Embodiment 1
[0019] The composition and mass percentage of the methanol-gasoline composite additive are: 25% of methyl tert-butyl ether, 6% of benzotriazole, 55% of isopropanol, 3.5% of p-toluidine, 0.5% of octadecylamine and 2 , 6-di-tert-butyl-p-cresol 10%,
[0020] The compounding process implementation of this methanol-gasoline composite additive:
[0021] ① First inject methyl tert-butyl ether and isopropanol into the mixing tank according to the ratio, reaching a point slightly lower than 3 / 5 of the volume of the mixing tank, and circulate and mix for about 10 minutes.
[0022] ②Add a certain amount of benzotriazole, p-toluidine, octadecylamine and 2,6-di-tert-butyl-p-cresol into the mixing tank in turn.
[0023] ③Start the mixing tank again, and circulate and mix for about 30 minutes, so that the solids are completely dissolved and mixed evenly.
[0024] ④ After the mixed solution is transferred out, it is filtered, and the filtered filtrate is sealed and stored to obtain the meth...
