N2 - Recent work has shown that heating degassed oil-in-water emulsions causes a significant reduction in the oil droplet size. The results presented here report further work on the effect of changes in salt concentration, oil/water ratio, pH and heating, on the oil droplet sizes of dispersions produced by the de-gassing process. The change in particle or droplet size for long, straight chain hydrocarbon oils, dispersed in water by degassing, is also reported here. These oils, of 20-24 carbon units in length, are liquid when heated above 50 °C but are solid at room temperature. The particle size of these dispersions was also monitored during the phase transition from liquid to solid, on cooling.
