Isingeniso
I-Oxymethocoumarin, eyaziwa nangokuthi i-vanillone, iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
Ukubukeka: I-Oxymethaumarin iyi-crystalline eqinile emhlophe noma ephuzi enephunga elikhethekile, elifana ne-vanilla.
Ukunyibilika: I-Oxymethocoumarin incibilika kancane emanzini ashisayo, kodwa cishe ayincibiliki emanzini abandayo. Incibilika kuma-organic solvents njenge-ethanol, i-ether ne-chloroform.
Izici zamakhemikhali: I-Oxymethacoumarin izinzile kusisombululo esine-asidi, kodwa kulula ukubola kusisombululo esiqinile se-alkaline noma izinga lokushisa eliphezulu.
Sebenzisa:
Indlela:
I-Oxymethaumarin ingakhishwa ku-vanilla yemvelo futhi itholakala ikakhulukazi ezitshalweni ze-vanilla herbaceous ezifana nobhontshisi we-vanilla noma utshani be-vanilla. Ngaphezu kwalokho, ingabuye ilungiswe ngezindlela zokwenziwa, imvamisa isebenzisa i-coumarin yemvelo njengempahla eluhlaza, futhi iguqulwe ngochungechunge lokusabela kwamakhemikhali.
Ulwazi Lokuphepha:
I-Oxymethocoumarin ngokuvamile ibhekwa njengephephile, kodwa ukungezwani komzimba kungase kwenzeke kwabanye abantu. Lapho ikhiqizwa futhi isetshenziswa embonini, kufanele kuthathwe izinyathelo ezifanele zokuphepha, njengokugqoka amagilavu okuzivikela nezingilazi zokuzivikela. Ukuthintana nezinto ezifana nama-asidi aqinile, ama-alkali aqinile, nama-oxidants kufanele kugwenywe ukuze kugwenywe ingozi.
