Ethyl ethanoate can be made by reacting ethanol with ethanoic acid in the presence 
of concentrated sulfuric acid. 
Method 
1. A mixture of ethanol, ethanoic acid, and concentrated sulfuric acid, with 
anti-bumping granules, is heated under reflux for 10 minutes. 
2. The apparatus is rearranged for distillation. 
3. The mixture is heated to collect the liquid that distils between 70 and 85 °C 
4. The distillate is placed in a separating funnel. Aqueous sodium carbonate is 
added, and a stopper ...

An organic ester compound, ethyl ethanoate, of acetic acid with ethyl alcohol, it is a colourless solution which is highly volatile, best known in glues and nail polish remover. This chemical is one of the simplest carboxylate esters with the widest range of uses. This compound liquid has a characteristically sweet, pleasant fruity odour. The chemical used for this experiment must be handled with extreme caution as they are highly corrosive and flammable. So, it is important to wear the right th...

Aspirin is a generic term for acetylsalicylic acid. This substance was first introduced in the late 1890s, that has become a ‘’non-steroidal anti-inflammatory drug’’, non-opioid analgesic and antiplatelet drug which is widely used for medicinal purposes. Aspirin will not react against the acetic conditions of the stomach, yet it is hydrolysed in the intestines as it will react on alkaline conditions to create ethanoate ions and salicylate. 
Aim: In this practical, an Aspirin will be made...

Unit 4: Esters. How can you 
make simple esters? 
Heating a mixture of ethanoic acid and ethanol with a 
few drops of concentrated sulfuric acid produces ethyl 
ethanoate 
Ethanoic acid + ethanol -> ethyl ethanoate + water 
CH3COOH + CH3CH2OH -> CH3COOCH2CH3 + H2O 
Starting materials: ethanol and ethanoic acid 
Catalyst: concentrated sulfuric acid 
Conditions: heat 
The concentrated sulfuric acid isn't written into the equation because it is a catalyst and therefore isn't consumed
