Application of polycrotonaldehyde, obtained from recycling the waste “yellow oil”, in production of lubricants

The impact of polycrotonaldehyde, extracted from the waste “Yellow oil” produced during the alkaline treatment of pyrogas at Shortan gas chemical complex, on its properties lubricants as a dispersed medium and a dispersed phase after it is added to them have been studied in this paper. It has been established that polycrotonaldehyde can be used as a dispersed phase in the production of lubricants. Based on the research results, it has been proven that the addition of 2.5% to 7.5% of polycrotonaldehyde in the production of lubricants gives a positive result. The lubricant prepared by adding 5% of polycrotonaldehyde as a dispersed phase had a penetration number of 271 and a dropping temperature of 119 °C.
