Mawu Oyamba

5-methyl-2-acetylfran ndi organic pawiri.

 

Chopangacho chili ndi zinthu zotsatirazi:

Maonekedwe: madzi opanda mtundu kapena opepuka achikasu.

Kusungunuka: Kusungunuka muzinthu zambiri zosungunulira, monga Mowa, methanol ndi methylene chloride.

Kachulukidwe: pafupifupi 1.08 g/cm3.

 

Ntchito zazikulu za 5-methyl-2-acetylfran ndi monga:

Kaphatikizidwe ka Chemical: Monga gawo lapakati pazochita za organic synthesis, zitha kugwiritsidwa ntchito kupanga ma organic mankhwala ena.

 

Njira zopangira 5-methyl-2-acetylfran ndi monga:

Amapangidwa kuchokera ku 5-methyl-2-hydroxyfuran ndi acylation.

Amakonzedwa ndi acetylation ya 5-methylfuran ndi acetylating agent (mwachitsanzo, acetic anhydride) ndi chothandizira (mwachitsanzo, sulfuric acid).

 

Zimakwiyitsa ndipo ziyenera kupeŵedwa kuti musagwirizane ndi khungu ndi maso.

Kukoka mpweya kapena kuyamwa mwangozi kungayambitse kupsa mtima kwa m'mapapo ndi kusapeza bwino m'mimba, ndipo ana ndi ziweto ziyenera kusungidwa kutali.

Njira zoyenera zodzitetezera, monga kuvala zovala zoteteza maso ndi magolovesi, ziyenera kugwiritsidwa ntchito panthawi yantchito.

Posungira, iyenera kutsekedwa mwamphamvu komanso kutali ndi magwero amoto ndi okosijeni.
