Theoretical and Experimental Investigation on Ratio of Feed Stock for the Production of Percarbamide via Moist Method Wang Hongxian, Ren Baozeng*#, Liu Ying##, Zhao
Hongkun## Abstract Based on ternary phasediagram of urea-hydrogen
peroxide-water at 10° C, the dependence of ratio of feed stock
and yield to hydrogen peroxide for the production of percarbamide via moist method was
investigated. The optimum ratio of feed stock was from 1.242 to 1.396 and the
corresponding mass of percarbamide was 0.178kg and yield to hydrogen peroxide was 21.5%.
Experiment was carried out in a batch reactor, the experimental result was consistent with
that of theoretical analysis.
