【 摘 要 】

Itaconyl chloride was synthesised using the bio-based itaconic acid (IA) and phosphorus pentachloride (PCl5) as raw material by a molten method. The effects of various main factors, i.e. The solvent effect on the quality of the product during the purifying process was studied. The ratio of raw materials, the vacuum distillation temperature and vacuum distillation time on itaconyl chloride preparation were investigated. The optimum conditions of synthesis were determined as f ollows: toluene as purified solvent, n(PCl5):n(IA) = 2.15:1, the vacuum distillation temperature 80 °C, the vacuum distillation time 2 h. The yield of itaconyl chloride could reach 90 % and its purity was more than 98 %. The structure of itaconyl chloride was confirmed by means of Fourier Transform Infra-Red (FT-IR) and Nuclear magnetic resonance hydrogen spectrum (1H-NMR).
