Embodiment 1
[0026] Antiknock agent base material: (1) Take 4 parts of hydroquinone, 10 parts of methacrylic acid, 3 parts of p-toluenesulfonic acid, 50 parts of toluene, and 20 parts of isoheptanol in parts by mass, and heat to 90°C Stir and mix for 4 hours, distill under reduced pressure, filter with suction, take the filter residue, wash with distilled water, and dry to obtain a dried product;
[0027] (2) Take methanol and add sodium methoxide at a mass ratio of 10:1, stir and mix at 40°C for 30min to obtain a stirred mixture. Take the stirred mixture and add dry matter and hydroquinone at a mass ratio of 10:5:1, and heat to 70°C Stir the reaction for 3h, and distill under reduced pressure to obtain the reduced pressure distillate;
[0028] (3) Take lithium hydroxide and add lauric acid at a mass ratio of 2:5, stir and mix for 3 hours at 70°C, adjust the pH to 7, and cool to room temperature, to obtain the cooling material, add toluene at a mass ratio of 1:5, stir and mix, filter, and take ...

[0033] Antiknock agent base material: (1) Take 8 parts of hydroquinone, 15 parts of methacrylic acid, 5 parts of p-toluenesulfonic acid, 70 parts of toluene, and 40 parts of isoheptanol in parts by mass, and heat to 100° Stir and mix for 5 hours, distill under reduced pressure, filter with suction, take the filter residue, wash with distilled water, and dry to obtain a dried product;
[0034] (2) Take methanol and add sodium methoxide at a mass ratio of 10:1, stir and mix at 50°C for 40min to obtain a stirred mixture, take the stirred mixture and add dry matter and hydroquinone at a mass ratio of 10:5:1, and heat to 80°C Stir the reaction for 4h, and distill under reduced pressure to obtain the reduced pressure distillate;
[0035] (3) Take lithium hydroxide and add lauric acid at a mass ratio of 2:5, stir and mix at 90°C for 5 hours, adjust the pH to 8, and cool to room temperature, to obtain the cooling material, add toluene at a mass ratio of 1:5, stir and mix, filter, and take ...
Embodiment 3
[0040] Antiknock agent base material: (1) Take 6 parts of hydroquinone, 12.5 parts of methacrylic acid, 4 parts of p-toluenesulfonic acid, 60 parts of toluene, 30 parts of isoheptanol in parts by mass, and heat to 95°C Stir and mix for 4.5h, distill under reduced pressure, filter with suction, take the filter residue, wash with distilled water, and dry to obtain a dried product;
[0041] (2) Take methanol and add sodium methoxide at a mass ratio of 10:1, stir and mix at 45°C for 35min to obtain a stirred mixture. Take the stirred mixture and add dry matter and hydroquinone at a mass ratio of 10:5:1, and heat to 75°C Stir the reaction for 3.5h, and distill under reduced pressure to obtain the reduced pressure distillate;
[0042] (3) Take lithium hydroxide and add lauric acid at a mass ratio of 2:5, stir and mix at 80°C for 4 hours, adjust the pH to 7.5, cool to room temperature, and add the cooling material to toluene at a mass ratio of 1:5, stir and mix, filter, and take The filt...
