Mass transfer rates at liquid–liquid interfaces are relevant for a broad range of processes in natural and technical systems. The objective of this study was to characterize and quantify convective flow along the interface between water and nonaqueous‐phase liquids (NAPLs). Three NAPLs with differen...
