“2. Add 50mL of water and a small magnetic stir bar to the flask containing the sample. 3. Agitate for 15 minutes using a magnetic stirring device. Make sure the slurry is agitated sufficiently to stay suspended during this period. 4. Turn off the stirrer. 5. Add 20 mL of … Swirl to mix. 6. Add 25 ml of… Swirl to mix. 7. Let the slurry stand for 5 minutes… 8. Resume stirring.”

“12. Turn off the stirrer and let the slurry stand for 2.0 hours… 13. Resume stirring and titrate as in “11.” above.”

“As for the aqueous phase, 100 mg PVA and 15 mg CS or TMC were stirred in 5 ml water for 2 hours at room temperature until a clear solution was obtained. The organic phase was passed through a 0.22µm syringe filter to remove any un-dissolved solids and subsequently added drop-wise to the aqueous phase under constant stirring. The resulting micro-emulsion was kept under constant agitation on magnetic stirrer at 1,000 rpm for 1 hour…”

“This colloidal preparation was diluted to a volume of 50 ml by adding water drop wise under stirring conditions (1,000 rpm, magnetic stirrer), which resulted in nanoprecipitation.”

“The reaction mixture is stirred for 48 to 60 hr at room temperature (Note 7) and subsequently diluted with water (100mL) and hexane (300 mL). Stirring is continued for an additional 3 hr at room temperature.”

“…is added very slowly dropwise to the solution of the ester and stirring is continued for at least 1 hr after the complete addition of the DIBAH solution (Note12). Upon complete consumption of the ester, the crude reaction mixture is poured directly with vigorous stirring into 360 mL of…”

“The aldehyde solution is added dropwise at 0°C with vigorous stirring. After complete addition the reaction mixture is stirred for ca. 12 hr and allowed to warm…”
