Diesel has a higher boiling point than gasoline and has many carbon-rich features. Also, since the content of paraffin is high, wax crystals precipitate as the temperature of the winter season falls, resulting in problems such as clogging the filter of the automobile or significantly reducing the fluidity of the fuel. Herein, new comb-like polymers which have paraffin-like alkyl side chain moieties are synthesized from 3-pentadecylphenol, a cardanol derivative, and applied to middle distillate flow improver (MDFI). Also, some polymers containing the similar length alkyl side chains (carbon number = 14, 15, 16) were synthesized and analyzed thermally and chemically. The hundreds ppm of these polymers can improve the cold properties of diesel by co-crystallization with the paraffin wax. As a result, PPDPA is highly effective on the cold properties. Also, in the DSC analysis, we found that PPDPA exhibits different crystalline behavior compared to other polyacrylates. |
