Abstract

Polymeric additives with methacrylate functional comonomers (2-(diethylamino)ethyl, 2-(diisopropylamino)ethyl and 2-(tert-butylamino)ethyl methacrylate) were synthesized, and their influence on the low-temperature properties of diesel fuel was studied. The crystallization behavior of the additives and the formulated diesel was observed by differential scanning calorimetry and optical microscopy with polarization. Low-temperature properties of diesel fuel—cold filter plugging point (CFPP) and pour point (PP) were conducted according to standard test methods. The synthesized additives had a great effect on the crystallization behavior of paraffins in diesel fuel by changing the morphology, number and size of crystals. Moreover, all of the synthesized additives greatly improved the low-temperature filterability, with the best improvement achieved by the additive containing 2-(diethylamino)ethyl methacrylate (DEAEMA) in the structure improving the CFPP value by 10 °C and the PP value by 27 °C.
