である。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an addition reaction between a hydroxyaryl compound and an unsaturated fatty acid, and specifically relates to a method for producing a hydroxyaryl fatty acid using activated clay as a catalyst. .
不飽和脂肪酸類にフェノール、クレゾール、アニソール
などのヒドロキシアリール化合物を付加反応させて得ら
れるヒドロキシアリール脂肪酸類は、抗酸化剤、腐食防
止剤、防錆剤などとして広く利用されている。Hydroxyaryl fatty acids obtained by addition-reacting unsaturated fatty acids with hydroxyaryl compounds such as phenol, cresol, and anisole are widely used as antioxidants, corrosion inhibitors, rust preventives, and the like.

換樹脂の場合、付加反応の収率が低いといった難点があ
った。Conventionally, in addition reactions between hydroxyaryl compounds and unsaturated fatty acids to obtain such hydroxyaryl fatty acids, acid catalysts such as aluminum chloride, sulfuric acid, methanesulfonic acid, and strongly acidic ion exchange resins have been used as catalysts. has been used. However, in the case of the first three, it is difficult to separate the catalyst, cause corrosion of the equipment, and side reactions are likely to occur; - In the case of strongly acidic ion exchange resins, the yield of addition reaction is low. The problem was that it was low.
そこで、これらの触媒に代えて、活性白土を用いること

の面で良好な結果が得られている。Therefore, it has been proposed to use activated clay in place of these catalysts (Special Publication No. 6581-1971, Japanese Patent Publication No. 41-6581,
No. 9-20304, Japanese Patent Publication No. 50-5704, Japanese Patent Publication No. 1983
1-53240, Japanese Unexamined Patent Publication No. 62-10040, etc.), by using this activated clay, it is possible to improve the separation of the catalyst described above, prevention of equipment corrosion and side reactions, and improvement of yield. results have been obtained.

着色するという問題があった。However, activated clay used as a catalyst has a weak acid strength compared to other catalysts, so it is necessary to raise the temperature to a high temperature of 150° C. or higher during the addition reaction. For this reason, there is a problem that the produced hydroxyaryl fatty acids have a dark hue, or even if they are pale, the hue is unstable and becomes colored over time.

安定なヒドロキシアリール脂肪酸類を上記方法により製
造することを目的としている。Therefore, the present invention solves the above-mentioned problems in the method of using activated clay as an addition reaction catalyst between a hydroxyaryl compound and an unsaturated fatty acid, and produces a light-colored and stable hydroxyaryl fatty acid by the above-mentioned method. The purpose is to

られるヒドロキシアリール脂肪酸類はその色相および色
相安定性がヒドロキシアリール脂肪酸類中に含まれる鉄
分の量に依存するものであることを知った。In the process of intensive study to achieve the above object, the inventors first discovered that the hue and hue stability of hydroxyaryl fatty acids obtained using activated clay as a catalyst were higher than that of hydroxyaryl fatty acids. I learned that it depends on the amount of iron in the body.

のとなることを見い出した。Therefore, as a result of further investigation based on this knowledge, after producing hydroxyaryl fatty acids using activated clay, a certain chemical substance was added to the reaction solution, and activated clay was added to the reaction solution. It has been found that by removing , the amount of iron contained in the resulting hydroxyaryl fatty acids is reduced, and the hue and hue stability are significantly improved.

性白土を後の工程で分離除去したのちに、留去される。In this invention, first, as a first step, a hydroxyaryl compound and an unsaturated fatty acid are reacted using activated clay as a catalyst. This reaction may be carried out according to a known method, for example, by heating in an autoclave to 125 to 225°C, preferably 160 to 200°C. At that time, it is usually desirable to use the hydroxyaryl compound in excess of the unsaturated fatty acid to complete the reaction. Excess hydroxyaryl compound is distilled off after the activated clay serving as a post-reaction catalyst is separated and removed in a later step.

好適な添加量は、００１〜１重量％の範囲である。The amount of EDTA or its salt added is usually 0.05% by weight or more based on the produced hydroxyaryl fatty acids. If this amount is too small, the iron content in the hydroxyaryl fatty acids may be reduced in color. Moreover, it is not possible to reduce the amount to a value suitable for improving hue stability, for example, 5 ppm or less, making it difficult to achieve the intended purpose. The upper limit of the amount added is usually 2% by weight, and adding more than this will not change the effect and is economically disadvantageous. A particularly suitable addition amount is in the range of 0.001 to 1% by weight.
