-
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.
-
Practical work and research
investigations-activities which you have done which help in revision may
have included:
-
Industrial case studies that
you did.
-
Practical extraction of a natural oil from a
plant.
-
Research plants and animals used as sources of drugs.
-
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
drugs.
-
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
sources:
-
Be able to interpret melting point, boiling point and chromatographic
data relating to the purity of a substance.
