示すベンゾトリアゾール類は気化性が弱い。Many substances have been proposed and put into practical use as volatile corrosion inhibitors, but most of these are corrosion inhibitors for ferrous metals, and it has been desired to develop something that is effective for both ferrous and non-ferrous metals.9 Nitrite amine salts is a typical volatile corrosion inhibitor, and although it has an excellent anticorrosion effect on ferrous metals, it has no anticorrosion ability on nonferrous metals such as copper. In addition, amine salts of fatty acids are similarly effective against iron-based metals, but
It has no effect on non-ferrous metals. Benzotriazoles, which have excellent anticorrosion effects on nonferrous metals, have weak vaporizability.

条件となる。The characteristics of the present invention are that alkylaminotriazoles have appropriate vapor pressure at high temperatures or below the boiling point of water, maintain volatility even when alkaline metals such as sodium, potassium, and magnesium coexist, and have excellent thermal stability. It has an excellent effect on preventing corrosion of non-ferrous metals such as ferrous metals and copper. Corrosion prevention systems that are exposed to high temperatures, such as engine cooling systems and boiler can water systems, incorporate many types of metals, including iron and copper, and must be protected against corrosion. Among these, iron-based metals and copper-based metals are important factors for corrosion protection. Therefore, the liquid property is always set in the alkaline region, and the necessary condition is that the liquid vaporizes and volatilizes in the alkaline region.

することの利点は、液と接しない部分の金属、蒸気が通
過するパイプや熱交換器などの防食に有効に作用するも
のであり工業的な意義が誠に大きい。The alkylaminotriazoles according to the present invention do not form salts with alkali metals such as sodium and potassium, and alkaline earth metals such as calcium and magnesium, and behave in the same way as amines, and are volatile even in alkaline regions. , is best suited for this purpose. The advantage of having volatility is that it effectively acts to prevent corrosion of metal parts that do not come into contact with liquid, pipes through which steam passes, heat exchangers, etc., and is of great industrial significance.
アルキルアミノトリアゾール類の防食機構は、金属表面

膜を形成して金属を腐食から保護するものと推定するこ
とができる。The anticorrosion mechanism of alkylaminotriazoles can be presumed to be that alkylaminotriazoles are adsorbed onto the metal surface to form a dense adsorption film to protect the metal from corrosion.
本発明に係るアルキルアミノトリアゾール類は、アミノ
グアニジンの酸塩と脂肪酸とからなる公知の合成方法に
よって容易に製造することができる。The alkylaminotriazoles according to the present invention can be easily produced by a known synthesis method using an aminoguanidine acid salt and a fatty acid.

ｐａ＋以下の使用濃度では防食性が充分でなく２０００
０ｐｐ＠以上いくら添加しても、もはやそれ以上防食率
の向上は望めない。Alkylaminotriazoles have insufficient solubility in water, so when using them, they must be solubilized with a solvent such as alcohol, glycol, ketone, or amide, or with an acid such as phosphoric acid or hydrochloric acid, morpholine, hydrazine, etc. You can take a method to do so. The allowable addition concentration is in the range of 0.01 to 20,000 ppm, preferably in the range of 0.5 to 5,000 ppm. 0.01p
If the concentration used is less than pa+, the corrosion resistance will not be sufficient and 2000
No matter how much it is added above 0 pp@, no further improvement in corrosion protection can be expected.
