Embodiment 1
[0030] Weigh 5kg of isooctyl methacrylate, 32kg of methyl palm oleate, 12kg of dodecyl methacrylate, 15kg of dioctyl phthalate, 1kg of isopropyl benzoate and dibutyl dithio Add 6kg of zinc carbamate into the mixing tank, heat up to 80°C, and react with 20KHz ultrasonic stirring for 2 hours. Cool to room temperature, then add 6kg of 2,4-dimethyl-6-tert-butylphenol, 3kg of N,N'-disalicylidene-1,2-propylenediamine, 5kg of diethylene glycol monomethyl ether, Diethylaminoethyl methacrylate 4kg, 2-n-octyl-4-isothiazolin-3-ketone 7kg, N-phenyl-N-sec-butylphenylenediamine 4kg, continue to stir for 20 minutes to reconcile evenly, prepare 100kg civil alcohol-based liquid fuel additive.
[0031] Take 8kg of the above-prepared additive and add it into 92kg of methanol to prepare 100kg of alcohol-based liquid fuel. The metal corrosion inhibition performance and other basic properties of the fuel are tested.
[0032] Metal corrosion inhibition performance test refers to SAEJ 1747 "Recomme...
Embodiment 2
[0038] Take by weighing isooctyl polymethacrylate 7kg, methyl palm oleate 28kg, lauryl methacrylate 14kg, dioctyl phthalate 11kg and zinc dibutyl dithiocarbamate 8kg, add to In the mixing tank, the temperature was raised to 80° C., and the mixture was stirred and reacted with 20 KHz ultrasonic waves for 2 hours. Cool to room temperature, then add 10kg of 2,4-dimethyl-6-tert-butylphenol, 2kg of N,N'-disalicylidene-1,2-propylenediamine, 3kg of diethylene glycol monomethyl ether, Diethylaminoethyl methacrylate 6kg, 2-n-octyl-4-isothiazolin-3-ketone 5kg, N-phenyl-N-sec-butylphenylenediamine 11kg, continue to stir for 20 minutes to reconcile evenly, prepare 100kg civil alcohol-based liquid fuel additive.
[0039] Test the performance of the additive according to the method of Example 1, and the results are shown in Table 3 and Table 4.
