Versuchsvorschrift

A mixture of 1,2,3-propanetricarboxylic acid (25 g), cyclohexanol (55 g), and p-toluenesulfonic acid (100 mg) in toluene (500 mL) was refluxed for 2 days and water removed from the reaction mixture. After reaction was complete, solvent was removed in vacuuo to yield a viscous oil. The crude material was redissolved in heptane and passed through a pad of silica gel to obtain 1,2,3-propanetricarboxylic acid tricyclohexyl ester (50 g) as a pale yellow oil.
