The reaction is a fundamental operation of the chemical industry, allowing the production, from simple molecules (reagents), of increasingly complex compounds destined for a growing number of industries (chemistry, pharmacy etc).

The reactor is of the well-mixed type and operates in a batch process: the quantity of reagent is introduced at the start of processing in a single quantity or controlled over time. The reaction mixture is brought to the required temperature. The presence of a distillation column makes it possible to evaporate a solvent in the same reactor, to separate the reaction products once the desired conversion rate has been reached. At the end of processing the products of the reaction are collected after cooling.

The reactor also allows “batch” crystallizations to be performed, with the crystals then being separated from the mother liquor by filtration.
