3. Continuous processes
In continuous operation, the aim is to limit the under-production of "heavy" terms, in particular by working with a high molar excess of RXH reactant in relation to the manufacturing stoichiometry of the first term. This molar ratio (with the possible additional thermal ballast effect of the solvent used) is generally high enough to allow the use of an adiabatic reactor, which is therefore not very sophisticated.
3.1 Schematic diagrams
A "continuous" process is preferred to a "batch" process in the following cases:
manufacture of low-molecular-weight, distillable products, which generally involves extensive recycling of the RXH reactant or the first term, which is easier in continuous operation;
