As the authors found that a promising material for a volatile atmospheric corrosion inhibitor is the use of waste generated in obtaining oil from rapeseed (family Brassicaceae), namely rapeseed meal, appropriate research was qualitative and quantitative determination of its basic compounds. Also found that the inhibition efficiency is extreme character with a maximum protective capacity for 2 hours. Why was it necessary to study changes in the composition of the extract in the evaporation process, and identification of compounds that do not take part in the formation of the film, that is remaining in the non-volatile sludge. The subject of this study is to extract 2-proрanol rapeseed cake extract . The purpose of work - a study of its component composition, namely, volatile and non-volatile compounds. The volatile chemical composition of the rapeseed cake extract involves glycosides, nucleosides, ketone, aldehyde, fatty acids, sterol and alkaloids. The most important compounds in rapeseed cake are: Guanosine , Sucrose , Xanthosine, 3',5'-Dimethoxyacetophenone Benzaldehyde, 4-hydroxy-3,5-dimethoxy, Acetic, Oleic, Linoleic and Palmitic acid and Sterols.
