The present invention relates to a method for stabilizing a halogenated hydrocarbon solvent composition, and more specifically, the present invention relates to a method for stabilizing a halogenated hydrocarbon solvent composition, and more specifically, it comprises adding benzotriazoles and nitroalkanes in combination to a solvent composition to which an amine surfactant has been added. This article relates to a new stabilization method that is also effective against contact with copper and zinc. As a means of removing water present on the surface of metals, plastics, or other solids, there is a method of using a dewatering agent composition prepared by adding various surfactants to a halogenated hydrocarbon solvent such as trichlorotrifluoroethane. Are known. For example, Japanese Patent Publication No. 45-34197, Japanese Patent Publication No. 49-129961
Please refer to the publication. Regarding such water draining agent compositions, Japanese Patent Publication No. 46-3873 and Japanese Patent Publication No. 51-1989
20792, Special Publication No. 53-1236, Special Publication No. 52-22838, Special Publication No. 53-39394, No. 45683 No. 54-45683, Special Publication No. 1973-
There are various proposals such as 12105 and Tokuko Sho 46-12036.
Thus, water is usually removed by immersing an article, such as a metal product, moistened with water in a boiling bath of the above-mentioned dewatering agent composition. According to research conducted by the present inventors, the following difficulties were found when drying copper products and zinc products using the above-mentioned draining agent composition. That is, the boiling bath of the draining agent composition corrodes copper and zinc, and also causes discoloration and clouding. The above-mentioned tendency is particularly noticeable in draining agent compositions in which amine-based surfactants are employed. As a result of various studies and examinations based on the above recognition, the present inventors have discovered that by adding benzotriazoles and nitroalkanes together as anticorrosive agents, halogenated carbonized carbide containing amine surfactants can be produced. It has been found that hydrogen-based solvent compositions can be effectively stabilized against contact with copper products and zinc products. When adding nitroalkanes alone, almost no stabilizing effect is observed, and when adding benzotriazoles alone, although some effect is observed on copper products, it is hardly stable on zinc products. No effect was observed. Thus, the present invention combines benzotriazoles and nitroalkanes with a draining agent consisting of a halogenated hydrocarbon solvent composition containing amines or a reaction product obtained by neutralizing amines with acids as a surfactant. The present invention provides a novel method for stabilizing a draining agent comprising a halogenated hydrocarbon solvent composition. In the present invention, as the benzotriazole, methylbenzotriazole, 5-nitrobenzotriazole, etc. having an alkyl substituent can also be employed, but benzotriazole itself without a substituent is particularly suitable. Further, as the nitroalkanes, nitromethane is suitable, but nitroethane, 2-nitropropane, etc. can also be used, and they are usually selected from nitroalkanes having 1 to 3 carbon atoms. In the case of nitro compounds such as nitrobenzene, no stabilizing effect is observed in the system of the present invention even when used in combination with benzotriazoles. The amount of benzotriazoles and nitroalkanes added is not particularly limited, but usually 0.0001 to 0.1 weight of benzotriazole per 100 parts by weight of the halogenated hydrocarbon solvent composition containing the specific surfactant. parts, preferably 0.001 to 0.05 parts by weight, and 0.0001 to 3 parts by weight of nitroalkanes,
It is preferably selected from a range of about 0.001 to 0.1 part by weight. If the amount added is too small, no stabilizing effect will be observed, and if the amount added is too large, the effect will not increase proportionally.
When used as a draining agent composition, etc., there is an increased tendency to cause problems due to impurities. In the present invention, the halogenated hydrocarbon solvent which is the main component of the solvent composition may be exemplified by various conventionally known or well-known solvents. For example, trichloromonofluoromethane, 1,1,2,2-tetrachloro-1,2-difluoroethane, 1,1,2
-trichloro-2,2-difluoroethane, 1,
2-dichloro-1,2-difluoroethane, 1,
1,1-trichloro-2,2,2-trifluoroethane, 1,1,2-trichloro-1,2,2-
Examples include trifluoroethane, methylene chloride, and trichloroethylene, but 1,12-trichloro-1,2,2-trifluoroethane, which is typical as a draining agent, is a particularly preferred embodiment. Of course, the halogenated hydrocarbon solvent may also contain a small amount of other solvent components, such as alcohol, ketone, ether, etc., or may be an azeotropic composition. Therefore, as an amine surfactant added to the main component halogenated hydrocarbon solvent,
There are no particular limitations, and a wide range of conventionally known or well-known ones may be used. For example, surfactants made of the following amines, or surfactants made of a mixture of such amines neutralized with acids such as carboxylic acid, sulfonic acid, and phosphoric acid, can be employed in the present invention. As amines,

Regarding R 1 to R 3 above, a hydrocarbon group having 4 to 16 carbon atoms is generally preferred, and a hydrocarbon group having 6 to 12 carbon atoms is particularly preferably used. For n, generally n=
1 to 5 are preferable, particularly preferably n=2 to 3
compounds are used. R is a hydrogen atom or a lower alkyl group. X is a halogen atom. In a preferred embodiment, a reaction product of a primary amine having 6 to 12 carbon atoms and a carboxylic acid having 6 to 12 carbon atoms, ie, an amine salt, may be employed as the amine surfactant. For example, C p H 2p+1 NH 2 (p
=6~12) Alkylamine, C p H 2p-1 NH 2
(p=6-12) alkenylamine and C n H 2n+1
COOH (m=5-11) alkyl carboxylic acid,
A reaction product with an alkenylcarboxylic acid such as C n H 2n-1 COOH is preferred, and dioleate of propylene diamine, lauryl dimethylamine, etc. can also be used. Such amine surfactants may be used alone or in combination of two or more. Furthermore, other surfactants can be added to one or more of these to be used in combination. For example, cationic surfactants such as phosphonium salt surfactants and sulfonium salt surfactants, amphoteric surfactants, nonionic surfactants, and the like can be used in combination. The amount of the amine surfactant to be added to the halogenated hydrocarbon solvent is not particularly limited, but it can usually be selected from a range of about 0.001 to 10 parts by weight, preferably about 0.1 to 5 parts by weight, per 100 parts by weight of the solvent. The specific solvent composition stabilized according to the present invention is
Although it can be used for various purposes, it is particularly suitable as a draining agent composition, and can be applied to glass, ceramics, and other solid materials in addition to metals and plastics. For example, it is suitable for drying precision instruments, plastic products that are at risk of thermal deterioration, and electronic equipment parts such as ICs and printed wiring boards as a post-processing and plating process. In particular, the present invention is also effective for copper and zinc, greatly expanding the range of application. Next, in order to clarify the effects of the present invention, a heating reflux corrosion test was conducted with and without the addition of various stabilizer compounds. The following solvent composition was used. 1,1,2-Trichloro-1,2,2-trifluoroethane 99.5% by weight Reaction product of caprylamine and caproic acid 0.5% by weight The heating reflux corrosion test is as follows. That is, 280 g of a solvent composition containing a predetermined amount of stabilizer was placed in a 500 ml round bottom flask, two metal pieces (30 x 15 x 2 m/m) were present in the gas phase and the liquid phase, and heated with a mantle heater. After refluxing for 16 hours, examine the amount of corrosion on the metal pieces, the surface condition of the metal pieces, and the degree of change in liquid color. The evaluation was carried out using the following three-stage evaluation method. That is, the surface condition of the metal piece is 〇: no corrosion (pass), △: partial corrosion (fail), ×: full corrosion (fail), and the degree of change in liquid color is 〇: no change. (passed),
△: Slightly colored (fail), ×: Darkly colored (fail)
