Toll distillation: synthesis

Speichim Processing handles reactive distillation, which combines reaction and distillation, at its Saint-Vulbas site. A site which holds the necessary authorizations in its prefecture decree Several chemical reactions are well suited to this technique, especially balanced reactions.

The following reactions are examples:

• Esterification
• Transesterification
• Transanhydridation

The integration of product synthesis and separation by distillation improves chemical conversion by shifting the reaction equilibrium thanks to the recycling of non-converted raw materials.

The process takes place directly in one or several distillation columns without using a reactor. In the era of process intensification, or the reduction of the industrial machinery’s size this century-old technique is increasingly justified.
