The product is finally distilled at reduced pressure to give methyl ricinolate of about 99.5% purity. Ricinoleic Acid (Note 1) Castor oil fat acids were dissolved in acetone (20cc/Gr) and cooled successively to -20° C and -70° C. (Note 2) The precipitate formed was removed by filtration and the last traces of solvent were removed from the product by warming to below 60° in vacuo.
Ethanol fuel - Wikipedia
Ethanol fuel is ethyl alcohol, the same type of alcohol found in alcoholic beverages, used as fuel. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. The first production car running entirely on ethanol was the Fiat 147, introduced inFiat.
