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.

Synthesis and application of an alcohol amine with an extended main carbon chain are provided, belonging to the field of chemical building materials. Under the action of a catalyst, tertiary amine is subjected to a two-step substitution reaction, a hydrolytic reaction and a reducing reaction to obtain a novel alcohol amine (NAA). The novel alcohol amine as provided may have a better grinding aid effect than triethanolamine while is added into cement as a cement grinding aid, and thus has a wide application prospect.
