Experimental example:
in the test, the antiknock agents of the examples and the comparative examples are respectively added into gasoline according to the volume ratio of 2% to carry out octane number detection and colloid content detection. The detection standards are GB/T503-2016 (gasoline octane number determination (motor method)), GB/T5487 2015 (research method) for gasoline octane number determination, and GB/T8019 2008 for jet evaporation method for determining the content of fuel colloid.

The results show that: the antiknock performance of the gasoline is obviously improved by adding the antiknock agent of the embodiment, the RON reaches more than 95, the AKI reaches more than 90, and the antiknock performance of the gasoline is excellent.
