摘　　要：以氰乙酸乙酯和多聚甲醛为原料合成α 氰基丙烯酸乙酯 ,无催化合成的最优反应条件是 :n(CNCH2 COOC2 H5)∶n[(HCHO) n]=1 0 0∶1 0 5、反应温度 82～ 85℃、溶剂 (乙酸乙酯 )用量 2 0 0mL mol氰乙酸乙酯、反应时间 3h ,合成收率 58.2 % (质量分数≥ 99 0 % )。Ethylαcyanoacrylate (Ⅰ) was synthesized by condensation of ethyl cyanoacetate(Ⅱ) and paraformaldehyde(Ⅲ) without catalyst. The optimum conditions of the noncatalytic synthesis ofⅠ were obtained:molar ratio of Ⅱ to Ⅲ=100∶105,reaction temperature=82-85 ℃, ratio of solvent(ethyl acetate) to Ⅱ=200 mL/molⅡ, reaction time=3 h. The yield was 58.2% (the purity ≥99.0%).
