Mawu Oyamba
Dihydrovanillin. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dihydrovanillin:
Ubwino:
- Maonekedwe: Dihydrovanillin ndi yopanda utoto mpaka makhiristo achikasu.
- Kusungunuka: Kusungunuka mu zosungunulira za organic komanso kusungunuka pang'ono m'madzi.
- Fungo: Lili ndi fungo lonunkhira bwino, lofanana ndi vanila kapena toast.
Gwiritsani ntchito:
Njira:
Kukonzekera kwa dihydrovanillin nthawi zambiri kumapezeka ndi phenolic condensation reaction. Njira zenizeni zimaphatikizapo zomwe benzaldehyde ndi acetic anhydride yopangidwa ndi alkali ndi kutentha pansi pamikhalidwe yoyenera kupanga dihydrovanillin.
Zambiri Zachitetezo:
- Dihydrovanillin nthawi zambiri imadziwika kuti ndi yotetezeka, koma imatha kuyambitsa ziwengo mwa anthu ena.
- Pazinthu zambiri za dihydrovanillin, kukhudzana ndi khungu kungayambitse mkwiyo. Njira zodzitetezera zoyenera monga magolovesi, magalasi, ndi zina zotero, ziyenera kuvala pogwira ntchito.
- Pakusungirako ndikugwiritsa ntchito, kukhudzana ndi oxidizing amphamvu kapena zinthu zoyaka moto ziyenera kupewedwa kupewa ngozi.
