Abstract: 2methylidenebutanedioyl dichloride(Itaconyl chloride) was synthesized using itaconic acid and phosphorus pentachloride as raw materials by melting method. The effect of raw material ratio, reaction time, temperature and other process conditions on yield of product was examined. The structure of the product was characterized by IR and 1HNMR .The experiments showed that, when the itaconyl chloride and phosphorus pentachloride molar ratio was 1∶2.2, reaction temperature was 110 ℃ and reaction time was 2 h, the yield of 2methylidenebutanedioyl dichloride can reach 86% and its purity was more than 94%.
