We have to use nearly pure acetone for organic solution.
Acetone is produced directly or indirectly from propylene.
After several processes.
Products we have are 40% of acetone and water solution.
How we get nearly pure acetone?
Factors to be considered:
Feasibility
Product value
Cost
Product quality
selectivity
Possible Process:
Distillation
Extraction
Extractive distillation
Extraction(1)+Distillation
Extraction(2)+Distillation
Mainly involved in separation process
-Extraction (추출) : liquid – liquid
Driving force : distribution coeff.
-Distillation (증류) : vapor-liquid
Driving force : Vapor pressure
