摘要：The aromatic components in citrus essential oils are monoterpenes, sesquiterpenes, and some oxygenated compounds. It is known that monoterpenes, such as limonene, take a little part of the aroma and are sometimes removed by deterpenation processes. In this study, a novel technology through a wet oxidation process using hydrogen peroxide was investigated for the conversion of limonene. Experiments were conducted using a batch type reactor to study the effects of temperature and reaction time on the conversion of limonene under the following conditions: temperature range of 150 to 200C at reaction time of 10-80 min. After each run, samples consisting of 2 layers (oil and water phases) were collected. The oil layer was qualitatively analyzed of its composition using a gas chromatography-mass spectrometry (GC-MS) apparatus, while the organic carbon content in water layer was analyzed using a total organic carbon (TOC) analyzer. Results obtained under these conditions indicated highly selective conversion of limonene especially into its isomers.
