A process for the treatment of acidic tars by reacting with ethoxylated products and subsequent neutralization, characterized in that, in order to increase the efficiency of the process by reducing the content of sulfuric acid while increasing its degree of use, the original product is mixed with ethoxylated alkylphenols and telodetedeteadloxide-tee; -30 min at 45-60 ° C, followed by treatment of the mixture at the same temperature with a fraction of dioxane alcohols produced by isopr using the dioxane method and stirring for 45-60 min, the process is carried out at a mass ratio of acid tar, phosphate petoxide (L fora, ethoxylated alkylphenols, dioxane alcohols, equal to 1: (O, 03-0.06) :( O, 33-0.56): |
