Objective

To prepare new films containing phenol, to purify the quaternary ammonium salt prepared on Monday, and to take an NMR of the purified salt.

Description

Phenol Film Calculations

Phenol Film Preparations

1. Prepare the 10% film by dissolving 0.214 g phenol and 1 g PVOH in 10 mL water.
2. Allow to dissolve on the hot plate, then add 1 mL glutaraldehyde, allow to stir for 2-3 minutes, then pour into an evaporating dish and allow to dissolve over the weekend.
3. Prepare a stock solution of 0.214 g phenol in 10 mL water.
4. Allow to dissolve.

Quaternary Ammonium Salt Purification

1. Turn off the heat on the round bottom flask containing the reaction and remove from the heating mantle.
2. Fill a beaker with 100 mL ethyl acetate.
3. Place on ice.
4. Add the product drop-wise
5. Filter and collect precipitate.
