2. Description of the Related Art As waxes extracted from plants, there are carnauba wax, candelilla wax, rice bran wax, sugarken wax and the like, and purification treatments such as decolorization and deodorization have been performed for commercialization. Since these are natural products, they contain a large amount of esters, hydrocarbons, free long-chain fatty acids, free long-chain alcohols, and resin components. Among them, the long-chain fatty acid and the resin component have different physical behaviors from other components and cause various problems in expanding the range of application of such wax, so it is necessary to remove them. There is no industrially-known example of purification treatment that changes the composition of components.

For example, carnauba wax is Copernicia
cerifera Martius is a plant wax obtained from the leaves of a plant of the family Palmaceae, has a high melting point of about 80 to 86 ° C, contains a hydroxyl acid ester, and has excellent emulsifying properties. Therefore, it has many uses such as cosmetics, polishes, carbon inks, leather finishing, precision casting, pharmaceuticals, polishes and paints. Usually, carnauba wax has a different composition depending on the part of the palm leaf to be obtained, and the so-called No. 1 wax contains an ester content of 80 to 85%, and other components include free alcohol and fatty acid and about 3 to 4 % Resin content. However, as the quality of the wax decreases, the ester content decreases and the color tone also deteriorates.

In particular, the resin content of No. 2 wax and No. 3 wax increases to about 20 to 40%, and there are problems such as clogging during handling and poor solubility in ethanol. Japanese Patent Laid-Open Publication No. 9-34242 discusses the removal method. Further, the free fatty acid causes a phenomenon of bleeding on the surface of the wax (bleeding), which causes quality deterioration of various products and deterioration of commercial value in appearance. This bleeding occurs remarkably when the acid value of the wax is about 10 or more. Conventionally, as a deoxidizing method for solid fats, an esterification method (JP-A-2-115300)
Also known is a method of making alkaline soap in an organic solvent and washing with water. For example, rice bran wax is obtained by cooling and depositing rice bran oil, and the deoxidation of rice bran wax is also performed at the same time by alkaline deoxidizing a hexane solution of crude rice bran oil.

However, although the above-mentioned esterification method is convenient as an operation method, it is difficult to use it for food use because it is a synthetic product. Further, although an organic acid is used for preventing coloration, it tends to be colored by heating, which causes a problem in terms of color tone. Further, in the method of washing with alkaline soap and rinsing with water, the solution is emulsified in an actual operation and it is difficult to separate the soap from the wax. Therefore, an object of the present invention is to provide a method that is simple in operation and simultaneously performs deoxidation of crude wax extracted from plants, improvement of color tone, and removal of resin components without causing quality deterioration due to coloring. is there.

That is, according to the present invention, a crude wax extracted from a plant is melted, a divalent metal compound is allowed to act on the free fatty acid in the wax, and a polar solvent is added to the wax to add 75 to the free fatty acid.
It is a method for purifying a vegetable wax, which comprises heating to -100 ° C and extracting the wax component with a polar solvent. Monovalent metal soap such as sodium soap has good solubility in a polar solvent and is not suitable for separation from wax. Further, metal soaps having a valence of 3 or more, such as aluminum soaps, are not suitable because they gelate the polar solvent. Alkaline earth metals are preferable as the divalent metal, and calcium and / or magnesium are particularly preferable. That is, in order to produce a metallic soap, vegetable wax is melted, calcium and / or
Alternatively, a metal powder of magnesium, an oxide, a hydroxide, a carbonate or the like is allowed to act. These may be used alone or as a mixture. Oxides and carbonates are particularly preferable. The addition amount is appropriately 1 to 20 times the theoretical amount calculated from the acid value of the plant wax to be treated. Further, in order to promote the soaping reaction, coexistence of water, dibasic acid, hydrogen peroxide, surfactant, polyhydric alcohol, aluminosilicate, alkali metal ion and the like is effective.

In addition, the free fatty acid in the vegetable wax is once neutralized with an alkali metal hydroxide such as sodium and then reacted with an alkaline earth metal chloride or sulfate in an aqueous solution to obtain the desired metal. There is a way to get soap.
In the case of this method, in order to increase the solubility of the wax in the polar solvent, it is necessary to sufficiently dehydrate the reaction liquid before the extraction operation. Next, a polar solvent is added to the vegetable wax containing the divalent metal soap obtained by the above operation, and the temperature is 75 ° C to 100 ° C.
To dissolve the wax. At this time, the insoluble resin component and the divalent metal soap are deposited as a paste-like precipitate, and the excess unreacted metal or unreacted metal compound is precipitated as a solid at the bottom of the solvent. After the precipitate and the supernatant liquid are allowed to stand still and separated while being heated to such a temperature, a supernatant liquid is obtained by an operation such as decantation, and the solvent is further removed by distillation, crystallization, filtration treatment or the like. The purified vegetable wax of The purified vegetable wax thus obtained is decolorized as well as being reduced in acid value. Examples of the polar solvent used in the present invention include lower alcohols such as methanol, ethanol, butanol, propanol, and isopropanol, and acetone and methyl ethyl ketone. Ethanol or isopropanol is preferable from the viewpoint of boiling point and solubility. Examples are shown below, but these do not limit the embodiments of the present invention.
