Explain the structure of benzene using sigma and pi bonding, providing evidence
for the structure.
The laboratory production of ethyl ethanoate, also known as ethyl acetate,
involves the reaction between ethanol and acetic acid in the presence of a catalyst
such as sulfuric acid. This process is known as esterification and results in the
formation of an ester, which is a type of organic compound with a characteristic
sweet smell.
The reaction equation for the production of ethyl ethanoate is as follows:
CH3CH2OH + CH3COOH → CH3COOCH2CH3 + H2O
Ethyl ethanoate has a wide range of commercial uses, including as a solvent for
paints, varnishes, and lacquers. It is also used in the production of adhesives,
artificial leather, and photographic films. In the food industry, it is used as a
flavoring agent and as a solvent for flavorings and perfumes.
Another example of an ester with commercial uses is methyl salicylate, which is
commonly used in topical pain relief products such as muscle rubs and creams. It is
also used as a flavoring agent in food products such as chewing gum. The
laboratory production of esters involves the reaction between a carboxylic acid
and an alcohol in the presence of a catalyst. Esters are commonly used in the
fragrance and flavor industry, as well as in the production of solvents, plastics, and
resins. One example of a commercial use of esters is in the production of ethyl
ethanoate, also known as ethyl acetate, which is used as a solvent for paints,
varnishes, and lacquers.
To produce ethyl ethanoate in the laboratory, the following apparatus and
chemical reagents are required:
- Round-bottom flask
, - Reflux condenser
- Separatory funnel
- Calcium chloride drying agent
- Ethanoic acid (glacial)
- Ethanol
- Concentrated sulfuric acid
Firstly, 50 mL of glacial ethanoic acid is added to a round-bottom flask. Then, 50
mL of ethanol is added to a separatory funnel. A few drops of concentrated sulfuric
acid are added to the ethanol to act as a catalyst. The ethanol is slowly added to
the flask containing the ethanoic acid while stirring. The mixture is then heated
under reflux for one hour.
After one hour, the mixture is allowed to cool and transferred to a separatory
funnel. The organic layer (ethyl ethanoate) is separated from the aqueous layer
(remaining acid and water) using a separatory funnel. The organic layer is then
dried using calcium chloride drying agent.
Health and safety considerations must be taken into account when carrying out
this experiment. A risk assessment form should be completed prior to conducting
the experiment to identify potential hazards and risks associated with each step of
the procedure. Some potential hazards include exposure to concentrated sulfuric
acid, flammable ethanol, and hot glassware.
Ethyl ethanoate, also known as ethyl acetate, is a colorless liquid with a fruity odor.
It is commonly used as a solvent in various industries such as pharmaceuticals,
food, and cosmetics. In the laboratory, ethyl ethanoate can be produced by the
reaction of ethanol and acetic acid in the presence of a catalyst.
The mixture of reactants and catalysts were reacted by reflux. Reflux is a technique
used in chemistry to heat a reaction mixture while continually cooling the vapors
that are produced. This allows for the reaction to proceed at a constant
temperature and prevents the loss of volatile components.
