Intshayelelo

I-3,4-Hexanedione (eyaziwa ngokuba yi-4-Hexanediic Acid) yi-organic compound. Oku kulandelayo sisingeniso esifutshane kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa, kunye nolwazi lokhuseleko:

Umgangatho:

- Imbonakalo: 3,4-Hexanedione yinto eqinileyo yecrystalline engenambala.

- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana namanzi, iialkoholi kunye neetha.

- Iimpawu zeMichiza: I-3,4-hexanedione i-ketone compound kunye ne-reactivity ye-ketone eqhelekileyo. Inokuncitshiswa ibe yi-diol ehambelanayo okanye i-hydroxyketone, kwaye inokuphinda ifumane iimpendulo ezifana ne-esterification kunye ne-acylation.

Sebenzisa:

- Isenokusetyenziswa njengemathiriyeli ekrwada yokwaleka, iiplastiki, kunye nerabha, kunye nendawo ephakathi kwiikhemikhali zokuphinda zisebenze kunye neecatalysts.

Indlela:

- Kukho iindlela ezahlukeneyo zokuhlanganisa i-3,4-hexanedione, enye yeendlela eziqhelekileyo zokulungiselela i-esterify formic acid kunye nepropylene glycol ukufumana i-ester ye-3,4-hexanedione, kwaye emva koko ufumane imveliso yokugqibela nge-acid hydrolysis.

Ulwazi ngoKhuseleko:

- I-3,4-Hexanedione yinto eqhelekileyo yezinto eziphilayo kwaye kufuneka igwenywe ekudibaneni nesikhumba, i-inhalation okanye i-inhalation.

- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi kunye nempahla yokuzikhusela.

- Ngexesha lokugcinwa kunye nokuphatha, ingqwalasela kufuneka ihlawulwe kwimithombo yokutshisa kunye nokudibanisa nezinto ezinokutsha, i-oxidants kunye nezinye izinto kufuneka zigwenywe.

Ngaphambili: I-2-4-Heptadienal (CAS#5910-85-0)

Okulandelayo: 2-Ethoxy-3-Isopropyl Pyrazine (CAS#72797-16-1)
