“…Indeed in this test, the phenomenon of methanol drawdown in oil was practically instantaneous, and the influence of interfacial mass-transfer was considered very small, on the basis of the analysis illustrated in section 3.1; the observed initial reaction rate was therefore assumed to be an acceptable approximation of the actual rate of chemical reaction. The evaluation of the parameters and mass-transfer coefficients contained in the expressions of t T,NP , t T,P and t D,P , derived from refs − , is illustrated in the Supporting Information. The Sauter mean diameter ( d 32 ) relative to each configuration at the beginning of the reaction test was estimated on the basis of eq , thus neglecting the evolution of d 32 from the initial value to the stationary value provided by eq . ,,, This choice implies an underestimate of the mass-transfer resistance during the initial part of the reaction.…”
