摘要

A new type of oscillating reaction was found from the systematic cesign of the chemical oscillator in water in oil (W/O)emulsions. It is an acidity hydrolysis reaction of long chaintriglyceride in W/O emulsion at 25.0 ± 0. I°C in a bath stirring reactor. During the proeess of reaction, there were periodic and semi-periodic changes lasting more than 10 hoursboth in electrolytic conductivity and electric potential. Microscope also revealed that the emulsion structure changed regularly and puikly. Became of the large differnce in the solubility of the hydrolyzed products, it could be thought, that thediffernt redistribution in the two phases of water and oil induces the regular changes. Marangoni effect of interfacemembrane made oscillation to form. TITne oscillating reactioncan be used to explain the periodic change in the living systemprodrced from coupling between reaction and diffusion.
