Receiving triacetin from sunflower oil

One of the promising types vegetable raw materials in Ukraine, which can be used for development resource-saving technologies, are oils. The products their processing serve as obtaining surface-active substances, production food additives, pharmaceutical products, detergents and cosmetics, biofuels additives. most common oil Ukraine is sunflower, which, like other oils, processed to form fatty acids salts. initial process hydrolysis. technological parameters sunflower hydrolysis under different conditions were studied. It was investigated that alkaline presence sodium hydroxide proceeds fastest comparison with thermal methods sulfuric acid superheated steam, conversion reaches 100 % 25th minute experiment, at a temperature 60 °C. waste this glycerol solution, obtain its esters purpose implementing zero-waste technology scheme. A method using proposed, consists esterification acetic acid, result triacetin formed – valuable product use many sectors national economy. In industry, known additive code E1518, humectant stabilizer preserve freshness, plasticizer binder thickener, solvent odor fixer. Due ability broken down into components absorbed without any side effects human body, safe use. reaction between solution glycerin water took place %, while selectivity target remained constant level 80 %. At same time, concentration did not affect either amount or value selectivity. As catalyst process, p-toluenesulfonic relatively small 1.0 by volume, so it significantly composition this, future, makes possible conduct additional purification from traces catalyst.
