Intangiriro
Dihydrovanillin. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya dihydrovanillin:
Ubwiza:
- Kugaragara: Dihydrovanillin nta bara ifite ibara rya kristu y'umuhondo.
- Gukemura: Gushonga mumashanyarazi kandi bigashonga gato mumazi.
- Impumuro: Ifite impumuro nziza-nziza, isa na vanilla cyangwa toast.
Koresha:
Uburyo:
Gutegura dihydrovanillin bikunze kuboneka na reaction ya fenolike. Intambwe zihariye zirimo reaction ya benzaldehyde na anhydride ya acetike iterwa na alkali no gushyuha mugihe gikwiye kugirango itange dihydrovanillin.
Amakuru yumutekano:
- Dihydrovanillin muri rusange ifatwa nkibintu bifite umutekano ugereranije, ariko birashobora gutera allergie reaction kubantu bamwe.
- Kubwinshi bwa dihydrovanillin, guhura nuruhu bishobora gutera uburakari. Uburyo bukwiye bwo kwirinda nka gants, indorerwamo, nibindi, bigomba kwambarwa mugihe ukoresha uruganda.
- Mugihe cyo kubika no gukoresha, guhura nibintu bikomeye bya okiside cyangwa ibikoresho byaka umuriro bigomba kwirindwa kugirango wirinde impanuka.
