摘要
相对于目前主张的丙烯氧化法生产丙烯酸,再酯化生产丙烯酸酯的主流工艺,乙炔羰基化法合成丙烯酸及酯的工艺具有很好的经济性应用价值。文章分析比较了由乙炔羰基化合成丙烯酸及酯的四种方法后,认为其中的两种改进方法具有较高的研究价值;在综述了其反应机理、催化剂、溶剂及阻聚剂的进展后,对合成过程中的问题提出了建议。
Compared with the present process for the synthesis of acrylate by esterification of acrylic acid, which comes by oxygenation of propylene, the process by the carbonylation of acetylene to acrylic acid and its esters pays less cost, and so, is worth to be studied. After describing four ways of the carbonylation, two of these were considered more valuable to research on. And after summarizing the evolvement of the synthesis mechanism, catalysts, solvent and inhibitor, some suggestions counter to the process of synthesis were given
