Research Development on Carbonylation of Acetylene to Acrylic Acid and Its Esters

Shi Xiaoxian,Tian Hengshui,Zhu Yunfeng(School of Chemical Engineering,East China University of Science and Technology,Shanghai 200237,China)  
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.
