Embodiment 2
[0057] Example 2: Sorbitol EO of Example 1 114 Amination of hexasulfate
[0058] Weigh sorbitol EO into a 200 mL glass liner 114 Hexasulfate (61.3 g of 90% active, 0.0095 mol) and 3-(dimethylamino)propylamine ("DMAPA" 18.5 g, 0.181 mol). The liner was heated in a swinging autoclave under nitrogen at 152 kPa (150 psig) until the temperature reached 165°C and held at 165°C for 2 hours. Cool to room temperature (20°C to 25°C). The material was extracted with 150 mL of dichloromethane and centrifuged until the salts were separated. The supernatant was transferred to a 500 mL round bottom flask and evaporated using a rotary evaporator at 50 °C until most (less than 5 mL) of the solvent was removed. Excess amine was removed by heating with a Kugelrohr apparatus at 120° C. and 133 Pa (1 mmHg) for 30 minutes to give 47.8 g of a brown hard solid. Proton NMR (500MHz or 300MHz; pulse sequence: s2pul, solvent D 2 O; relaxation delay 0.300 s, pulse 45.0; acquisition time 3.744 s) sho...
Embodiment 3
[0059] Embodiment 3: the quaternization of the amine sulfate of embodiment 2
[0060] In a 500 mL round bottom flask equipped with a magnetic stirring bar, aminated sorbitol EO 114 Dissolve in 100 g of dichloromethane and cool with an ice bath until the temperature reaches 10°C. The solution was adjusted to pH 12 with sodium methoxide (25% in methanol). To the solution was added iodomethane (15.0 g, 0.106 mol). The flask was stoppered and the solution was stirred overnight (approximately 14 hours). The solution was evaporated with a Kugelrohr apparatus at 50°C and 133 Pa (1 mmHg) to give 66 g of a sticky brown solid. Proton NMR (500MHz or 300MHz; pulse sequence: s2pul, solvent D 2 O; relaxation delay 1.000 s, pulse 45.0, acquisition time 2.345 s) shows complete quaternization of nitrogen in all amine capping units.
