金属腐蚀是一个常见的和普遍的严重问题。据统计1980年我国由于腐蚀造成的直接和间接损失约为140亿元,相当于国民经济生产总值的2%。防止金属腐蚀有多种方法,而使用缓蚀剂是一种比较经济、有效和通用的途径。咪唑啉化合物是一类用途广泛、发展迅速的两性和阳离子表面活性剂,自1948年以来,美、日、苏、德和英等国广泛开展了合成、结构和性能等方面的研究。国内的研究起步较迟,且应用领域较狭窄。
Metal corrosion is a common and widespread serious problem. According to statistics, direct and indirect losses caused by corrosion in China amounted to about 14 billion yuan in 1980, equivalent to 2% of the GNP. There are many ways to prevent metal corrosion, and the use of corrosion inhibitors is a more economical, effective and common way. Imidazoline compounds are a kind of widely used and rapidly developing amphoteric and cationic surfactant. Since 1948, the research on synthesis, structure and properties of the imidazoline compounds have been extensively carried out in the United States, Japan, the Soviet Union, Germany and Britain. Domestic research started later, and the application of the more narrow.
