Big Kahuna Process Chemistry

Importance of the topic

In modern process chemistry, rapid exploration and optimization of reaction conditions are essential for accelerating route development, improving yields and selectivity, and reducing resource consumption. High‐throughput, automated platforms enable systematic screening of multiple variables simultaneously, providing real‐time insights and enhancing decision making in both research and industrial settings.

Objectives and overview of the article

This document presents the capabilities of the Big Kahuna platform by Unchained Labs, designed for micro‐scale, arrayed reaction screening and catalysis optimization. Key goals include: screening discrete and continuous variables, mapping reaction robustness, optimizing catalyst loading, and accelerating new synthetic route development with integrated sampling and analytical workflows.

Methodology and instrumentation

The Big Kahuna system integrates modular tools to automate reagent handling, reaction control, sampling, and work‐up on a micro‐scale array format. Major components include:

• Vial/plate gripper for automated handling
• Waste bin for safe disposal
• Balance with integrated camera for gravimetric dosing
• Photodiode array (PDA) rack for inline UV‐Vis monitoring
• Vortexing station for mixing
• Solid dispensing tool rack for precise powder dosing
• Heating/cooling/stirring station for temperature control
• Capping/decapping station for sealed reactions
• Single‐tip liquid dispenser for low‐volume dosing

Additional modules extend functionality:

• Optimization Sampling Reactor (OSR): eight parallel, pressure‐ and temperature‐controlled vessels with real‐time time‐point sampling for kinetic profiling
• Screening Pressure Reactor (SPR): capability for up to 96 parallel reactions at temperatures up to 400 °C and pressures to 200 bar (3,000 psi)

Main results and discussion

The platform enables simultaneous screening of discrete parameters (e.g., catalyst precursors, ligands) and continuous parameters (temperature, pressure, reaction time), providing detailed reaction profiles. Users can pinpoint optimal conditions for yield and selectivity, map robustness under varied conditions, and identify scale‐up candidates without interrupting reactions. Precise dosing of solids, liquids, slurries, and viscous reagents minimizes consumption of valuable materials and ensures reproducible results across dozens of micro‐scale experiments.

Benefits and practical applications

The Big Kahuna workflow offers:

• Accelerated reaction optimization through parallel screening
• Reduced material use and waste via micro‐scale dosing
• Integrated real‐time analytics for kinetic and endpoint monitoring
• Enhanced data management with linked experimental design and analytical results (Library Studio, Automation Studio, PolyView)
• Flexibility to explore novel synthetic routes, catalyst systems, and process robustness

Future trends and opportunities

Advances are expected in machine learning–guided experiment design, integration of additional in­line spectroscopic and chromatographic analyses, digital twin modeling for predictive optimization, and seamless scale­up workflows that translate micro­scale findings to pilot and manufacturing scale. Further expansion of autonomous decision loops will drive greater efficiency in process development.

Conclusion

The Big Kahuna platform delivers a comprehensive, automated solution for high‐throughput process chemistry. By combining modular hardware, real‐time sampling, and integrated analytics, it empowers chemists to explore diverse reaction spaces efficiently, make data‐driven decisions, and accelerate the journey from discovery to scalable synthesis.
