Isingeniso
I-Dihydrovanillin. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dihydrovanillin:
Ikhwalithi:
- Ukubukeka: I-Dihydrovanillin ayinambala kumakristalu aphuzi.
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo futhi kuncibilika kancane emanzini.
- Iphunga: Inephunga elibabayo-elimnandi, elifana ne-vanilla noma ithosi.
Sebenzisa:
Indlela:
Ukulungiswa kwe-dihydrovanillin kuvame ukutholwa ngokusabela kwe-phenolic condensation. Izinyathelo ezithile zibandakanya ukusabela kwe-benzaldehyde kanye ne-acetic anhydride eyenziwe nge-alkali nokushisa ngaphansi kwezimo ezifanele ukukhiqiza i-dihydrovanillin.
Ulwazi Lokuphepha:
- I-Dihydrovanillin ngokuvamile ibhekwa njengenhlanganisela ephephile, kodwa ingase ibangele ukungezwani komzimba kwabanye abantu.
- Ngokugxila okuphezulu kwe-dihydrovanillin, ukuthintana nesikhumba kungabangela ukucasuka. Izinyathelo zokuphepha ezifanele ezifana namagilavu, izibuko, njll., kufanele zigqokwe lapho kusingathwa inhlanganisela.
- Ngesikhathi sokugcina nokusetshenziswa, ukuthintana nama-oxidizing aqinile noma izinto ezivuthayo kufanele kugwenywe ukugwema izingozi.
