The glycerol phase, obtained as a by-product during the production of biodiesel from sunflower seeds, was utilized for preparation of alkyd paints. Using appropriate treatment, free fatty acids and crude glycerol were obtained from all organic substances in the glycerol phase. Medium and long oil alkyd resins were prepared by esterification of phthalic anhydride with the free fatty acids and crude glycerol. By the way of comparison, two reference types of alkyd resins with sunflower oil fatty acids, glycerol, and phthalic anhydride were prepared. Some basic properties of alkyds were determined. Their structure was confirmed by FTIR. All alkyd resins were used for formulation of white paints. Some properties such as color, adhesion, solid content, hardness, drying time, and chemical resistance were evaluated. Results showed that all organic substances in the glycerol phase can be successfully used for preparation of alkyd paints.

从葵花籽生产生物柴油过程中作为副产物获得的甘油相可用于制备醇酸涂料。使用适当的处理，可以从甘油相中的所有有机物质中获得游离脂肪酸和粗甘油。中和长油醇酸树脂是通过邻苯二甲酸酐与游离脂肪酸和粗甘油的酯化制备的。通过比较，制备了两种参考类型的具有葵花籽油脂肪酸，甘油和邻苯二甲酸酐的醇酸树脂。确定了醇酸树脂的一些基本性质。FTIR证实了它们的结构。所有的醇酸树脂都用于配制白色涂料。评价了一些性质，例如颜色，粘附性，固体含量，硬度，干燥时间和耐化学性。
