    A method of recovering a high-grade lecithin and solvents from an oil-bearing full miscella which also contains _lecithin and which results from an oilseed ternary solvent extraction process. The method may include a first step of phase separation of the oil-bearing miscella containing lecithin and the ternary solvents into a polar and non-polar phase, and a second step of azeotropic distillation of the non-polar phase to recover a portion of the solvents, and to remove substantially all the water from the residual crude oil, thereby keeping the lecithin in solution. A commercial grade lecithin having good water dispersibility may subsequently be recovered from the residual crude oil, and a small amount of highly water dispersible lecithin may be recovered from the polar phase by atmospheric distillation. In another embodiment, when the full miscella containing crude oil ternary solvent and lecithin resulting from the above ternary solvent extraction is initially subjected to azeotropic distillation to recover solvent therefrom and remove substantially all the water, a highly water dispersible lecithin having a high choline chloride content is obtained. Premature degumming of this highly water dispersible lecithin is avoided by maintaining the solvent ratios above certain minimums. The ternary solvents for the oilseed extraction include a lipophilic hydrocarbon, such as hexane: a water miscible lower alcohol, such as ethanol; and a minor amount of water. The recovery method is energy efficient, because the boiling temperature of the ternary azeotrope is lower than any other combination of the three solvents.

    11 The invention is intended for use in the oil and fat industry and relates to methods for producing oil and phosphatides from soybean seeds. When extracting oil from soybean seeds using a three-component solvent, one of the difficulties is to remove the solvent from the micelle, because it contains water, converting to oil and causing premature precipitation of phosphatides and increasing their viscosity. This adversely affects the movement of oil through pipelines. Methods are known that use azeotropic systems as a three-component solvent and remove the solvent from the micelle by azeotropic distillation at different temperatures flj and C2: .. The closest to the proposed technical essence and the achieved result is the method of obtaining oil and phosphatides from seeds. in soybeans by extraction with a three-component solvent consisting of hexane, ethanol and water, to obtain a micelle, removing the solvent from the micelle by azeotropic distillation and subsequent extraction of phosphatides from oil by CJ. However, in the known methods, the ratio of solvent components was not developed, making possible a clear removal of the solvent, and the solvent was removed from the whole micelle. The advantages of azeotropic distillation were thus not used. The task of preserving the phosphatides in the oil in this method is also not solved. The aim of the invention is to facilitate the removal of the solvent, preventing spontaneous precipitation. phosphatides oil and improving the quality of the latter. The goal is achieved by those. According to the method for producing oil and phosphatides from soybean seeds by extraction with a three-component solvent consisting of hexane, ethanol and water, to obtain a micelle, removing the solvent from the micelle by azeotropic distillation and subsequent separation of the phosphatides from the oil, the solvent components are chosen at least 7.1: 1 for hexane and ethanol and 4: 1 for ethanol and water, and azeotropic distillation is carried out in three stages, the first of which remove water, the second ethanol, and the third hexane. The three-component solvent is an azeotropic system, including the oleophilic component — hexane, the lower alcohol — ethanol, and water, which can be introduced into the system separately or as moisture of the seed itself, provided that its content is accurately taken into account. The ratios of the components are selected so that there is an excess of hexane over ethanol and alcohol over water, sufficient so that when the micelle is heated to azeotropic distillation temperature, all the water is removed first, then the alcohol. Alcohol can be added to the desired ratio or water. It is the ratio of hexane: ethanol, equal to 7.1: 1, and the ratio of ethanol: water, equal to at least k: facilitates azeotropic distillation with the lowest energy consumption, and the removal of water at the first stage of distillation prevents the spontaneous hydration of oil under the action water and precipitation of phosphatides dispersed in oil. The method is carried out as follows. Soybean seeds, prepared by conventional methods, are treated with a three-component solvent and receive micelle containing crude oil and phosphatides. You can optionally add alcohol or water to maintain the above ratios of the components in the micelle. Then, the distillation of the micelle with a film evaporator or other equipment is started, which ensures its heating to the evaporation temperature of the solvent. For the hexane: ethanol: water system, this temperature at atmospheric pressure is 5b C. As a result of the distillation before the temperature of the vapor phase changes from 5b C, water is completely removed from the micelles, which can be condensed and reused. After the first distillation stage, the evaporation temperature of the remaining hexane: alcohol mixture is changed to 58.70 and distillation
