Selelekela
Dihydrovanillin. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea dihydrovanillin:
Boleng:
- Ponahalo: Dihydrovanillin ha e na 'mala ho likristale tse mosehla.
- Solubility: E qhibiliha ka har'a lihlapolli tsa tlhaho 'me e qhibiliha hanyane ka metsing.
- Monko: E na le monko o monate o babang, o ts'oanang le vanila kapa toast.
Sebelisa:
Mokhoa:
Ho lokisoa ha dihydrovanillin hangata ho fumanoa ka phenolic condensation reaction. Mehato e tobileng e kenyelletsa karabelo ea benzaldehyde le acetic anhydride e entsoeng ke alkali le ho futhumatsa tlas'a maemo a loketseng ho hlahisa dihydrovanillin.
Lintlha tsa Tšireletseho:
- Dihydrovanillin ka kakaretso e nkuoa e le motsoako o batlang o bolokehile, empa o ka baka litlamorao ho batho ba bang.
- Bakeng sa likhakanyo tse phahameng tsa dihydrovanillin, ho kopana le letlalo ho ka baka ho teneha. Litlhokomelo tse nepahetseng tse kang liatlana, likhalase, joalo-joalo, li lokela ho apesoa ha u sebetsana le motsoako.
- Nakong ea polokelo le tšebeliso, ho kopana le li-oxidizing tse matla kapa lisebelisoa tse tukang li lokela ho qojoa ho qoba likotsi.
