SUBSTANCE: invention relates to greasing and emulsifying substances used in fur, leather and other branches of industry. Invention describes a method for deep sulfonation of oxidized vegetable oils, fats and their mixtures, and oxidized mixtures with the nominal viscosity value in the range 33-75 by viscosimeter VZ-4 at 20°C in their treatment with sodium sulfite. The process is carried out in system consisting of oxidized component or mixture of oxidized components, sodium sulfite, water and soap additives, carboxylic acid, phenol and copper (II) salt as a catalyst in bead mill of vertical type at temperature of environment up to practically complete ceasing or quantitative consumption of sodium sulfite and charge of the latter is calculated by the following formula: mNA2SO3 = 0.006 x mOX x (I.N.)OX wherein mOX and (I.N.)OX mean mass and iodine number of oxidized component or mixture of oxidized components, respectively. The mass ratio of oxidized component and water varies in the range from 1:4 to 1:2.5. Dosing additives with respect to oxidized component are following: soap, 2%; carboxylic acid, 4%; phenol, 2.5%. Oxidized flax, sunflower, soybean and cotton oils, oxidized fish oil and mixtures of vegetable oils with fish oil or pig fat are subjected for sulfonation reaction with air in regimen of intensive bubble bubbling at 105 ± 5°. Soaps in indicated system are represented by sodium stearate and sodium oleate and by reaction mixtures of practically quantitative alkaline hydrolysis of fats and vegetable oils also. Benzoic, oxalic, malonic and citric acids are used as acid, and sulfate, acetate and other water-soluble salts of copper (II) are sued as a catalyst dosed in the amount (2-7.5) x 10-4 mole/kg of the parent charge. The sulfonation reaction degree is 33-40%.

EFFECT: improved preparing method.

SUBSTANCE: process is conducted in vertical mill to which soot, induline, kerosene and diesel fuel are introduced. Then components are mixed and slow heating the apparatus and its content is started after which mixing is switched off and slow heating of mill content is continued. Upon expiration of said time, acids or their compositions, white spirit and fatty additive are introduced and chemical mass-exchange process is performed at spontaneously fixed temperature due to thermal effects of this process and natural cooling at the beginning and at the end, as well as due to forced cooling at intermediate stage characterized by high rates of temperature at maximum of 140-150°C. At the moment when forced cooling is discontinued, 0.5-1.5 h before discontinuation of mixing and beginning of withdrawal at temperature of 80-115°C, 43-52-% solution of aluminum salts and C10-C20 of carboxylic acids is introduced into product being prepared.

EFFECT: facilitated procedure; increased amount of product.

SUBSTANCE: preparation of composition is conducted on vertical-type bead mill. Induline, kerosene, and diesel fuel are consecutively charged into mill before stirring mechanism is energized, after which apparatus and contents thereof are slowly heated. Stirring is then stopped for 1 h while slow heating of mill contents is continued. When specified time expires, carboxylic acid or acid mixture, white spirit, fat additive, and aluminum oxide or hydroxide are added. Mechanic stirring is then switched on and contents of the bead mill are ground and the process is carried out at spontaneously fixed temperature caused by heat effects of the processes and natural cooling. When temperature is lowered to 85-120°C, desired product is discharged.

EFFECT: simplified process and increased product discharge degree.
