The kettle wax phase in the system sodium laurate, sodium chloride and water
Tóm tắt
A study of the new phase, kettle wax, in the system sodium laurate, sodium chloride and water has been carried out using analytical and visual methods. The lower boundaries of kettle wax and its equilibria were established and when plotted occupy a highly dominant island region on the phase diagram. It occupies a portion between 60 and 70 wt. % soap and about 3 and 7 wt. % of salt. The effects of temperature on kettle wax in this system have also been studied. It was found that kettle wax existed above 75°C. and below 215°C. and has the same type of equilibria with lye throughout this temperature range. In the system sodium laurate, sodium chloride and water, curd is not formed, even by saturating the lye with salt at 90°C. Hence graining out results only in the formation of kettle wax and lye.
