Resumo

The effect of an inhibitory composition based on an amphiphilic polymer of polyacrylate and stearic acid on the composition of paraffinic hydrocarbons in asphalt-resin-paraffin deposits (ARPD) of high-paraffin oil was studied. It is shown that with the addition of an amphiphilic polymer and a composition to oil, differences are observed in the nature of their molecular mass distribution of paraffinic hydrocarbons of the surfactants. The action of the polymer leads to a decrease in the content of hydrocarbons of the composition C16–C21 and an increase in the proportion of high-molecular hydrocarbons C22–C34. The use of stearic acid as a surfactant in the composition, on the contrary, reduces the amount of high molecular weight paraffin hydrocarbons.
