Unit 4 Assignment B
Introduction
In this assignment I will be preparing and testing the purity of a sample of ethyl
ethanoate and then draw conclusions based on my results. I will also report
the industrial manufacturing and testing of ethyl ethanoate. Furthermore, I will
put the laboratory and industrial manufacture and testing side by side with
each other comparing the similarities and differences. As well as this, I will
draw detailed conclusions on the preparation and testing of the purity of an
organic liquid which we demonstrated in class.
What is ethyl ethanoate?
An ester is an organic compound made by replacing the hydrogen of an acid by
an alkyl or other organic group it is the product of the condensation reaction
between an alcohol and carboxylic acid. Ethyl ethanoate is one of the most
common esters. Some uses of ethyl ethanoate are for nail polish remover,
glues, lacquer thinners and perfumes. Ethanoic acid and ethanol react together
to create ethyl ethanoate; sulphuric acid is added to speed up the slow
process.
The equation:
Ethanoic acid + ethanol = ethyl ethanoate + water
CHCOOH + C2H5OH = CH3COOC2H5 + H2O
Risk Assessment
Risk Hazard Prevention Measures taken
Ethyl ethanoate/ Corrosive Wear gloves and If the chemical
Ethanoic acid googles gets onto the
skin, wash the
area for at least
10 minutes and
, seek medical
advice
Ethanol Highly flammable Use correct If this chemical
equipment and gets on the skin
discharge wash the area in
chemicals in an warm water and
appropriate way soap
Water Spills Clean up straight Handle
away, warn other equipment with
care
Anhydrous If inhaled can Avoid inhaling Seek medical
sodium cause coughing help
carbonate/ and shortness of
anhydrous breath
calcium chloride
Quich-fit Broken glass Handle glassware Run area under
apparatus with care, if there water and seek
are any chips in medical help
the glassware do
not use
Water pump Spillages Handle with care, Ensure
clean up as soon everything is in
as possible, warn place properly
other if there are
any spillages
Heating mantle Burns Handle with care, Run the burn
only touch when under cold water
turned off/cooled for 10 minutes
down
Anti-bumping Corrosive to skin, Ensure gloves If granules get on
granules eyes and and googles are your skin run
respiratory worn under warm
system water
Preparation of ethyl ethanoate
Health and safety
Lab coat – protect clothing
Googles – protect eyes
