You have correctly and competently followed the techniques and procedures to
prepare and test your aspirin. You have used vacuum filtration, filtration
through filter paper, solvent extraction and recrystallisation. You have
P5 Y
measured the melting point of the aspirin and carry out a mixed-melting point
measurement. You have drawn simple conclusions about the purity of the
samples based on the tests carried out.
You have researched the industrial production and testing of the solid and
P6 N describe the scale, equipment, testing and the raw materials used to produce
the solid. You have referenced sources but not linked them correctly.
You have demonstrated skilful application of techniques and procedures to
prepare and test your aspirin. You worked independently and safely. You have
M4 N
drawn detailed scientific conclusions on the purity of your samples. You have
not cited your sources correctly to support your conclusions.
You have researched the industrial production and testing of aspirin and
compared the similarities and differences in terms of the equipment and the
M5 N
raw materials but not the scale and purification used to with the techniques
and methods used to prepare and test your sample.
You have analysed the factors to give thorough explanations of how they affect
the yield and purity of aspirin organic solid. You have not analysed how those
factors will be relevant in the industrial context to ensure scalability. You have
commented on the reliability of the techniques used in terms of whether
D3 N
melting-point measurement, mixed-melting-point measurement and thin-layer
chromatography (TLC) are effective ways to assess whether the solid is pure
and explain the effectiveness of alternative testing methods used industrially

, Making Aspirin in Industry
Word equation: 2 hydroxybenzoic acid + ethanoic acid ----> aspirin + water
A common way of making aspirin is to use esterification reaction using salicylic acid and ethanoic acid
(the acid in vinegar) we can also use ethanoic carbohydrate instead of ethanoic acid (2)
In industry Aspirin tablets are manufactured in batches. Batch processes are flexible, and you can
handle large amounts of products (aspirin in this case) at once. Also, because it is a short process it
goes quicker. In industry. They filter aspirin to remove air and lumps before making it into tablets, it is
known as slugging. Also, in industry Aspirin must be tested for quality control. They do things like test
the hardness of the tablet to make sure it is not too fragile, and they test the disintegration of the
tablet to make sure it can dissolve. all production must come to a standstill when being tested for
quality, in this time the aspirin is stored or shipped to things like hospitals or pharmacies. This can
extend the time it takes to make aspirin compared to in a classroom lab. (1)
1. The reactor has reactants added into the into it and is mixed well at a hot temperature
between 88-92 degrees Celsius or 20 hours
2. acetyl salicylic acid is put in the cooling tanks and cooled to form more crystals.
3. the substances are cooled down, they are filtered to separate the solids from the liquids.
4. The product is then washed with water.
5. Then the aspirin is turned into droplets by spraying the rapid evaporation of the sprayed
droplets into solid powder by hot air at a certain temperature and pressure.
6. Freeze it so that it will have longer shelf life in pharmacies and shops
7. Corn starch, aspirin and lubricant are weighed and mixed and separated into units.
8. After ingredients are mixed well, the batches are forced through a mesh screen. Large batches
are filtered through Fitzpatrick mill. Remaining lubricants are added and blended softly in a
rotary granulator.
9. Mixture is compressed into tablets by single punch for small batches and rotary machine for
large scale product
