  12. It has further been proposed to make diethyl phenylmalonate by taking the system using an excess of the diethyl carbonate ( which then acts also as solvent ) to force the equilibrium over in the desired direction and distilling out the equilibrium until the reaction has gone substantially to completion

    因此我們提出了按照這一系統使用過量的二乙基碳酸酯（後面作為溶劑）強迫平衡向所要的方向移動，當反應基本上完全完成後蒸餾平衡向來生產二乙基苯基丙二酸酯。
  13. We have now found that if the reaction is carried out in presence of a hydrocarbon which boils above 100 c, for example toluene, then much or all of the excess of the expensive diethyl carbonate can be replaced by the hydrocarbon
