Patente de Invenção: "DERIVADOS DE OXIMA DO áCIDO CARBOXìLICO". Derivados de oxima do ácido carboxílico que possuem a fórmula I, em que n é 1 ou 0, X representa O ou N, R² e R³ representam quaisquer resíduos de uma R²R³C=NOH oxima e R¹ representa um radical alquila-, alquenila-, alquinila-, cicloalquila-, cicloalquenila-, alcoxialquila-, ariloxiaril-, alcoxiaril-, ariloxialquil- ou aromático substituído ou não-substituído, ramificado ou não-ramificado preferencialmente com 1 até 30 átomos de C, ou X~ n~R¹ representa são úteis como precursores para a liberação de compostos organolépticos, especialmente para aromas, fragrâncias e agentes de mascaração e/ou compostos antimicrobianos. The present invention is an oxime carboxylic acid derivative having the formula I:wherein n is 1 or 0, X is O, R2 and R3 being part of an oxime R2R3C=NOH are individually, substituted or unsubstituted, branched or unbranched alkyl-, alkenyl-, akinyl-, cycloalkyl-, cycloalkenyl-, or aromatic radical and contain less than 30 carbon atoms, and R1 is a substituted or unsubstituted, branched or unbranched alkyl-, alkenyl-, akinyl-, cycloalkyl-, cycloalkenyl-, alkoxyalkyl-, aryloxyaryl-, alkoxyaryl-, aryloxyalkyl-, or aromatic radical, or XnR1 iswhich are useful as precursors for the delivery of organoleptic compounds, especially for flavors, fragrances and masking agents, and/or antimicrobial compounds.
