Procedure

Trimethylammonium acetonitrile (1.0 g, 0.007435 mole) and sodium dodecyl sulphate (2.14 g, 0.007435 mole) were weighed into a 250 ml rotary evaporator flask. Methanol (100 ml) was added and the mixture heated until a clear solution was obtained. The methanol was evaporated off and IPA (150 ml) was added, and the mixture warmed. A granular precipitate of sodium chloride separated out and was filtered off. The amount obtained was less than the theoretical amount. The IPA-soluble fraction was evaporated to dryness to give 3.4 g of solid and this was further dried under vacuum. 'H NMR (σ, D2O) 0.9 (t, 3H, CH3 --C), 1.3 (m, 18H, CH3 (CH9) 1.7 (m, 2H, CH2CH2SO4 -), 3.4 (s, 9H, (CH3)3N+), 4.1 ppm (t, 2H, --CH2SO4-) ppm. The ratio of quaternary to dodecyl sulphate was 1.03:1.
