Ethyl Vanillin | 121-32-4
Incazelo Yemikhiqizo
I-Ethyl vanillin iyinhlanganisela yemvelo enefomula (C2H5O)(HO)C6H3CHO. Lesi sici esiqinile esingenambala siqukethe iringi ye-benzene ene-hydroxyl, i-ethoxy, namaqembu e-formyl endaweni engu-4, 3, kanye no-1, ngokulandelanayo.
I-Ethyl vanillin iyi-molecule yokwenziwa, ayitholakali emvelweni. Ilungiswa ngezinyathelo ezimbalwa ukusuka ku-catechol, iqala nge-ethylation ukunikeza "guethol". Le ether ihlangana ne-glyoxylic acid ukuze inikeze okuphumayo kwe-mandelic acid ehambisanayo, okuthi nge-oxidation ne-decarboxylation inikeze i-ethyl vanillin.
Njengesithako esimnandi, i-ethyl vanillin inamandla aphindwe kathathu kune-vanillin futhi isetshenziswa ekukhiqizeni ushokoledi.
