Principle of Working:

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 (fixed or programmed according to time). 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, or to remove one of the products of the reaction (in the case of reversible reactions to displace the thermodynamic equilibrium) with miscible or immiscible products (in the case of heteroazeotropic distillation with recycling one phase and removal the other phase of the distillate production). At the end of processing the products of the reaction are collected after cooling.
The reactor also allows “batch” crystallizations to be performed, and the crystals then separated from the mother liquor by filtration.
