The dried high DS starch hexanoate described above (Ex. 12, 71.3 g), ethanol (65.2 g), and n-propyl acetate (65.2 g) were charged to a 500 mL round bottom flask, equipped with condenser, overhead stirrer, nitrogen blanket, thermocouple and heating mantle. The mixture was heated to 60° C. for about 1 hr. to form a transparent, low viscosity solution at 30 wt % solids in 50/50 ethanol/n-propyl acetate.
