← ScienceWhich outcome occurs when supercritical CO2 extraction pressure drops too rapidly?
A)Extraction material remains heavily contaminated
B)Selective solvation efficiency diminishes drastically
C)Azeotrope formation risk increases sharply
D)Solute precipitates, clogging the system instantly✓
💡 Explanation
Rapid pressure drop exceeding solute solubility causes precipitation because the phase behavior changes dramatically via retrograde condensation. Therefore, blockages happen rather than inefficiencies, because solubility is more affected than azeotropy by the rapid change.
