This paper describes phase inversion phenomena in stirred vessels. In particular, the effects of mechanical operating‐parameters on dispersion types were investigated. It was found that when the impeller stirring speed was lower than 400 rpm, the aqueous phase became continuous, while when it was higher than 1050 rpm, the phase which had the higher viscosity became dispersed. Surface active agents have strong effects on phase inversion phenomena.
