The unique attributes of the water molecules extend into the higher temperature region from 100 - 300 deg C. As temperature increases the Dielectric Constant lowers to approach that of more polar molecules such as ethanol and acetone. Image via Core Separations With...

Subcritical Water Extraction is considered an environmentally responsible "green chemistry" due to some key operation considerations: 1. Minimal chemical consumption during the extraction process (water is the main solvent used). 2. Power usage for...
