The present disclosure provides a preparation method of 4-(heptafluoro-2-propyl)-2-trifluoromethylaniline and an application thereof. The preparation method comprises the following steps: reacting 2-aminobenzotrifluoride and 2-bromoheptafluoropropane in the presence of sodium formate or hydrates thereof and a SO.sub.2 reagent, so as to obtain 4-(heptafluoro-2-propyl)-2-trifluoromethylaniline. The present disclosure adds sodium formate or hydrate thereof and the SO.sub.2 reagent during the reaction of 2-aminobenzotrifluoride and 2-bromoheptafluoropropane. Under the cooperation of these two compounds, the yield of the reaction is high. And the purity of the product is high, the operation method is simple, the cost is relatively low, and the pH of the reaction doesn't need to be controlled.

A novel promotor which contains an aniline derivative is introduced. By using the promotor alone, the time and temperature of the curing reaction of the vinyl ester resin can be controlled by the unique steric effect and electronic properties of the aniline derivative. A method for preparing the above promotor is also introduced.
