Producing chemicals:

Preparation of feedstock -> synthesis -> separation of products -> monitoring purity -> Dealing with by-products and waste

1) Preparation of feedstock:

Raw materials = naturally occurring substances that are needed

Feed-stocks = the actual reactants required for the process

Raw materials have to be purified or changed in some way to be able to produce the feedstock

2) Synthesis:

Using chemical processes, the feed-stocks are converted into the products.

It's important for the conditions to be carefully controlled to ensure that the reaction happens and also at a sensible rate

3) Separation of products:

During chemicals reactions, you will usually produce the chemical/substance that you want and require, but you may also produce some other chemicals that you may not necessarily want, known as by-products.

By-products can be useful, or they could be…
