Abstrakt: This paper discusses the unprecedented microscopic findings of micellar growth in colloidal system (CS) of catalyzed piperidinolysis of ionized phenyl salicylate (PS - ). The giant vesicles (GV) was observed under the optical polarization microscope (OPM) at [NaX]=0.1M where X=3-isopropC 6 H 4 O - . The conditions were rationalized from pseudo-first-order rate constant, k obs of PS - of micellar phase at 31.1×10 -3 s -1 reported in previous publication. The overall diameter of GV (57.6μm) in CS (CTABr/NaX/H 2 O)-catalyzed piperidinolysis (where X=3-isopropC 6 H 4 O) of ionized phenyl salicylate were found as giant unilamellar vesicles (GUV) and giant multilamellar vesicles (GMV). The findings were also validated by means of rheological analysis.
