Chemistry C7 - Producing Chemicals

Stages in producing chemicals

• preparation of feedstock
• synthesis
• separation of products
• monitoring the purity of product
• handling of by-products and wastes

Preparation of feedstock

• raw materials are needed e.g. crude oil, natural gas
• feedstocks are the actual reactants need e.g. hydrogen, ethanol
• raw materials usually have to be purified or changed in some way to make feedstock

Synthesis

• feedstocks are converted into products
• conditions have to be carefully controlled

Separation of products

• chemical reactions usually produce the product you want,…
