.

 

Nzira:

- Kune nzira dzakasiyana-siyana dzekugadzira 3,4-hexanedione, imwe yenzira dzakajairika dzekugadzirira ndeye esterify formic acid uye propylene glycol kuwana ester ye3,4-hexanedione, uye wozowana chigadzirwa chekupedzisira ne acid hydrolysis.

 

Zvekuchengetedza

- 3,4-Hexanedione izere organic compound uye inofanira kudzivirirwa kubva pakusangana neganda, inhalation kana kupinza.

- Pfeka midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi uye zvipfeko zvekudzivirira.

- Panguva yekuchengetedza nekubata, kutarisisa kunofanirwa kubhadharwa kune zvitubu zvemoto uye kusangana nezvinopisa, oxidants uye zvimwe zvinhu zvinofanirwa kudzivirirwa.
