OBJECTIVES
Acetylation Reaction Protocol & Film Preparation
REPEAT PROCEDURE ABOVE FOUR TIMES TO PREPARE FOUR FILMS
Acetylation Reaction Calculations1:1 HoAc Reaction Ratio: MW R-CH2CHOH-R: 44.00 g/mol MW Acetic Acid (HoAc): 60.00 g/mol 1.0g PVOH × (1 mol PVOH/44.00g PVOH) × (1 mol HoAc/1 mol PVOH) × (60.00g HoAc/1 mol HoAc) = 1.36g HoAc 1.36g HoAc × (1mL HoAc/1.05g HoAc)= 1.30mL HoAc 20% HoAc Reaction Ratio: MW R-CH2CHOH-R: 44.00 g/mol MW Acetic Acid (HoAc): 60.00 g/mol 1.0g PVOH × (1 mol PVOH/44.00g PVOH) × (0.2 mol HoAc/1 mol PVOH) × (60.00g HoAc/1 mol HoAc) = 0.27g HoAc 0.27g HoAc × (1mL HoAc/1.05g HoAc)= 0.26mL HoAc 40% HoAc Reaction Ratio: MW R-CH2CHOH-R: 44.00 g/mol MW Acetic Acid (HoAc): 60.00 g/mol 1.0g PVOH × (1 mol PVOH/44.00g PVOH) × (0.4 mol HoAc/1 mol PVOH) × (60.00g HoAc/1 mol HoAc) = 0.55g HoAc 0.55g HoAc × (1mL HoAc/1.05g HoAc)= 0.52mL HoAc 60% HoAc Reaction Ratio: MW R-CH2CHOH-R: 44.00 g/mol MW Acetic Acid (HoAc): 60.00 g/mol 1.0g PVOH × (1 mol PVOH/44.00g PVOH) × (0.6 mol HoAc/1 mol PVOH) × (60.00g HoAc/1 mol HoAc) = 0.82g HoAc 0.82g HoAc × (1mL HoAc/1.05g HoAc)= 0.78mL HoAc |
