Versuchsvorschrift
About 28.1 g (0.1 mole) of isostearic acid and 23.5 g (0.1 mol) of the CL-THAM adduct of Example 4 were added to a reaction flask and heated to 180° C. to distill off the water of reaction. The reaction mixture was heated at 180° C. for four hours with mild nitrogen sparging. An infrared analysis of the product showed the desired ester oxazoline. The residue was diluted in solvent 150 neutral mineral oil to make a 50% active ingredient solution and was collected.
