REACTION OF ALCOHOLS

AIM:

The purpose of this experiment was to investigate the properties of the alcohols ethanol, 1-butanol, 2-butanol and 2-methyl-2-propanol, and to compare the reactivities of a series of isomeric alcohols (with the formula C4H9OH).

EQUIPMENT:

250 ml beaker
Thermometer
5 large test tubes
Bunsen, tripod and gauze mat
Dropper
Metal tongs
Graduated cylinder (10 ml)
5 ml sodium dichromate solution [Na2Cr2O7] 0.1 mol/L
5 ml sulfuric acid [H2SO4] 6 mol/L
2 ml potassium permanganate solution [KMnO4] 0.01 mol/L
4 pieces of sodium
6 ml ethanol [CH3CH2OH]
6 ml 2-methyl-2-propanol [(CH3)3COH]
6 ml 1-butanol [CH3CH2CH2CH2OH]
6 ml 2-butanol [CH3CH2CHOHCH3]

PROCEDURE:
Part A: Reaction of Alcohols with Oxidising Agents – Reaction with Dichromate Ion

1. 100 ml of water was heated to 80º in a 250 ml over a Bunsen.
2. The Bunsen was turned off.
3. 2 ml of ethanol, 1-butanol, 2-butanol, and 2-methyl-2-propanol were placed into 4 separately labelled test ...
