combustibility test, iodoform test, ester formation

ethyl alcohol chemical test

1. distilling flask: + 120ml decanted liquid

2. +pcs boiling chip (Silicon carbide)

3. cork at the top and long end of the flask

4. elevate using prong and s clamp

5. insert thermometer

ethyl alcohol distillation (distillation flask)

1. connect 2 rubber tubing at the hole

2. elevate using prong and s clamp

3. attach one end

4. 1st RT(lower part) water inlet

   2nd RT (upper part) water outlet

5. attach cork

Simple distillation assembly (condenser)

1. attach cork

2. connect the end of the condenser to the receiving flask by adapter

3. ensure cork

Simple distillation assembly (receiving flask)

1. heat the sx in distilling flask via alcohol lamp

2. heat only at 70-80 degrees celcius

3. wait collection ½ to 1/3 volume of the distillate

4. subject to chemical testing

simple distillation

1. watch glass, add 1 ml distillate

2. burn then sx

3. note color (blue)

combustion test

1. test tube add 1ml distillate

2. add 15 ml 10% potassium iodide

3. add 8ml sodium hypochlorite soln

4. heat at 60 deg c for 5 mins

5. shake occationally

6. note color (colorless)

iodoform test

1. test tube add 20 drops ethanol

2. place ice bath

3. add 10 drops conc acetic acid

4. 4. 5 drops conc sulfuric acid

5. warm the sx

6. note odor (plastic baloon)
