Combined Reaction Distillation Units
Goel Glass designs and fabricates modular Reaction Distillation Units that combine the synthesis capabilities of a stirred reactor with the fractionation precision of an overhead packed distillation column. This versatile dual-purpose configuration enables chemists and process engineers to synthesize reaction intermediates and continuously drive reversible equilibrium reactions forward by simultaneously stripping out by-products or lower-boiling condensates.
Built entirely from thermal shock resistant Borosilicate 3.3 and virgin PTFE wetted seals, the unit features an agitated reaction vessel, an overhead packed column section with high-efficiency raschig packing, an electromagnetic reflux divider with digital cycle control, and a primary condenser coupled with an auxiliary sub-cooler. The system delivers complete operational flexibility, transitioning seamlessly between simple reflux reaction, vacuum fractional distillation, or simultaneous reactive distillation.

Key Engineering Features
- Multi-Function Hybrid Design: Functions independently as a batch reactor, fractionator, or coupled reactive distillation unit.
- Integrated Fractionating Column: Packed glass column section provides high separation efficiency for overhead cuts.
- Zero Contamination Guarantee: Only high-purity Borosilicate 3.3 and virgin PTFE contact reaction mixtures and vapors.
- Complete Process Visibility: Unrestricted visual observation of foaming, phase change, reaction kinetics, and reflux dynamics.
Industrial Applications
- Equilibrium Reactions: Esterification and acetalization with continuous azeotropic water removal.
- Solvent Exchange & Stripping: Reaction solvent removal followed by immediate product purification.
- Specialty Chemical Pilot Trials: Multi-step batch synthesis where reaction and fractional purification happen in one vessel.
- Vacuum Distillation of Synthesized APIs: Isolating delicate active compounds immediately upon completion of agitation.
