Versuchsvorschrift

Trimethylammonium acetonitrile chloride (1.0 g, 0.007435 mole) was dissolved in methanol (20 ml) in a test tube. Sodium laurate (1.65 g, 0.007435 mole) was dissolved in boiling methanol (50 ml) and the two solutions mixed. The solution was evaporated to dryness and the solid heated with ethanol (60 ml). A granular precipitate of sodium chloride settled out and was filtered off, but less than the theorectical amount was obtained. The ethanolic solution was evaporated to dryness, azeotroped twice with IPA to give a lumpy solid containing white and fawn components (2.08 g, yield 93%). 'H NMR (σ, D2O) 0.85 (t, 3H, CH3-) 1.3 (s, I6H, CH3 -(CH2)8), 1.55 (m, 2H, CH2CH2CO-) 3.4 (s, 9H, (CH3)3N+) ppm. The ratio of quat to laurate was 1.3:1.
