1. A method for producing sodium salt of oil sulfate sulphate, characterized in that the prepolymerized fraction 200-400 of catalytic cracking or pyrolysis of crude oil at 60-180 s in the presence of an acid catalyst is subjected to sulfonation with 100-102% sulfuric acid at a weight ratio of 1.84-5: 1, respectively, at 40-120 ° C for 1.5-4 hours, followed by condensation of sulfonase with an aqueous solution of formaldehyde at a weight ratio of 8.6-11: 1, respectively at 95-100 s for 5-6 h and neutral the condensation of the resulting condensate sodium hydroxide 2. The method according to Claim 1, is also distinguished with R in that sulfuric acid or toluenesulfonic acid, f / 1 or an industrial aluminosilicate catalyst is used as the acid catalyst. |
