The object of research is the reaction of phenol sulfomethylation in an aqueous medium, with the aim of obtaining water-soluble non-toxic products based on it used as surfactants. One of the most problematic places is the need to maintain the stability of the system and the content of a given pH with the introduction of the sulfonate agent: the reaction temperature is 125–130 °C, the polycondensation time is 8 hours, the reaction takes place under pressure. This method produces a reaction product that is a fairly complex mixture of monomers, dimers, trimmers and free phenol. Also, during the reaction of phenol sulfomethylation in an aqueous medium, the reaction mass is formed, which is a two-phase system: the upper organic layer is phenols, the lower layer is an aqueous solution of the formaldehyde bisulfite derivative. Significant disadvantage of this method is the relatively low yield of the target product and the high temperature of the reaction. In the course of the research, the reaction of phenol sulfomethylation under micellar catalysis is studied. The optimal amount of starting materials and the amount of phase transfer catalyst are determined. The use of these catalysts makes it possible to improve the main technological parameters: reduce the reaction temperature from 125–130 °C to 75–80 °C, shorten the process time to 1 hour, carry out the process at atmospheric pressure. The advantage of this technology is also non-waste, single-stage production and is available to Ukrainian raw materials. During the study, a product is obtained that has properties characteristic for surfactant: with increasing molecular weight, the surface tension of aqueous solutions increases and leads to a decrease in surface activity. Thus, according to the results of studies of the technological characteristics of the obtained samples of surfactants, they can be used as anion-active surfactants, used as stabilizers in the production of organic dyes, textile auxiliaries and as plasticizers for concrete.
