Solid-liquid extraction is a separation process used to isolate compounds of interest from a solid matrix by dissolving them in a liquid solvent. When this process is conducted with the application of heat, it is termed "Hot Extraction." Elevating the temperature significantly alters the thermodynamics and kinetics of the extraction, making it one of the most efficient and widely used techniques in industries ranging from pharmaceuticals to food processing.
Laboratory scale:
Pilot/industrial scale:
Design parameters:
The ideal solvent should have high affinity for the target solute, low toxicity, high volatility (for easy removal), and an appropriate boiling point. Common solvents: solid liquid extraction hot
