Molecular distillation and short path distillation are essentially the same process.
They are characterized by the use of high vacuum conditions and a short distance between the evaporation and condensation surfaces.
This method is particularly effective for heat-sensitive materials, minimizing thermal stress and providing a gentle distillation process.
4 Key Differences Explained
Process Similarities
Both molecular and short path distillation require a high vacuum to operate effectively.
The short path aspect refers to the minimal distance the molecules travel from the evaporation surface to the condensation surface, typically less than 300mm.
This short distance ensures minimal thermal degradation of the product, making it suitable for heat-sensitive materials.
Operational Differences
While the text suggests a distinction in terms of vacuum pressure and analytical versus practical application, the core process remains the same.
Molecular distillation, as described, is a type of short path distillation that operates under extremely low vacuum pressures.
The distinction between an analytical technique and a practical application in distillation might relate more to the scale and purpose of the distillation rather than the fundamental process itself.
Applications
This distillation method is particularly useful for compounds that are sensitive to heat, such as cannabinoids and other high molecular weight compounds.
The short residence time and low evaporation temperatures ensure that the product is not subjected to high thermal stress, preserving its integrity and quality.
Conclusion
In conclusion, while there might be nuances in the scale or specific applications of molecular and short path distillation, the core process and principles are identical.
They focus on a high vacuum environment and a short path for the distillation of heat-sensitive materials.
