Junior Process Chemistry

Significance of Topic

The optimization of chemical reactions through high-throughput screening and process automation is central to accelerating development in pharmaceuticals, fine chemicals, and materials science. By reducing manual intervention and enabling rapid variation of reaction parameters, research teams can identify optimal conditions more efficiently and with greater confidence.

Objectives and Study Overview

This work introduces and evaluates an integrated platform for reaction screening and process optimization called Junior. The platform aims to streamline reaction setup, enable real-time kinetic analysis, and extend capabilities to high-temperature and high-pressure conditions. Key goals include maximizing throughput, minimizing resource consumption, and facilitating data-driven decision making.

Methodology and Instrumentation

The platform employs automated modules for parallel reaction setup and sampling. Core instrumentation includes:

• Junior automated reactor system with solvent handling, solid and liquid dispensing, stirring, heating, and cooling capabilities
• Optimization Sampling Reactor (OSR) for real-time, time-resolved sampling from multiple pressure- and temperature-controlled vessels without interrupting reactions
• Screening Pressure Reactor (SPR) enabling parallel experiments up to 400 °C and 200 bar
• Additional modules: wash station, vortexing station, multi-position plate rack, and heated multi-tip liquid dispenser
• Software integration through Library Studio for experimental design, Automation Studio for execution, and PolyView for data review and reporting

Main Results and Discussion

The platform supports hundreds of reaction variations per week by allowing simultaneous screening of solvents, ligands, catalysts, reagents, and reaction conditions. Real-time kinetics obtained via the OSR module provide detailed insights into reaction pathways and interaction effects among variables. High-temperature and high-pressure trials conducted in the SPR module demonstrate the system’s robustness under extreme conditions. Integrated analytics and data management ensure seamless linkage between experimental conditions and results, enabling rapid identification of optimal processes.
