Measurements of the liquid–solid mass transfer coefficient kS were performed in a three‐phase multiple impeller and stationary catalytic basket reactor, called a Robinson–Mahoney reactor. Local coefficients were determined using naphtol particle dissolution in water and n‐heptane with or without gas flow. Experiments have shown that local coefficients kS loc depend on the particle position in the basket, agitation speed, and liquid properties. A correlation linking kS to liquid velocity was established in a reactor simulating hydrodynamics in a piece of catalytic basket. Liquid velocity values were validated using a particle image velocimetry technique in a Robinson–Mahoney reactor, using water. © 2005 American Institute of Chemical Engineers AIChE J, 2005
