UNIT 10:CHEMISTRY OF PRODUCTION
Chemistry of production
It is one of the country’s largest and safest manufacturing
industries.
The UK chemical industry has a turnover of over £57 billion a year and employs
nearly 200,000 people.
Why are chemicals so important?
Everything you use is made from chemicals.
The manufacture and production of these
chemicals is essential in everyday life.
Important chemical processesHaber Process = Ammonia
eg fertilisers, cleaning products
Important chemical processesContact Process = Sulfuric acid
eg dyes and pigments, pharmaceuticals, antifreeze
Important chemical processesElectrolysis of brine = Chlorine and hydrogen
eg disinfecting drinking water,
textiles, paper products
Important chemical processesFermentation = Ethanol
eg perfumes
Chemical processesA Chemical process is a method of changing one
or more chemicals or chemical compounds.
All Chemicals are produced using the same steps/processes.
ReactionsChemical reactions happen all the time and they
are affected by a number of factors.
ConditionsAll reactions need specific conditions in order for
them to produce a high yield.
A high yield will result in more money for a
company and also more chemicals for further
production.
The Contact process is used to produce
Sulfuric acid.
What are the dangers of chemicals?
Chemicals can be very dangerous if they are not handled correctly. This can lead to:
fires
explosions
leakages
Release of toxic or hazardous materials that can cause
illness, injury, disability or death.
Universal hazard symbols are used to identify the dangers of chemicals in the laboratory or
in transit.
Being greenChemicals are useful, but also very polluting and
dangerous.How can we protect our environment?
What will you learn?
About a variety of chemical processes.
Why and where chemical plants
are located.
How waste treatment methods
can be used to minimise the
environmental impact of a
chemical process.
The factors that govern the rate and yield of a
chemical process.
How the chemical industry maintains a good safety record in the manufacture and
transport of chemicals.
