How do we make new chemicals? Chemical Synthesis How do we make new chemicals? What raw materials from the Earth do we use to make chemical products.
give examples to illustrate the importance of chemical synthesis describe some of the key differences between large-scale manufacture of bulk chemicals and small-scale production of fine chemicals
Bulk chemicals: ammonia, sodium hydroxide, ethene and sulfuric acid Fine chemicals – drugs, pesticides, herbicides, liquid crystals for flat screen tvs. What differences are there between these chemicals?

Major stages in making chemicals A need for a chemical is identified. A “pilot plant” is set up to find out the requirements for production. Costs are considered and balanced with potential profit. A proper chemical plant is built costing millions of pounds but creating a lot of jobs.
