OP-2-16MICROWAVE-ASSISTED EPOXIDATION OF VEGETABLE OILSIN THE PRESENCE OF HYDROGEN PEROXIDEBogdal D., Prociak A., Michalowski S., Pala G.Chair of Polymer Chemistry and Technology, Cracow University of TechnologyUl. Warszawska 24, 31-155 Krakow, Polande-mail: pcbogdal@cyf-kr.edu.plA two-step process was applied for the preparation of rapeseed and linseed oilbasedpolyols. In the first step, unsaturated fatty acids in triglycerides reacted withhydrogen peroxide to form epoxidized oil. Through the epoxidation, the double bondsof the triglycerides were transformed into oxirane rings.OOOOOOmicrowaveH 2O 2catalystOOOOOOOOOIn the second step, the epoxidized oils were converted into the polyols usingmonoethylene glycol (MEG) or diethylene glycol (DEG). In the case of the polyolbased on rapeseed and linseed oil and the glycols both steps of the process(epoxidation and oxirane ring opening) were carried out under microwave irradiation.It allowed to reduce the reaction time of the epoxidation step ca. 60 %, and thehydroxylation step ca. 75 % in comparison to the process realised conventionally.References:[1].
