ABSTRACT:
Process for the determination of the turbidity point of a liquid, which consists in progressively cooling the liquid and noting the temperature at which turbidity appears; the temperatures at the center (T.sub.1) and at the periphery (T.sub.2) of the liquid are measured, their graphs as a function of time (.theta.) are plotted and changes in the slope of these graphs are noted, the turbidity point being the temperature (T.sub.1) at the center of the liquid which corresponds to the change in slope on the graph T.sub.2 -.function.'(.theta.).
