Calcium oxide (5.6 grams, 0.1 mole) was added to the cooled stirred mixture and after 30 minutes, the solid material (37.6 grams) was separated by filtration and 300 milliliters of water were added thereto. After one hour at reflux, the solution was cooled and acidified with 6N hydrochloric acid to precipitate 19.8 grams (92 percent yield) of tridecanoic acid.
