Crystal violet was recovered from aq. 2-5 mg/l. solns. by cloud-p. extn. with oxyethylenated(n =9) methyl dodecanoate as nonionic and cocamidopropyl betaine as zwitterionic surfactant. The dye was recovered (2500 rpm) in 92.1%. from the system contg. dodecanoate 2.5, betaine 0.5% and NaCl 1 mol/l.; heating time 6 hrs, The formation of the dye-contg. surfactant phase was incomplete. The water phase contained surfactant-rich agglomerates. NaCl reduced the time of formation and the size of the sepg. agglomerates. In solns. contg. the two surfactants, betaine concn. (should not exceed 0.5%) controlled the cloud p. In aq. 01-5% betaine soins., no cloud p. occurred over 0-100 degrees C.
