The compound of (C2H6NS)2Zn was synthesized by cysteamine hydrochloride and zinc sulfate heptahydrate as the raw material, used orthogonal experiments to optimize reaction conditions.Optimiza-tion results as follows:using NaOH determined the pH to 10 of the reaction, stirring and maintaining the temperature at 80 ℃.After 1.5 h, the reaction was stopped.The unreacted zinc chloride was filtered, drying the products in 80 ℃with 4 h, the yield was about 89.94% according the content of C2 H7 NS. Through infrared spectrum analysis, high performance liquid chromatograph and content analysis to deter-mine the molecular formula of (C2H6NS)2Zn.The thermigravimetric analysis and electrochenical study proved that the complex can exit in aqueous and not decomposed under 270 ℃.
