Appreciate that speciality chemicals such as
pharmaceutical drugs are widely used in our society.
This unit looks at how
speciality chemicals are developed, tested and marketed.
It also describes
the differences between batch manufacture used for speciality chemicals and
continuous manufacture used for making substances such as ammonia.

Be able to describe the differences between a batch and a
continuous process. Industrial case studies.
Be able to list the factors that affect the
cost of making and developing a pharmaceutical drug:
Be able to explain why pharmaceutical drugs need to be thoroughly tested before
they can be licensed for use.
Know that the raw
materials for speciality chemicals such as pharmaceuticals can be either made
synthetically or extracted from plants.
Be able to explain why it is important to
manufacture pharmaceutical drugs to be as pure as possible.
Be able to describe how melting
point, boiling point and thin layer chromatography can be used to establish the
purity of a compound.
Be able to explain why batch processes are often used for the production of
pharmaceutical drugs but continuous processes are used to produce chemicals
such as ammonia.
HT only: Evaluate the advantages and disadvantages of batch and
continuous manufacturing processes given relevant data and information.
Be able to explain why it is often expensive to make and develop new pharmaceutical
HT only: Be able to
explain why it is difficult to test and develop new pharmaceutical
drugs that are safe to use.
Be able to describe how chemicals are extracted from plant
Be able to interpret melting point, boiling point and chromatographic
data relating to the purity of a substance.
