The purpose of this article is to study the composition of feedstock and products of the process of production of linear alkylbenzene sulfonic acid as a main component of synthetic detergents. Light aromatic compounds, contained in sulfonation feedstock, form a highly viscous component as a result of dealkylation and polymerization reactions. This component is able to accumulate in the sulfonation reactor reducing efficiency and uniformity of the process and the duration of period between reactor washings.
