Description

The invention relates to methods for the preparation of emulsions, namely, soluble oils or emulsols, and can be used in oil-producing, oil-refining, food, cosmetic and other industrial industries. A known method of obtaining emulsions with simultaneous carrying out of a chemical reaction at the interface between the chemical mixing of an oil solution of the corresponding fatty acid and an aqueous solution of alkali 1. The disadvantage of this method is the greater energy intensity of the process, the use of large amounts of alkali, the dependence of process from the physicochemical properties of the hydrocarbon phase (to obtain gasoline-water emulsions, kerosene is not feasible). H; the closest to the technical, essence and the achieved result to the proposed is a method of obtaining soluble oils or emulsion of solov, including mechanical mixing of the hydrocarbon phase with water, when this is introduced from 10 to the hydrocarbon phase. 40% strongly surfactant acidic sodium. The disadvantage of this method is its dependence on the physicochemical PROPERTIES of the hydrocarbon phase, the high energy intensity of the process, the use of a quantitative (a) (up to 40%) surfactant and its high cost. The purpose of the invention is to obtain stable, water-soluble systems that do not depend on the physicochemical properties of the hydrocarbon phase, and to reduce the cost of the process by reducing its energy intensity and reducing the costs of surfactants. This goal is achieved by subjecting the hydrocarbon phase, surfactants, for example, soluble salts of silicic acid and water, to mechanical stirring for 3-5 minutes, after which rosin is added and the resulting mixture is stirred until a gel-structured system is formed. components are used in the following ratio, -weighted.%. Hydrocarbon phase 70-90 Surfactants Oi1-0 5 Rosin 0.1-0.5 Water Else The distinctive features of the proposed method is that mechanical mixing of the starting components is carried out for 3-5 minutes, after which rosin is added and the resulting mixture mix to form a gel-structured system, with the initial components used in the above ratio. Another difference is that soluble silicate salts are taken as surfactants. According to the proposed method, mechanical mixing at the first stage of the hydrocarbon phase of the surfactant and water provides an increase in the oil-in-water interface and, in the second stage, mixing intensifies the rate of interaction of rosin with the mixture. The addition of rosin to the resulting mass in the presence of a silicic acid salt as a -SAV provides a means between the hydrocarbon phase and, through the possibility of using the externally applied mechanical energy as the main energy source, contributing to the manifestation of the mechanical-chemical and catalytic effects associated with the violation of molecules structures of the interacting phases, and, as a result, the manifestation of various kinds of physicochemical interactions that provide, regardless of physical and chemical properties of the hydrocarbon phase, obtaining stable, gel-structured, water-soluble systems. The starting components in the proposed method are readily available and inexpensive and are produced by the domestic industry in sufficient quantities. The salt of silicic acid NajSfO is produced in the form of lumps and powder (hard and easily soluble) and in the form of a liquid of different strength {36-40 B-or-dinary, 50-58 ° and 70 ° B-double). Rosin is a product of the distillation of sap or sulfur resin produced by artificially injuring the bark of coniferous trees. Turpentine is used in the distillation of the resin with steam, and the solid residue after purification is rosin. |. As a hydrocarbon phase, oils selected from various fields, as well as petroleum products (gasoline, kerosene, oils АС-8, АС-10, etc.) are used. Example. The emulsifier cylinder is filled with a mixture consisting of the hydrocarbon phase, silicic acid salt and water, and the mixing process is carried out for 3-5 minutes. After the indicated time has elapsed, the mixing process is stopped and rosin is added to the mixture, after which the mixing process is resumed until a gel-structuring system is obtained. The whole process takes 10-15 minutes. To determine the choice of boundary and average values of the initial components, three mixtures are prepared, each containing a hydrocarbon phase (gasoline or oil AC-8) —70 wt% and differing from each other in the content of silicic acid salt (water glass), respectively, wt%; 0.1; 0.3; 0.5, the rest is water, respectively, up to wt.% 99.9; 99.7; 99.5.

The mixture is stirred for 35 minutes, then rosin is added to each mixture, respectively / wt%; 0.1; 0.3; 0.5 (i.e., respectively, up to wt.%: 100) and the blending process is renewed to obtain a gel-structured system. Three mixtures are prepared containing each hydrocarbon phase (gasoline or AC-8 oil) —90 wt.%, Differing from each other in the content of silicic acid salt (water glass), respectively, wt.%: 0.1; 0.3; 0.5, the rest is water, respectively, up to wt.%: 99.9; 99.7; 99.5. The mixture is stirred for 35 minutes, then rosin is added to each mixture, respectively, wt.%: 0.1; 0.3; 0.5 (i.e., respectively, up to, wt.%: 100), and the mixing process is resumed to obtain a gel-structured system. In addition, they investigate mixtures that differ from each other by the content of rosin and water, all other conditions being equal. For this, three mixtures are prepared, each containing a hydrocarbon phase (gasoline or oil AC-8) —70% by weight and a salt of silicic acid (water glass) — 0.3% by weight, differing from each other in water content, respectively, weight %: 29.2; 29.4; 29.6.

Table continuation

A decrease in the salt of silicic acid and rosin, less than 0.1 wt.%, Has a negative effect on the process, since it becomes impossible to carry out the process to the end, because about 20% of the initial hydrocarbon phase does not react and is free. % of the remaining mass Acquires high structural and mechanical properties, which makes further mixing of the system difficult.

Reducing the water content to less than 9.8 wt.% Dramatically complicates the mixing process, and the increase is greater. 30 wt.% Leads to the disappearance of the structural-mechanical properties of the resulting emulsions,

The proposed method is economically feasible, since, apart from the absence of restrictions on the choice of the hydrocarbon phase and the reduction of the energy intensity of the process, it provides a drastic reduction in the use of surfactant BeiqecTBa. The economic effect from the implementation of the proposed method, only by reducing the consumption of surfactants per 1000 tons of finished products will amount to 236 thousand rubles / year.
