    • PURPOSE:To obtain an excellent anticorrosive containing an alkali metal or amine salt of cyclohexyl propionic acid as an effective component and being added to a water-containing medium to be used. CONSTITUTION:Cyclohexyl propionic acid is mixed and reacted with an aqueous solution of an alkali metal hydroxide such as sodium hydroxide and potassium hydroxide to obtain a concentrated aqueous solution of an alkali metal salt of cyclohexyl propionic acid, with which an organic amine is mixed and reacted to obtain an amine salt of cyclohexyl propionic acid. The concentrated solution of an alkali metal salt of cyclohexyl propionic acid and an amine salt of cyclohexyl propionic acid are added to a water-containing medium being in contact with iron such as water in a cooling system, water for hydraulic pressure in tanks and water kept in a full tank. The added amount is in the range of about 0.2-1wt% as an effective component, based on the medium.
    • 目的:获得含有环己基丙酸的碱金属或胺盐作为有效成分并加入待使用的含水介质中的优异防腐剂。 构成:将环己基丙酸与碱金属氢氧化物如氢氧化钠和氢氧化钾的水溶液混合并与其反应,得到环己基丙酸的碱金属盐的浓缩水溶液,将有机胺与其混合并反应 得到环己基丙酸的胺盐。 将环己基丙酸的碱金属盐和环己基丙酸的胺盐的浓缩溶液加入到在冷却系统中与铁例如水接触的含水介质中,储存在水中的水和水保持 在一个满坦克。 基于介质,添加量作为有效成分的约0.2-1重量%的范围。
