Abstract
Citric acid—neopentylene glycol—citric acid (CNC) triblock claw molecule as a fuel additive was applied as a diesel fuel low-temperature flow improver. Some of the other molecules—such as stearic acid and hexadecyl alcohol—are trapped with the above-synthesized claw molecule. The claw molecule, which is hydrophilic before the other molecules trapped into the suitable sites of the claw molecule, becomes soluble in diesel fuel. The claw molecule structure was further confirmed by 1H NMR and IR spectra. The cold filter plugging point of diesel of adding the claw molecule was measured and discussed. The experimental results showed that the newly developed low-temperature flow improver has a good sensibility to diesel of different batches and different composition. When dosage is 600 g/g, the reduction value of cold filter plugging point is up to 6 units.
