PERFORMING THE CALCULATIONS ON LAB SULFONATION PARAMETERS USING THE MATHEMATICAL MODEL.

The continuous growth of demand on synthetic detergents worldwide, which include such components as surfactants causes increasing of research and optimization interests towards the process of obtaining linear alkylbenzenes or the problem of linear alkylbenzenes sulfonation. The method of mathematical modelling used in this paper was chosen as the best concerning the optimization of the process. It allows monitoring the influence of main parameters without interfering in the process. As the result mathematical model of linear alkylbenzenes (LAB) sulfonation process was obtained. Adequacy of which is supported by the correspondence of calculated and experimental dependencies of the main parameters (such as yields of target and some side products, which are alkylbenzene sulfonic acid (ASA) and, for example, highly viscous component respectively). Also, information about the dependency of highly viscous component accumulation and ASA from temperature and film thickness in the reactor is obtained. [ABSTRACT FROM AUTHOR]
