Nhanganyaya
Dihydrovanillin. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza dihydrovanillin:
Hunhu:
-Kuonekwa: Dihydrovanillin haina ruvara kune yero makristasi.
- Solubility: Soluble mune organic solvents uye zvishoma soluble mumvura.
- Kunhuwa: Iine inovava-inotapira, yakafanana nevanilla kana toast.
Shandisa:
Nzira:
Kugadzirira kwe dihydrovanillin kunowanzo kuwanikwa ne phenolic condensation reaction. Matanho chaiwo anosanganisira kuita kwebenzaldehyde uye acetic anhydride yakagadziriswa nealkali uye kupisa pasi pemamiriro akakodzera kuti ibudise dihydrovanillin.
Zvekuchengetedza
- Dihydrovanillin inowanzoonekwa seyakachengetedzeka musanganiswa, asi inogona kukonzera allergic reaction mune vamwe vanhu.
- Kune yakanyanya kuwanda kwe dihydrovanillin, kusangana neganda kunogona kukonzera kutsamwa. Kuchengetedza kwakakodzera senge magirovhosi, gogi, nezvimwewo, kunofanirwa kupfekwa kana uchibata komboni.
- Panguva yekuchengetedza uye kushandiswa, kusangana neakasimba oxidizing agents kana zvinhu zvinopisa zvinofanirwa kudziviswa kudzivirira tsaona.
