Abstract:
the content of this handout which describes the Techniques for transforming a
mixture of substances into two or more distinct components is intended for engineering
students, these techniques are intended for purification (by extraction of impurities from
the compound of interest), concentration (by eliminating part of the solvent) or
fractionation (by separating a complex mixture into several different mixtures).
A separation technique is always based on the use of a difference in properties
between the compound of interest (the one we are trying to isolate) and the rest of the
mixture. A good knowledge of the properties of the different components is therefore
essential in order to retain the method and the parameters that will guarantee a
successful separation.
The main objective of this handout is to train students in a wide range of skills
that will allow them to mix according to their sectors of activity, how to extract the
desired product by these separation methods in heavy chemistry, in fine chemistry, in
parachemicals, petrochemicals, etc
