Ethyl Vanillin | 121-32-4
Tuairisgeul air bathar
Is e ethyl vanillin an todhar organach leis an fhoirmle (C2H5O)(HO)C6H3CHO. Tha an stuth gun dath seo air a dhèanamh suas de fhàinne benzene le buidhnean hydroxyl, ethoxy, agus formyl air na dreuchdan 4, 3, agus 1, fa leth.
Is e moileciuil synthetigeach a th’ ann an ethyl vanillin, nach lorgar ann an nàdar. Tha e air ullachadh tro ghrunn cheumannan bhon catechol, a 'tòiseachadh le ethylation gus "guethol" a thoirt seachad. Bidh an ether seo a’ dlùthachadh le searbhag glyoxylic gus an derivative searbhag mandelic co-fhreagarrach a thoirt seachad, a bheir tro oxidation agus decarboxylation ethyl vanillin.
Mar bhlasadair, tha ethyl vanillin timcheall air trì tursan cho làidir ri vanillin agus tha e air a chleachdadh ann a bhith a’ dèanamh seoclaid.
