It is also known that sodium ethylate and diethyl phenylmalonate interact together to give ethyl phenylacetate and diethyl carbonate 众所周知，乙醇纳和二乙基苯基丙二酸酯反应可以得到乙基乙酸苯酯和二乙基碳酸酯。
2.
This method , however , involves using a large excess of diethyl carbonate ( for example , 4 - 8 mols . ) ; it also involves preparing sodium ethylate by dissolving sodium metal in ethanol , which process must be carried out very slowly and carefully if it is to be used on a manufacturing scale 但是这一方法涉及到使用大量过量的二乙基碳酸酯（例如， 4 - 8摩尔） ；同时也涉及到在乙醇中溶解纳来制备乙醇纳的反应，这个过程必须非常缓慢小心地进行，如果在工业生产级别上是用这一方法就比较麻烦了。
