  1. The Soybean Project Joshua Potvin

  2. Overview • Introduction • Background • AESBO/PAESBO • Experimental • Results/Discussion • Personal Experience • Questions?

  3. Introduction • Freshman • Honors Program • First-Year Mentor Program • Soybean Project • Goals • Acrylation • Polymerization • Optimization For pilot plant

  4. Background • Soybean Oil • In pilot plant phase • Acrylation • Kinetics • Polymerization • RAFT • Crashing/Recovery

  5. AESBO- Experimental • Setup: • Originally • Everything at once • Including solvent • Longer • Big Reactor • Aliquots and NMR • Terminal Methyl ~ 9 • Glycerol back bone ~ 4 • New Setup (Kinetics) • ESBO and Ethanox 330 • Melt • Amberlyst 15 • Mix • 1st Magnetic Stir Bars • 2nd Mechanical Stirring • Acrylic Acid (2.5 functionality) • 8 hrs

  6. AESBO-Experimental • Three Reactions • Acrylation • Hydrolysis • Polymerization

  7. PAESBO- Experimental • Second Part of Semester • Big Reactor • RAFT- • 4:1 Solvent to Monomer • CTA and Initiator • 1 : 0.65 • Purging • Polymerization • 2 hr 20 min. Ethanox • Crashing • 2 hrs 30 min. • Water/ Methanol • Recovery • AESBO settled at the bottom • Crosslinking

  8. AESBO- Results • First Trial: • Cross-linked • Kinetics

  9. AESBO-Results

  10. AESBO-Results

  11. AESBO-Results

  12. ESO-Viscosity Viscosity c Pa RPM

  13. PAESBO-Mechanism • RAFT Mechanism • Initiator • Free Radicals • Attacks Monomer • CTA • Adds monomer • Propagates • Continues until all monomer is used up • Crosslinking • Crashing • Goal • What helps crash PAESBO the best? • Many ways • Methanol • Water • Methanol/water • Methanol/Ethanol/Water • Retrieval

  14. PAESBO-Results

  15. PAESBO-Results

  16. PAESBO-Results • Viscosity 60°C 30°C 75°C

  17. PAESBO- Results • GPC is unavailable for my samples since the GPC machine was down while I have been working on polymerization.

  18. Personal Experience Things I Liked Things I did not Like “Too much” independence at times • Independence • First-hand experience • Working as a group • Working with Austin • The project as a whole

  19. Personal Experience • What I learned: • My career interests • How polymerization works • What research in chemical engineering is like • How to think better for myself • How to better work in a group

  20. Questions?
