The Soybean Project

This overview of The Soybean Project by Joshua Potvin discusses the experimental work in soybean oil's acrylation and polymerization processes. It covers the project's goals, experimental setups, results, and personal reflections on the journey through the Honors Program and First-Year Mentor Program. The findings highlight the intricacies of optimizing polymer reactions, including RAFT mechanisms and the challenges faced. This project offers valuable insights into practical research in chemical engineering and the collaborative nature of scientific inquiry.

  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

  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

  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
