Effect of stirrer type and material system

Fischer [125] compared the suitability of a -paddle stirrer with vertical (free and also partly covered on both sides) and pitched paddles with a rotating disc for use in an agitated extraction columns (type Ktihni) and found, that the disc was not suitable for dispersion, whereas the three paddle stirrer arrangements were comparable in performance. [Pg.255]

Judat [244] investigated the dispersion action of rapidly rotating stirrer types 3-vane propeller stirrer, 6-pitched-blade stirrer (a = 45°), 6-blade turbine stirrer and a rotor-stator arrangement (rotor 6-turbine stirrer, stator 24 vertical paddles whose angle could be varied between —60° and +60° with respect to the radial position). [Pg.255]

Isobutyl chloride/water and cyclohexane/water ( = 0 02) were used, see Table [Pg.255]

The stirrer power per unit volume was maintained constant with P/V = 0.5 or 1.0 kW/m After 30 minutes stirring the samples were fixed by interfacial polycondensation with a diamine. [Pg.255]

The test evaluation was undertaken in the pi-space B (Section 6.2.4) and represented in the form of a log-log normal distribution. The curves obtained were to a [Pg.255]
