Examples
Embodiment 1
[0069] Diisopropyl D-tartrate was purchased from Aldrich Chemical Company and used as received. The compound is a low viscosity, clear, colorless liquid with no detectable odor.
Embodiment 2
[0071] Dibutyl L-tartrate was purchased from TCI America and used as received. The compound is a low viscosity, clear, colorless liquid with a slight, pleasant odour.
Embodiment 3
[0073] Diisobutyl DL-tartrate was prepared by esterifying DL-tartrate with isobutyl alcohol. To a three necked 1 L round bottom flask equipped with reflux condenser, Dean-Stark trap, septum, thermocouple and mechanical stirrer was added DL-tartaric acid (101.85 g), 2-methyl-1-propanol (250 ml) and Amberlyst(R) 15 ion exchange resin (15.3 g). The mixture was placed under a nitrogen atmosphere and heated to reflux. At 105°C, 2 phases started to collect in the Dean-Stark collector. The reaction temperature was maintained at 105°C for 2 hours and water was continuously removed through a Dean-Stark trap. As collection in the Dean-Stark trap slowed, the reaction temperature was raised to 120°C over 3 hours. At this point, no more water is being collected in the Dean-Stark collector. The product was separated from the catalyst by filtration, and the catalyst was washed with diethyl ether. The resulting pale yellow liquid was washed twice with saturated sodium bicarbonate (200ml)...
