The reaction time can be appropriately changed depending on the reaction temperature, and is preferably about 1 to 5 hours. After completion of the reaction, the compound (7) can be obtained by distillation purification.

化合物(7)を製造する方法としては、液相フッ素化だけでなく、理論的には電解フッ素化法(ECF法)も採用できる。しかし、本発明の効果を充分に発揮するには、ペルフルオロの基に分岐部分を有する他の化合物を混在させないことが好ましい。該他の化合物は、製造工程で副生しうる化合物である。たとえば、ECF法を採用した場合には、分岐鎖を有するペルフルオロポリエーテル基を副生し、生成物が直鎖の基と分岐鎖を有する基の有する化合物が混在して得られる傾向がある。またテロメリゼーション法も理論的には採用できるが、該方法の場合には、生成物は通常は複数の鎖長の混合物となる。オリゴメリゼーション法では、収率が低くなるおそれがある。よって、該副生物の混在を防止し、効率よく化合物(7)を得るには、液相フッ素化法を経由する製造工程を採用するのが好ましい。   As a method for producing the compound (7), not only liquid phase fluorination but also an electrolytic fluorination method (ECF method) can be adopted theoretically. However, in order to sufficiently exhibit the effects of the present invention, it is preferable not to mix other compounds having a branched portion in the perfluoro group. The other compound is a compound that can be by-produced in the production process. For example, when the ECF method is adopted, a perfluoropolyether group having a branched chain is by-produced, and the product tends to be obtained by mixing a compound having a linear group and a branched chain group. Although the telomerization method can also be theoretically adopted, in this method, the product is usually a mixture of a plurality of chain lengths. In the oligomerization method, the yield may be lowered. Therefore, in order to prevent the by-product from being mixed and obtain the compound (7) efficiently, it is preferable to employ a production process via a liquid phase fluorination method.

本発明のフッ素系界面活性剤は、該カルボン酸(7)のカルボキシル基を式−CON(R)Z(式中の記号は前記と同じ意味を示す)に変換することにより得られる。該変換の方法は、公知のカルボン酸の末端を誘導化方法が採用できる。   The fluorosurfactant of the present invention can be obtained by converting the carboxyl group of the carboxylic acid (7) into the formula —CON (R) Z (wherein the symbols have the same meaning as described above). As the conversion method, a known method of derivatizing the terminal of the carboxylic acid can be employed.

たとえば、該カルボン酸、または該カルボン酸エステルとをHN(R)−R−NR(R、R、R、Rは上述と同じ)と反応させ、アミド結合を生成する。このジアミンとの反応は、水または水溶性溶媒の存在下であっても不存在下であっても実施できる。水溶性溶媒を使用する場合には、ペルフルオロ化合物とジアミンの両者を溶解させる溶媒を用いるのが好ましい。アミド化反応の反応温度は、0℃〜150℃が好ましく、特に10℃〜80℃が好ましい。圧力は、大気圧〜1MPa(ゲージ圧)が好ましく、特に大気圧付近が好ましい。 For example, the carboxylic acid or the carboxylic acid ester is reacted with HN (R 1 ) —R 2 —NR 3 R 4 (R 1 , R 2 , R 3 , R 4 are the same as described above), and an amide bond is reacted. Generate. This reaction with the diamine can be carried out in the presence or absence of water or a water-soluble solvent. When a water-soluble solvent is used, it is preferable to use a solvent that dissolves both the perfluoro compound and the diamine. The reaction temperature of the amidation reaction is preferably 0 ° C to 150 ° C, and particularly preferably 10 ° C to 80 ° C. The pressure is preferably from atmospheric pressure to 1 MPa (gauge pressure), and particularly near atmospheric pressure.

さらに得られたアミンを親水化する反応についても、公知の方法を用いることができる。四級アンモニウム塩化する場合の反応は、水または水溶性溶媒の存在下であっても不存在下であっても実施でき、R−X(は、式(Za)と同様、Xはハロゲン原子であり、好ましくはヨウ素原子)と反応させる。また、X−C2nCOOHとを反応させて、四級化させることもできる(Zbに相当)。この場合、生成した−COOH基を水酸化ナトリウムや水酸化カリウムなどの塩基と処理し、カルボン酸塩基としてもよい。 Further, a known method can be used for the reaction of hydrophilizing the obtained amine. The reaction in the case of quaternary ammonium chloride can be carried out in the presence or absence of water or a water-soluble solvent, and R 5 —X (in the same manner as in formula (Za), X is a halogen atom And preferably with an iodine atom). Further, it can be made quaternized by reacting with X—C n H 2n COOH (corresponding to Zb). In this case, the produced —COOH group may be treated with a base such as sodium hydroxide or potassium hydroxide to form a carboxylate base.

また、アミド化によって生成したCFCFOCFCFOCFCON(R)−R−NRの窒素原子は、水または水溶性溶媒の存在下、過酸化水素や有機化酸化物によってCFCFOCFCFOCFCON(R)−R−N(→O)Rに変換して、化合物(Zc)等の本発明のフッ素系界面活性剤が製造できる。 In addition, the nitrogen atom of CF 3 CF 2 OCF 2 CF 2 OCF 2 CON (R 1 ) —R 2 —NR 3 R 4 produced by amidation is hydrogenated or organically formed in the presence of water or a water-soluble solvent. The fluorine-based surfactant of the present invention, such as compound (Zc), is converted into CF 3 CF 2 OCF 2 CF 2 OCF 2 CON (R 1 ) —R 2 —N (→ O) R 3 R 4 by an oxide Can be manufactured.

カルボン酸(7)をHN(R)−R−COOR(Rは、水素原子、またはカルボキシル基の保護基)と反応させ、アミド結合を生成し、CFCFOCFCFOCFCON(R)−R−COORを得る。Rが水素原子以外の保護基である場合は、加水分解によって、水素原子に変換し、さらに塩化することにより、前記化合物(Zd)へ変換してもよい。本反応は水または水溶性溶媒の存在下であっても不存在下であっても実施できる。 Carboxylic acid (7) is reacted with HN (R 1 ) —R 2 —COOR 7 (R 7 is a hydrogen atom or a protecting group for a carboxyl group) to form an amide bond, and CF 3 CF 2 OCF 2 CF 2 OCF 2 CON (R 1 ) —R 2 —COOR 7 is obtained. When R 7 is a protecting group other than a hydrogen atom, it may be converted into a hydrogen atom by hydrolysis and further converted into the compound (Zd) by chlorination. This reaction can be carried out in the presence or absence of water or a water-soluble solvent.
