With the exception of fermented alcohols, non-aqueous solvents are derived from oil, gas and other fossil fuel sources.
These are also known as organic solvents as the word organic indicates that the materials are derived from carbon.
The production of organic solvents takes place at the refinery, where a number of processes such as fractional distillation produce pure solvents for use in a large number of applications.
Our colleagues in the European Chemical Industry Council (Cefic) have produced an interactive flowchart which will guide you through the manufacturing processes involved in the production of commonly used solvents. Click on the link below to view
