Hydrocarbon resins (oligomers) are produced on the basis of fraction C9 of oil refining by-products. The low-temperature emulsion oligomerization can reduce the temperature and duration of the process compared to the existing technologies.
The investigated influence of surface tension on the process of emulsion cooligomerization. The synthesis of cooligomers by emulsion cooligomerization of hydrocarbon fraction C9 of liquid products of pyrolysis. The major features of the cooligomerization process of mixture of unsaturated hydrocarbons of fraction C9 have been investigated and optimum conditions have been selected.
Antiwear properties of modern high temperature greases have been studied by simulating various temperature and load conditions on friction machines. Differences in tribological characteristics of greases depending on the nature of their thickeners were determined and explained. Maximum antiwear properties were revealed in conventional complex and overbased complex calcium salicylate, sulfonate and phenolate greases
