The invention discloses a preparation method of active sulfonyl bagasse xylan-1,1-ferrocene diformate through double esterification. The method comprises the following steps: by using bagasse xylan as a starting material and tungstophosphoric acid as a catalyst, carrying out synthesis in an amino sodium trisulfonate solution; then in a dimethyl formamide solution, by using 1,1-ferrocene diformic acid as an esterifying agent, carrying out secondary esterification reaction under an effect of a triethylamine catalyst to synthesize the sulfonyl bagasse xylan-1,1-ferrocene diformate. Technological conditions for preparing the double esterified active sulfonyl bagasse xylan-1,1-ferrocene diformate disclosed by the invention are easily controlled, the stability of the product is high and the utilization rate of the raw materials is high. Through the double esterification technological method, the double active sulfonyl bagasse xylan-1,1-ferrocene diformate is prepared, a molecule has anti-biological activities produ
