The present invention relates to a novel fluorine-containing hydroxybetaine type amphoteric surfactant. Certain perfluoroalkyl group-containing betaines are already known from U.S. Pat. No. 2,764,602, but the hydroxyl group-containing fluorine-containing betaine of the present invention is clearly distinguished from known fluorine-containing betaine compounds. . When attempting to produce fluorine-containing hydroxybetaine based on known techniques, a fluorine-containing hydroxyamine, which is a precursor thereof, must first be produced in the following manner. That is, a hydroxy group-containing diamine must be subjected to a condensation reaction with perfluoroalkylcarboxylic acid, perfluoroalkylsulfonic acid, or an acid halide or ester thereof. However, it is well known that the hydroxyl group in the amine molecule causes various complicated and undesirable side reactions, and the desired fluorine-containing hydroxyamine is hardly obtained (for example, in the literature H. Niederprum et al. , Liebigs Annalen der

を発揮する。A fluorine-containing hydroxyamine represented by the formula: (in which R f , Y, R, R 1 and R 2 are as defined above) is prepared. Next, the terminal amino group in the hydroxyamine is treated with a known compound such as monochloroacetic acid (or various derivatives such as sodium monochloroacetate or ethyl monochloroacetate), propiolactone, propane sultone, sodium monochloropropylsulfonate, or acrylic acid. In this method, a desired fluorine-containing hydroxybetaine type amphoteric surfactant is obtained by applying a quaternizing agent. In this case, when using a quaternizing agent whose hydrophilic groups are masked, such as monochloroacetic alkyl ester, by hydrolyzing the ester group with an acid or alkali after the reaction, fluorine-containing hydroxyl with a zwitterion structure can be used. Betaine type amphoteric surfactants can be produced. The fluorine-containing hydroxybetaine type amphoteric surfactant of the present invention not only exhibits excellent surfactant properties in polar media such as water or alcohol, but also has low dielectric constant properties such as oil, wax, grease, or varnish. It can exhibit excellent surfactant properties even in medium of The following table shows the results of measuring the surface tension of various fluorine-containing betaine type amphoteric surfactant aqueous solutions by varying the pH. Compared to known fluorine-containing betaine type amphoteric surfactants, the fluorine-containing hydroxybetaine type amphoteric surfactant of the present invention exhibits superior surface activity over a wide pH range.
