Abstract

Processo de desterpenação química pela oxidação catalítica do óleo essencial de Citrus e produto. A presente invenção diz respeito a um processo de desterpenação química obtida pela oxidação catalítica do óleo essencial de frutas cítricas que utiliza um agente oxidante e catalisadores heterogêneos capazes de promover a oxidação controlada do óleo essencial de citrus. A presente invenção revela ainda um óleo essencial modificado derivado do processo supracitado. Este óleo contém limoneno residual e uma alguma quantidade de produtos oxigenados derivados da oxidação controlada do limoneno, tais como epóxidos do limoneno, carveol e carvona.Chemical deterpenation process by catalytic oxidation of Citrus essential oil and product. The present invention relates to a chemical deterpenation process obtained by catalytic oxidation of citrus essential oil using a oxidizing agent and heterogeneous catalysts capable of promoting controlled oxidation of citrus essential oil. The present invention further discloses a modified essential oil derived from the above process. This oil contains residual limonene and some amount of oxygenated products derived from controlled limonene oxidation, such as limonene epoxides, carveol and carvone.
