Chemistry C7 - Producing Chemicals

HideShow resource information

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


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

Separation of products

  • chemical reactions usually produce the product you want,
