Mawu Oyamba

3,4-Hexanedione (yomwe imadziwikanso kuti 4-Hexanediic Acid) ndi organic compound. Zotsatirazi ndizofotokozera mwachidule za katundu wake, ntchito, njira zopangira, ndi chidziwitso cha chitetezo:

 

Ubwino:

- Maonekedwe: 3,4-Hexanedione ndi kristalo wopanda mtundu wolimba.

- Kusungunuka: Kusungunuka mu zosungunulira organic monga madzi, ma alcohols ndi ethers.

- Chemical katundu: 3,4-hexanedione ndi ketone pawiri ndi mmene ketone reactivity. Itha kuchepetsedwa kukhala diol yofananira kapena hydroxyketone, komanso imatha kukumana ndi zochitika monga esterification ndi acylation.

 

Gwiritsani ntchito:

- Itha kugwiritsidwanso ntchito ngati zopangira zokutira, mapulasitiki, mphira, komanso ngati wapakatikati wamankhwala opangira mankhwala ndi zopangira.

 

Njira:

- Pali njira zosiyanasiyana kaphatikizidwe wa 3,4-hexanedione, imodzi mwa njira wamba kukonzekera ndi esterify asidi formic ndi propylene glycol kupeza ester wa 3,4-hexanedione, ndiyeno kupeza chomaliza mankhwala ndi asidi hydrolysis.

 

Zambiri Zachitetezo:

- 3,4-Hexanedione ndi wamba organic pawiri ndipo ayenera kupewa kukhudzana ndi khungu, inhalation kapena kuyamwa.

- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera.

- Pakusungirako ndikusamalira, chidwi chiyenera kuperekedwa ku magwero oyatsira ndikukhudzana ndi zoyaka, ma okosijeni ndi zinthu zina ziyenera kupewedwa.
