Application of Alkyd Resins Based on All Organic Substances in the Glycerol Phase from Biodiesel Production

For the purposes of the present work, the glycerol phase, that is separated as side product from the biodiesel production from cooking oil was used. After its treatment with acid, two liquid fractions were obtained - crude glycerol and organic matter. These two fractions were used to obtain two kinds of alkyd resins by the method of alcoholysis, heating was by microwaves. Obtained alkyd resins were used in formulation of white paints as binding substance. It was found that the main characteristics, like adhesion, flexibility, drying duration and chemical resistance, of the samples were comparable to these of the samples of standard soy paint and could successfully be used when the requirements towards color brightness are not high.
