Substance combinations which contain (1) an inorganic salt of nitrous acid, (2) a water-insoluble polysubstituted phenol, (3) an aliphatic ester of a dihydroxybenzoic acid, and (4) a tocopherol plus optionally (5) a suitable water vapor-volatile bicyclic terpene or an aliphatically substituted naphthalene which promotes sublimation of the components present in the respective substance combination, especially in air at a relatively high atmospheric humidity, and the use of such substance combinations as vapor phase corrosion inhibitors in packaging or in storage in closed spaces for protection of the conventional metals for use such as iron, chromium, nickel, tin, zinc, aluminum, copper and their alloys against atmospheric corrosion are described.
含有(1)亚硝酸的无机盐,(2)不溶于水的多代苯酚,(3)二羟基苯甲酸的脂肪族酯,(4)生育酚,以及(5)适当的水蒸气挥发性双环萜烯或脂肪族取代的萘的物质组合,可促进相应物质组合中存在的成分升华、特别是在大气湿度相对较高的空气中,以及将此类物质组合作为气相腐蚀抑制剂用于包装或封闭空间的储存,以保护铁、铬、镍、锡、锌、铝、铜等传统金属及其合金免受大气腐蚀。
