Abstract
The study examined the conditions of synthetic low alkaline calcium sulfonate (SLCS) synthesis, which is added to motor oils as a detergent-dispersant additive. In particular, the effect of the introduction of carboxylic acids at the stage of SLCS synthesis on such characteristics of the additive as the observable filterability, volume filtration rate, volume fraction of sediment and kinematic viscosity was studied. For the obtained additive samples the average sizes of particles dispersed in the volume were measured using the dynamic light scattering method (DLS) and the basic physicochemical parameters were determined. Based on the results of studying the microscopic and macroscopic characteristics of SLCS samples, tendencies to improve filterability and product quality indicators, as well as the positive effect of carboxylic acids on the aggregate stability of sulfonate additives, are revealed.
