Oscillations produced from acidity hydrolysis of triglyceride in emulsion

A new type of oscillating reaction was found from the systematic design of the chemical oscillator in water in oil (W/O) emulsions. It Is an acidity h ydrolysis reaction of long chain triglyceride in W/O emulsion at 25.0 +/- 0 .1 degreesC in a bath stirring reactor. During the process of reaction, the re were periodic and semi-periodic changes lasting more than 10 hours both in electrolytic conductivity and electric potential. Microscope also reveal ed that the emulsion structure changed regularly and quickly. Because of th e large difference in the solubility of the hydrolyzed products, it could b e thought, that the different redistribution in the two phases of water and oil induces the regular changes. Marangoni effect of interface membrane ma de oscillation to form. The oscillating reaction can be used to explain the periodic change in the living system produced from coupling between reacti on and diffusion.
