Summary: | The invention relates to the technical field of floating agent synthesis, and discloses a synthetic method of N,N-dibutyl dithio methyl acrylate sulfur-nitrogen ester. The synthetic method comprises the following steps: mixing and adding 26-32 parts of carbon disulfide and 20-32 parts of methyl acrylate into a reaction container; then dropwise adding 40-52 parts of di-n-butylamine into the reaction container slowly, cooling and stirring, wherein the dropping speed is controlled to be 0.5-1 mL/min, and the reaction temperature is controlled to be not more than 20 DEG C; after the adding and an exothermic reaction are finished, preserving the temperature under the condition of 30-50 DEG C, and stirring for 1-2 h to obtain a crude product; obtaining excessive carbon disulfide in the crude product through reduced pressure distillation so as to obtain a qualified N,N-dibutyl dithio methyl acrylate sulfur-nitrogen ester product. The N,N-dibutyl dithio methyl acrylate sulfur-nitrogen ester is synthetized in one step |
