A vapour-phase corrosion inhibitor (VCI) needs to be a volatile compound or a mixture of compounds. It reaches the surfaces that need to be protected from corrosion via the vapour phase and forms a relatively stable bond at the interface of the metal. Furfural and furfural derivatives were reacted with different amines to produce potential VCIs. The products were evaluated using a humidity chamber method. A suitable vapour pressure is a requirement for a VCI. Conventional vapour-pressure measurement methods require specialised instruments and are labour-intensive. Thermal analysis techniques, such as thermogravimetry (TG), provide a simple experimental set-up. TG also allows rapid and convenient estimation, using small amounts of substances
