Maphunziro a in vitro Vanillylacetone ndi ofanana mu kapangidwe ka mankhwala ndi mankhwala ena onunkhira monga vanillin ndi eugenol. Amagwiritsidwa ntchito ngati chowonjezera chokometsera mu mafuta a sesame ndi zonunkhira kuti awonetse kukoma kwa zonunkhira. Ginger alibe vanillylacetone; Ginger amasinthidwa kukhala gingerol pophika, chomwe ndi chitsanzo chapano cha kusinthidwa kukhala vanillylacetone ndi aldol condensation reaction. Vanillylacetone ikhoza kukhala yogwira ntchito ya ginger kuti ikhale ndi mphamvu yoletsa kutsekula m'mimba.

Mawu Oyamba

4-4-Hydroxy-3-methoxybutyl-2-one, yomwe imadziwikanso kuti 4-hydroxy-3-methoxypentanone, ndi mankhwala achilengedwe. Zotsatirazi ndikuyambitsa zina mwazinthu zake, ntchito, njira zopangira ndi chidziwitso chachitetezo:

 

Ubwino:

- Mawonekedwe: Madzi opanda mtundu kapena opepuka achikasu kapena olimba.

- Kusungunuka: Kusungunuka mu zosungunulira organic monga ethanol ndi dimethylformamide, osasungunuka m'madzi.

- Poizoni: Pawiriyi ndi yapoizoni ndipo imafuna njira zodzitetezera pokoka mpweya kapena kukhudzana ndi khungu.

 

Gwiritsani ntchito:

- Kuyesa kwa Chemistry: Itha kugwiritsidwanso ntchito ngati chothandizira pazoyeserera zina zama chemistry.

 

Njira:

Njira yokonzekera 4-4-hydroxy-3-methoxybutyl-2-imodzi ikhoza kutheka ndi kaphatikizidwe ka organic pamikhalidwe yoyenera. Pakhoza kukhala njira zingapo zokonzekera, koma iyi ndi imodzi mwa njira zomwe zingatheke:

Sungunulani mlingo woyenera wa pentaone mu zosungunulira organic.

Onjezani owonjezera sodium hydroxide solution.

Pa kutentha kosalekeza ndi kupanikizika, methanol imawonjezedwa pang'onopang'ono muzitsulo zomwe zimasakanikirana.

Ndi kuwonjezera kwa methanol, 4-4-hydroxy-3-methoxybutyl-2-imodzi amapangidwa mu anachita osakaniza.

Mankhwalawa amakonzedwanso ndikuyeretsedwa kuti apeze komaliza komaliza.

 

Zambiri Zachitetezo:

- Mankhwalawa ndi oopsa ndipo ayenera kupewa pokoka mpweya kapena kukhudza khungu.

- Njira zodzitetezera ziyenera kutsatiridwa zikagwiritsidwa ntchito, monga kuvala magalasi amagetsi, kuvala magolovesi amankhwala ndi zovala zodzitetezera.

- Kutaya zinyalala: Zinyalala zimasakanizidwa ndi zosungunulira zoyenera ndikutayidwa ndi malo otayira zinyalala oyenerera malinga ndi malamulo amderalo.
