+    "protocol": "S1) provision of a reaction mixture comprising as reaction components S1a) a polyglycerol comprising at least two glycerol units; S1b) an oil based on a natural oil; S2) reaction of the reaction mixture by a transesterification in the presence of a basic catalyst to give the ester product.255.6g of rape oil, 74.4g of Polyglycerol-3 (Solvay Chemicals) and 0.03g of LiOH*H2O were initially introduced into a glass flask and heated to 235°C, while stirring. After 1 hour, a vacuum of 300 mbar was applied, and after a reaction time of 2 hours, the mixture was cooled.The components were mixed together and the mixture was rolled on a laboratory roll mill at 185°C for 5 min. The rolled sheets were investigated by the 'hot fogging test' at 60°C."
