- W2363280332 abstract "Cis-1-propenyl phosphonic acid is a kind of medicine intermediate in the synthesis of phosphonomycin.Pd/C is the catalyst in the preparation from 1, 2-propadienyl-phosphonic acid to cis-1-propenyl phosphonic acid.The catalysts have been prepared by immersion method and the activity of the catalysts depends on several factors.The optimum preparation conditions have been confirmed that the adsorption temperature is 313 K,the adsorption time is 6.0 h,the reductant consumption is ten-time level,the reducing temperature is 353 K,the reducing pH is 8.0,and the reducing time is 2.0 h.The activities on the catalyst have been measured at 328 K,0.3 MPa for 2.0 hours.The reaction conversion of 1,2-propadienyl-phosphonic acid can be up to(52.58 %).In addition,The relation between the activity and the microscopic structure of the catalysts has been investigated by XRD,H_2-TPR and BET." @default.
