Electrolytic reduction, catalytic reduction using Ru, Cu-Ba-Cr Raney-Ni, or PtO 2 as a catalyst are used. Products that are easy to handle industrially and have little risk, such as:
NaAlH 2 (OCH 2 ― CH 2 OCH 3 ) 2 , NaAlH
(OC 2 H 5 ) 3 , reduction by Na in alcohol or
Catalytic hydrogenation using Cu--Ba--CrO as a catalyst is preferred. In the laboratory, for example, compound () can be produced in high yield by reacting compound () or its ester with LiAlH4 in an organic solvent such as tetrahydrofuran or dioxane at a temperature from room temperature to reflux. . The compound () of the present invention is a new compound unknown in the literature, and has excellent characteristics as an external base for cosmetics and pharmaceuticals.It can also be used as an intermediate for external bases for other cosmetics and pharmaceuticals, or as a synthetic lubricant. It can also be used as a useful raw material for industrial oils, etc. The raw material carboxylic acid represented by the general formula () is a mixture of 2 moles of methyl ester of radical (・CH 2 (CH 2 ) 4・COOH) generated by treating cyclohexanone with Fuenton's reagent and 1 mole of 2-methylbutadiene. It is obtained by reducing the mixed unsaturated dibasic acid produced in the reaction using a known appropriate method, and as a result of studying its structure, the present inventors deduced it to be a compound represented by the general formula (). Therefore, if the compound of general formula () is reduced, a compound having the structure of general formula () will be obtained. In other words, the compound of general formula () is produced by treating 2 moles of cyclohexanone with Fenton's reagent, and converts 1 mole of 2- into a radical compound.
Carbon number 17 obtained by reacting methyl butadiene
The mixed side chain unsaturated dibasic acid is reduced by a known method to form a mixed side chain saturated dibasic acid with 17 carbon atoms, and further reduced to synthesize a mixed dihydric alcohol with 17 carbon atoms. The substance of the present invention refers to the mixed alcohol obtained here. Therefore, since the above-mentioned reduction reaction is usually carried out as a mixture, the alcohol product produced is a mixture (). Of course, each carboxylic acid as a raw material may be separated by a known appropriate method such as column chromatography, and each may be reduced by the above-mentioned method. Alternatively, the mixed alcohol () may be separated into each alcohol by a known appropriate method such as column chromatography. In fact, from an economical point of view, it is preferable to use it in the form of a mixed alcohol () as a base for cosmetics, pharmaceuticals, etc. To explain in more detail the characteristics of the use of the compounds obtained by the method of the present invention, the compounds obtained by the present invention () are non-irritating to the skin and mucous membranes, and are used in ointments, suppositories, creams, etc. for cosmetics and pharmaceuticals. It is used as a base for emulsions, etc., and is used as a solvent to which drugs and the like are mixed and permeated through the skin. For example, it is non-irritating to the skin, has good affinity, has an excellent texture, and has excellent dissolving ability and permeability to the epidermis, so it is used as a raw material for the oil phase of creams, such as nutritional creams and emollient creams. As an excellent dermatological vehicle for drugs, it is ideal for medicinal creams, etc. Other powder products, skin protectants, make-up creams and lipstick products, used as superfat agents to prevent cosmetics from crumbling, and lipstick pigments.When used in place of mineral oil, the emulsification stabilizes, making hair soft and shiny. Hair oil and hair cream products because of their excellent lubricity, pine surge oil because of their excellent lubricity, pine surge products that are creams, hand cream products because they are very smooth and non-sticky to the skin, and excellent skin affinity and chemical stability. Due to its unique properties, it is useful in a wide range of pharmaceutical applications, such as being used as an oil component in ointments, especially in eye ointments and suppository products. Furthermore, the present compounds are stable to heat and light, and do not easily decompose even at temperatures of, for example, 150°C. This compound is generally sparingly soluble in water and soluble in organic solvents such as alcohols, chloroform, acetone, and ether. This substance has a high boiling point and flash point, and is a stable compound without being oxidized even when left in the air for a long time. Since the compound obtained by the present invention has not been described in any literature, the proof was made using an infrared absorption spectrum. That is, in the infrared absorption spectrum, the absorption of carboxyl groups disappears and a new strong absorption corresponding to hydroxyl groups is observed around 3300 cm -1 , which confirms the production of this compound. The method of the present invention will be explained below with reference to Examples, but it is not limited thereto. Note that Reference Example-1 shows the raw material compound of (), and Reference Example-2 shows a production example of compound (). Reference example 1 Dissolve 70g of isoprene (2-methyl-1,3-butadiene) in 300ml of methanol, add 80g of cyclohexanone, 80g of 35% hydrogen peroxide and
After adding 3.5 g of 98% sulfuric acid and stirring at 20±5°C for 0.5 hour, 250 g of ferrous sulfate (heptahydrate) was gradually added while maintaining the temperature at 0 to -5°C. After reaction, 60%
After adding 18 g of sulfuric acid and stirring, the mixture was allowed to stand until it separated into two layers. The upper layer was separated, washed with dilute sulfuric acid and water, and dried to obtain a compound with the following structure () () as an oily substance.

This is the structure obtained by estimation. Regarding the ratio, when the reaction was carried out more than 10 times under the same conditions as in the reference example above, and the resulting product was analyzed by gas chromatography, the same results as above were obtained, and the ratio was as follows. Ta. Dimethyl ester of compound () Approx. 76-82% Dimethyl ester of compound () Approx. 15-19% Dimethyl ester of compound () Approx. 2.5-6% Dimethyl ester of compound (), () and () obtained above The mixture was hydrolyzed in a dilute aqueous sodium hydroxide solution under heating according to a conventional method to obtain compounds (), () and (). It was confirmed by gas chromatography similar to the above that the mixing ratio of these compounds (), (), and () did not change due to hydrolysis. Reference example 2 Production method of mixed dibasic acid with 17 carbon atoms () Unsaturated side chain dibasic acid (), () and ()
Dissolve 50g of the mixture in 500ml acetic acid to give 5% pd/c2
After catalytic hydrogenation for about 12 hours at 60°C and 5 atmospheres of hydrogen using g as a catalyst, the catalyst was filtered off and the filtrate was concentrated under reduced pressure, washed with hot water, dehydrated and mixed with saturated side chains of the target product. 47 g of dibasic acid (2) was obtained as a colorless and transparent oil. Acid value 372, saponification value 374, iodine value 1.2. The mixing ratio of the three types of dibasic acids in the obtained oil was the same as in the compounds (), () and () obtained in the above reference example. Furthermore, the presence of a double bond is ruled out based on the iodine value, and it is certain that the structure is the one of the general formula () that has undergone catalytic reduction. In addition, in the infrared absorption spectrum, an absorption characteristic of carboxylic acid is clearly observed at 1730 to 1740 cm -1 . Example 1 Method for producing mixed dihydric alcohol with 17 carbon atoms () 3 g of a mixture of dibasic acids with mixed side chains () was dissolved in 20 ml of methanol, 1 drop of concentrated sulfuric acid was added thereto, and the mixture was refluxed for 5 to 6 hours. let Neutralize with dilute Na 2 CO 3 water, distill off methanol, and extract with ether.
