Abstract

Abstract: The amount of trace water in poly alpha-olefin (PAO) was measured by Karl Fischer Coulometric Titration method. The detergent turbidity method，the petroleum products color measurement, infrared, and TGA were used respectively to determine the physical and chemical properties of PAO before and after refrigeration. The frozen PAO’s interface phenomenon was analyzed. No influence on the physical and chemical properties of PAO before and after freezing was observed. The results indicate that the trace water is the main reason for the appearance of PAO after freezing.

Key words: PAO, trace water, color , turbidity
