Ethyl Vanillin
I-Ethyl vanillin yi-organic compound kunye ne-formula (C2H5O) (HO) C6H3CHO.Esi siqina esingenambala sineringi yebenzene ene-hydroxyl, ethoxy, kunye namaqela e-formyl ku-4, 3, kunye no-1 kwiindawo ngokulandelelanayo.
I-Ethyl vanillin yi-molecule yokwenziwa, ayifumaneki kwindalo.Ilungiswa ngeendlela ezininzi ukusuka kwicatechol, iqala nge-ethylation ukunika "guethol".Le ether ijiya nge-glyoxylic acid ukunika i-mandelic acid derivative ehambelanayo, ethi nge-oxidation kunye ne-decarboxylation inike i-ethyl vanillin.
Njengencasa, i-ethyl vanillin inamandla aphindwe kathathu njenge-vanillin kwaye isetyenziselwa ukuveliswa kwetshokolethi.
