Abstract

Heat is intrinsic to mechanochemistry, and temperature is known to play a key role in the kinetics of many reactions. Here, we introduce a technique to accurately quantify temperatures within mechanochemical processes. Treating these processes as a thermodynamic system, we reveal the highly sensitive effects that reaction vessel, internal conditions, and environmental parameters can have on heat flow and temperature within the reaction space. We show how this also determines space-and time-resolved metrology limits when measuring temperature changes using single-point or full-field infrared thermography approaches. After identifying these fundamental limits, we present an accessible in situ thermography approach to directly obtain batch temperature accurately, nonintrusively, and in real-time.
