Linseed oil elastic coatings than linseed oil itself. Soybean oil can be treated similarly, but converts more slowly. On the other hand, tung oil converts very quickly, being complete in minutes at 260 °C. Coatings prepared from stand oils are less prone to yellowing than are coatings derived from the parent oils. Boiled linseed oil is a combination of raw linseed oil, stand oil (see above), and metallic dryers (catalysts to accelerate drying). In the Medieval era, linseed oil was boiled with lead oxide (litharge) to give a product called boiled linseed oil. The lead oxide forms lead "soaps" (lead oxide is
Palm oil for biodiesels. Hydrodeoxygenated biodiesel is produced by direct hydrogenolysis of the fat into alkanes and propane. The world's largest palm oil biodiesel plant is the €550 million Finnish-operated Neste Oil biodiesel plant in Singapore, which opened in 2011 with a capacity of 800,000 tons per year and produces hydrodeoxygenated NEXBTL biodiesel from palm oil imported from Malaysia and Indonesia. Significant amounts of palm oil exports to Europe are converted to biodiesel (as of early 2018: Indonesia: 40%, Malaysia 30%).. In 2014, almost half of all the palm oil in Europe was burnt as car and truck fuel. As of 2018,
