The invention discloses a mercaptoethyl dioleate dimethoxycarbonylethyl tin compound. The molecular formula of the compound is shown in the description. Oleic acid is used to synthesize a (reverse) ester tin compound, the change of the (reverse) ester group increases the activity of the (reverse) ester group and realizes good early-stage stability when the (reverse) ester tin compound is used as a stabilizer, and high-molecular-weight oleic acid in the ester makes the compound have excellent lubricity and have the effects not possessed by traditional organic tin. A unique device and a unique technology are adopted, so the reaction effect is good, the efficiency is high, and the application prospect is good.
