【Abstract】 Octadecyl secondary amine derivatives can influence the cold flow ability of waxy diesel. The secondary amine derivatives can improve the low temperature properties of diesel, lowering its cloud point and cold filter plugging point, mainly through increasing the solution of long chain normal paraffin in diesel. The combination of very low amount of secondary amine with flow improver T1804 can enhance the dispersion of wax crystals, and help reducing the cold filter point.更多还原
