Huahana Huahana
ʻO ka Ethyl vanillin ka mea hoʻohuihui me ke ʻano (C2H5O)(HO)C6H3CHO. ʻO kēia paʻa kala ʻole he apo benzene me nā pūʻulu hydroxyl, ethoxy, a me formyl ma nā kūlana 4, 3, a me 1.
ʻO Ethyl vanillin kahi mole synthetic, ʻaʻole i loaʻa ma ke ʻano. Hoʻomākaukau ʻia ia ma o nā ʻanuʻu mai ka catechol, e hoʻomaka me ka ethylation e hāʻawi i ka "guethol". Hoʻopili kēia etera me ka waikawa glyoxylic e hāʻawi i ka derivative mandelic acid, a ma o ka oxidation a me ka decarboxylation e hāʻawi ai i ka ethyl vanillin.
Ma ke ʻano he mea ʻono, ʻoi aku ka ikaika o ka ethyl vanillin e like me ka vanillin a hoʻohana ʻia i ka hana kokoleka.
