Description

本発明は、新規リン酸化物に関し、詳細には、環状のリン酸基及びエステル結合を分子中に含有する環状リン酸化物に関する。   The present invention relates to a novel phosphorous oxide, and more particularly to a cyclic phosphoric oxide containing a cyclic phosphate group and an ester bond in the molecule.

天然由来のレシチン(ホスファチジルコリン)に代表される2鎖1親水基含有界面活性剤は、疎水基が一つの1鎖1親水基含有界面活性剤に比べ、一分子中に2個の疎水基を有するため一般的に水への溶解性が低く、単分散しにくいとされている。しかしながら、濃度が分散の飽和値に達すると、水中で分子が規則正しく配列した会合体であるミセルを形成し、水中に均一に分散することが知られている。特に炭素数12〜20のものは、水中で板状の二分子膜を形成して分散し、この分散液に、強いせん断力を加えると二分子膜が閉じたベシクルと呼ばれる小包を形成するなどの特長を有する。2鎖1親水基含有界面活性剤、特にレシチンについては、その用途は、食品工業、一般工業、飼料、医薬品等各方面に幅広く利用されている。また、その優れた界面活性能のために低濃度の配合で済み、環境への負荷が軽減化され、皮膚刺激もほとんどないなどの特徴から、各分野で研究開発が進められており、リン脂質の脂肪酸をエステル交換する等の種々の改質がなされている(特許文献1、2)。   2 chain 1 hydrophilic group-containing surfactants typified by naturally derived lecithin (phosphatidylcholine) have 2 hydrophobic groups in one molecule as compared to 1 chain 1 hydrophilic group-containing surfactant. Therefore, it is generally considered that the solubility in water is low and monodispersion is difficult. However, it is known that when the concentration reaches the saturation value of dispersion, micelles, which are aggregates in which molecules are regularly arranged in water, are formed and dispersed uniformly in water. In particular, those having 12 to 20 carbon atoms are dispersed by forming a plate-like bilayer membrane in water, and when a strong shearing force is applied to this dispersion, a bilayer-closed vesicle called a vesicle is formed. It has the following features. As for the surfactant containing 2 chain 1 hydrophilic group, particularly lecithin, its use is widely used in various fields such as food industry, general industry, feed and pharmaceuticals. In addition, because of its excellent surface activity, it requires only a low concentration, reduces the environmental burden, and has almost no skin irritation. Various modifications have been made such as transesterification of the fatty acid (Patent Documents 1 and 2).

2鎖1親水基含有界面活性剤は、2分子の連結や、疎水基、極性基の導入が必ずしも容易ではないため、分子設計が限定されたものにならざるを得ず、しかもその中で比較的高価な原材料の使用を余儀なくされることが多いという問題があり、特許文献1、2の方法のように酵素によるエステル交換を行う方法も、エステル交換される基の選択性に乏しく、目的とする構造の化合物を高純度で得ることが困難であった。このため2鎖1親水基含有界面活性剤は、その優れた性能にもかかわらず、実用化には大きな問題を有しているのが実情である。本発明者等は、かかる課題を解決すべく鋭意研究した結果、不飽和脂肪酸のアルキルエステルの二重結合部分に環状のリン酸基を導入した環状リン酸化物が、安価な原材料のみを用いて容易に生産でき、2鎖1親水基含有界面活性剤としての利用や、他の2鎖1親水基含有界面活性剤の合成に有用であることを見出し、本発明を完成するに至った。   In the case of surfactants containing 2-chain and 1-hydrophilic groups, it is not always easy to link two molecules or introduce hydrophobic groups or polar groups. In other words, the method of performing transesterification with an enzyme like the methods of Patent Documents 1 and 2 is poor in selectivity of the group to be transesterified, It was difficult to obtain a compound having a structure with high purity. Therefore, the actual situation is that the 2-chain 1 hydrophilic group-containing surfactant has a great problem in practical use, despite its excellent performance. As a result of diligent research to solve such problems, the present inventors have found that cyclic phosphates in which a cyclic phosphate group is introduced into the double bond portion of an alkyl ester of an unsaturated fatty acid are produced using only inexpensive raw materials. The present invention was completed by finding that it can be easily produced and useful as a 2-chain 1 hydrophilic group-containing surfactant and for the synthesis of other 2-chain 1 hydrophilic group-containing surfactants.

即ち本発明は、下記一般式(1)で示される炭素数10〜26の不飽和脂肪酸のアルキルエステルの二重結合の位置に、環状のリン酸基が導入された下記一般式(2)で示される環状リン酸化物である。   That is, the present invention is represented by the following general formula (2) in which a cyclic phosphate group is introduced at the double bond position of an alkyl ester of an unsaturated fatty acid having 10 to 26 carbon atoms represented by the following general formula (1). It is the cyclic phosphate shown.

For example, when it is used as a surfactant, it is added in a small amount compared to a conventional anionic surfactant containing one chain and one hydrophilic group. Just do it. The cyclic phosphate of the present invention is useful for the synthesis of other different 2-chain 1 hydrophilic group-containing anionic surfactants having a cyclic phosphate group.
