The present invention relates to an amphoteric surfactant containing a fluoroalkyl group and a method for producing the same, and more specifically, to an amphoteric surfactant comprising a new compound containing a fluoroalkyl group and a method for producing the same. Conventionally, various surfactants such as anionic, cationic, and nonionic surfactants have been known, and fluorinated surfactants having a fluoroalkyl group such as a perfluoroalkyl group are also known. Fluorinated surfactants exhibit unique surfactant properties, so they can be used as evaporation inhibitors (extinguishing agents) for volatile liquids,
Suitable for use as a leveling agent for photographic gelatin layers, paint additive, and other various uses. Furthermore, anionic fluorinated surfactants are also widely used as emulsifiers in the production of fluororesins. Therefore, amphoteric surfactants are generally less affected by pH changes.
Although it has characteristics such as not being easily affected by salts, no suitable fluorinated amphoteric surfactant has been proposed so far. As a result of various studies and studies on fluorinated amphoteric surfactants from the above-mentioned viewpoint, the present inventor has found that:
We came to the following findings. That is, a fluoroalkylcarboxylic acid derivative obtained according to a method for which the present applicant has separately applied for a patent is combined with two fluoroalkylcarboxylic acid derivatives such as monochloroacetic acid, β-propiolactone, and acrylic acid.
It has been found that by reacting with twice the molar amount or more to simultaneously cause carboxylation and quaternization, a new compound that becomes a betaine type amphoteric surfactant with a specific structure can be produced. For example, the reaction represented by the following chemical formula, The compound obtained by this method has the general characteristics of an amphoteric surfactant, as well as excellent surfactant effects such as being highly effective in lowering surface tension even at low concentrations, and being able to form stable foam with high foaming properties. It shows. Thus, the present invention has been completed based on the above findings, and the general formula

In the novel compound of the present invention, firstly, the number of carbon atoms is 4.
It is important to have ~18 polyfluoroalkyl groups (Rf groups). Generally, the Rf group is preferably a perfluoroalkyl group, and preferably has 6 to 12 carbon atoms. Of course, the Rf group may be linear or branched, and may also be a polyfluoroalkyl group partially containing hydrogen atoms, chlorine atoms, etc. Such polyfluoroalkyl groups, particularly perfluoroalkyl groups, can exhibit various properties as a fluorinated surfactant. Second, -A-OH
The presence of hydroxyl groups is important, and properties such as compatibility with polyvalent salts and good foaming power can be exhibited by such hydroxyl groups. A is a divalent alkylene group having 2 to 3 carbon atoms, and may be linear or branched. Normally, an embodiment in which A is an alkylene group of -CH 2 CH 2 - is desirable from the viewpoint of ease of handling. Thirdly, the anionic −B′− is attached to the cationic nitrogen atom.
It is important that the COO group is bonded,
By such embodiments, various properties as an amphoteric surfactant can be exhibited. In addition, -B-COOM group is bonded to the cationic nitrogen atom, and the -A-
Excellent performance as an amphoteric surfactant in the present invention due to coexistence with OH group and -B'-COO group,
For example, the permissible concentration of polyvalent cations such as calcium ions is high, the effect of suppressing evaporation of organic solvents is large, etc., which can be advantageously exhibited. B
and B' are divalent alkylene groups having 1 to 3 carbon atoms, which may be linear or branched, but are usually linear alkylene groups having 1 to 2 carbon atoms, i.e. -CH 2
- or -CH2CH2- is a preferred embodiment.
Also, B and B' may be different alkylene groups, but
Normally, it is desirable for B and B' to be the same from the viewpoint of manufacturing advantages. In the novel compound of the present invention, Q is a divalent alkylene group having 2 to 6 carbon atoms, preferably 2 to 4 carbon atoms, and may be branched or linear. Generally, a preferred embodiment of Q is a linear alkylene group having 2 to 4 carbon atoms, especially -
CH 2 CH 2 CH 2 − is selected. Further, R is preferably a hydrogen atom or a lower alkyl group having 1 to 3 carbon atoms, and a hydrogen atom is particularly selected. M is a hydrogen atom,
selected from NH 4 or alkali metals, usually M
An embodiment in which is a hydrogen atom may give particularly favorable results. Note that examples of the alkali metal include sodium, potassium, lithium, and rubidium, with sodium and potassium being preferred.

This has been confirmed by means such as infrared absorption spectroscopy, elemental analysis, and isoelectric point measurements. The novel amphoteric surfactant of the present invention has various excellent properties, as shown in the Examples below. That is, in addition to the general properties of the amphoteric type and fluorinated type, such as hard water resistance and pH change resistance, it also has a large ability to lower surface tension. Furthermore, since the critical micelle concentration is small, the above-mentioned effects can be exhibited even at low concentrations. Furthermore, it is possible to form highly foamable and stable foam. Therefore, the amphoteric surfactant of the invention can be widely employed in various applications utilizing the above characteristics. For example, it exhibits excellent effects as a fire extinguisher for flammable liquids such as gasoline, a leveling agent for waxes, a wetting agent for photographic emulsions, and a wetting agent during textile processing. Next, embodiments of the present invention will be described in more detail, but it goes without saying that the present invention is not limited by such explanations. In addition, in the following examples, surface tension and foaming properties were measured as follows. In other words, the surface tension is determined by keeping an aqueous surfactant solution diluted to a predetermined concentration at 25°C and using Wilhelmy
