Abstract: Effect of precipitator on the stability of blend（crude oil / toluene）has been investigated with Turbiscan Lab
dispersion-stability analyzer. Experiments are performed by mixing varying content of precipitators into the blend（10%by vol.
crude oil and 90%by vol. toluene）. Based on the intensity variation of the transmitted and backscattered light with time，the dynamical
precipitation and aggression process with time can be clearly described and the instability mechanisms of blend（crude
oil / toluene）can be easily studied. In addition，Turbiscan Lab dispersion-stability analyzer can be effectively to quantitatively
analyze the piratical size and aggression and precipitation rate. The results show that both aggression rate and precipitation rate
experienced substantial increased from 192.216 μm/min to 5 332.12 μm/min and from 0.17 μm/min to 0.46 μm/min，Particle
size increases from 10 μm to 53.4 μm，respectively，with percentages of precipitator content going up from 80%to 90.9%.
