Intshayelelo
Dihydrovanillin. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dihydrovanillin:
Umgangatho:
-Imbonakalo: I-Dihydrovanillin ayinambala ukuya kwiikristale ezityheli.
- Ukunyibilika: Inyibilika kwizinyibilikisi zendalo kwaye zinyibilika kancinane emanzini.
- Ivumba: Inevumba elikrakra-eliswiti, elifana ne-vanilla okanye i-toast.
Sebenzisa:
Indlela:
Ukulungiswa kwe-dihydrovanillin kudla ngokufunyanwa yi-phenolic condensation reaction. Amanyathelo athile abandakanya ukusabela kwe-benzaldehyde kunye ne-acetic anhydride eyenziwe nge-alkali kunye nokufudumala phantsi kweemeko ezifanelekileyo ukuvelisa i-dihydrovanillin.
Ulwazi ngoKhuseleko:
-I-Dihydrovanillin ithathwa njengekhompawundi ekhuselekileyo, kodwa inokubangela ukuphazamiseka kwabanye abantu.
- Kwizinga eliphezulu le-dihydrovanillin, ukudibana nolusu kunokubangela ukucaphuka. Izilumkiso ezifanelekileyo ezinje ngeeglavu, iiglasi, njl. njl., kufuneka zinxitywe xa kusingathwa ikhompawundi.
- Ngexesha lokugcinwa kunye nokusetyenziswa, ukudibanisa kunye ne-oxidizing agents ezinamandla okanye izinto ezinokutsha kufuneka zigwenywe ukuphepha izingozi.
