Intshayelelo
I-Oxymethocoumarin, eyaziwa ngokuba yi-vanillone, i-organic compound.
Umgangatho:
Imbonakalo: I-Oxymethaumarin yikristale emhlophe okanye ephuzi kunye nephunga elikhethekileyo, elifana ne-vanilla.
Ukunyibilika: I-Oxymethocoumarin inyibilika kancinane emanzini ashushu, kodwa phantse ayinyibiliki emanzini abandayo. Iyanyibilika kwii-solvents eziphilayo ezifana ne-ethanol, i-ether kunye ne-chloroform.
Iimpawu zeMichiza: I-Oxymethacoumarin izinzile kwisisombululo esine-asidi, kodwa kulula ukubola kwisisombululo esinamandla se-alkaline okanye ubushushu obuphezulu.
Sebenzisa:
Indlela:
I-Oxymethaumarin inokukhutshwa kwi-vanilla yendalo kwaye isuka kwizityalo ze-vanilla herbaceous ezifana ne-vanilla bean okanye ingca ye-vanilla. Ukongeza, inokulungiswa ngeendlela zokwenziwa, ngokuqhelekileyo isebenzisa i-coumarin yendalo njengento eluhlaza, kwaye iguqulwe ngoluhlu lweekhemikhali.
Ulwazi ngoKhuseleko:
I-Oxymethocoumarin ngokuqhelekileyo ithathwa njengekhuselekile, kodwa ukuguquguquka komzimba kunokwenzeka kwabanye abantu. Xa iveliswa kwaye isetyenziswa kwishishini, amanyathelo afanelekileyo okhuseleko kufuneka athathwe, njengokunxiba iiglavu zokhuselo kunye neendondo zokukhusela. Ukunxibelelana nezinto ezinjengeeasidi ezomeleleyo, iialkali ezinamandla, kunye neeoksijini kufuneka kuphetshwe ukuphepha ingozi.
