PhD chemist, experienced in the development and scale up of chemical processes. I have worked at Dow Chemical and DuPont as an industrial R&D chemist, and then at Michigan State University as a Research Assistant Professor performing contract R&D and STEM teaching roles. I am a heavy user of Word, Excel, and PowerPoint. I have extensive experience writing, proofreading, and editing reports and academic papers. I can incorporate chemical structures and equations into documents for technical presentations. I do number crunching where graphs are needed to clearly communicate the story of what data is telling us. I create PowerPoint slide decks for communicating project results to managers. Need a tutor for organic chem? Need help with that presentation? I know it can be stressful. I'm here to help! I can help get your slides looking great, and I can also give you constructive feedback on your presentation. The key is building confidence. My areas of expertise include: • Applied catalysis and catalyst optimization • Synthetic organic and inorganic chemistry • Organometallic synthesis from my academic PhD work • Polymer processing and modification • Process optimization and scale up • Chemical purification - crystallization, filtration, column chromatography, distillation • Chemical analyses - including GC, HPLC, NMR, FTIR, GC/mass spec, Karl Fischer titration, pH calibration, ion selective electrode for halides • Technical and creative writing • STEM teacher and chemistry tutor For my industrial R&D experience I focused on developing scalable chemical processes for hand off to chemical engineers. My focus was optimizing chemical catalysts. Using a focused R&D lab testing process that minimizes unnecessary work, I figure out how to make catalysts work better, or work at all, creating potential for significant commercial value for clients. Often this has involved investigating feed impurities that cause catalyst deactivation, and study methods of removing impurities that improve catalyst life. I am the inventor or co-inventor on 24 issued U.S. patents and the author or co-author of numerous publications in chemistry journals, so technical writing and editing are strengths, and tasks I enjoy. Some of my recent U.S. patent grants as inventor or co-inventor from process development projects: 11,786,891, “Process for Recovering Quaternary Salt Bromination Catalyst”, October 17, 2023. 10,781,271, "Method for producing brominated and halohydrated polymers", September 22, 2020. 10,604,626, “Process for preparing polycarbamate and reaction product thereof”, March 31, 2020. 10,457,751, "Method for producing brominated and halohydrated polymers" October 29,2019. 10,343,983, “Process to produce polycarbamate, polycarbamate produced thereby and a coating composition comprising the polycarbamate”, July 9, 2019. Some examples of my published papers from optimizing chemical catalysts: “Palladium-Catalyzed Carbonylation of Polychlorinated Pyridines. A Simple Laboratory Approach to Metal Catalyzed Carbonylation Reactions.” Hull, J.W.Jr.; Wang, C. Heterocycles, 2004, Vol 63, page 411. “Extending the Lifetime of a Hydrogenation Catalyst by Removal of Lithium Alkoxide from Styrene-Butadiene Block Copolymers Using Filtration,” Hull, J.W.Jr.; Coppens, K.R.; Hucul, D.A.; Patel, A.M.; Calverley, E.M.; Zoellner, M.J. Macromolecules, 2001, Vol 34, page 8394. “Multigram Preparation of 2-Alkylpyrimidines in the Vapor Phase From Carboxylic Acids and 1,3-Diaminopropane Over a Dual Catalyst System” Hull, J.W.Jr.; Otterson, K. J. Org. Chem. 1992, Vol 57, page 2925. Contact me - I can't wait to begin work on your project! Sincerely, Dr. John H.
