Evaluation Of Liquid Extraction Potentials For Downstream Separation Of 1,3-Propanediol, Janusz J. Malinowski

Janusz J. Malinowski

The application of liquid-liquid extraction for the downstream separation of 1,3-propanediol from dilute aqueous solutions has been tested. Preliminary solvent screening was performed using the group contribution method. Experimental verification of the predictions revealed that the distribution of 1,3-propanediol into organic solvents is not good enough to make simple extraction efficient.

For each proposition, the senior management included a full outline of the current status, a plan of action, the name of the staff member responsible, and a time line. An external assessment of implementation of each proposition and of the impact on achievement was undertaken. The propositions, clustered in the areas of vision, statement of beliefs, student learning goals, definition, social issues, learning issues, clarification of roles and responsibilities, integration of information delivery systems, community-based information infrastructure, and assessment, are …
