ÓLEOS ESSENCIAIS E VEGETAIS: MATÉRIAS-PRIMAS PARA FABRICAÇÃO DE BIOPRODUTOS NAS AULAS DE QUÍMICA ORGÂNICA EXPERIMENTAL

Abstract

ESSENTIAL AND VEGETABLE OILS: RAW MATERIALS FOR THE MANUFACTURE OF BIOPRODUCTS IN CLASSES IN EXPERIMENTAL ORGANIC CHEMISTRY. A schedule was prepared for three undergraduate classes for the discipline of experimental organic chemistry for obtaining bioproducts. As natural raw materials, lavender flowers and cinnamon peels were used to obtain hydrolates and essential oils (Class 1), coconut and avocado pulp to obtain vegetable oils and annatto seeds to obtain a natural dye (Class 2). Cosmetic bioproducts (Class 3), body emulsions similar to those found on the market, were obtained from the mixture of essential and vegetable oils and the addition of natural dye. The raw materials obtained can also be used in other classes of the discipline, complying with the principles of Green Chemistry. Essential oils, for example, can be used as samples for Thin Layer Chromatography (TLC) classes and vegetable oils for the production of biodiesel.
