diethyl carbonate meaning in Chinese
碳酸二乙酯
Examples
- 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。 - 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
我们现在发现如果反应在一种沸点在一百摄氏度以上的碳氢化合物中，例如甲苯中进行，那么大部分或者全部的过量的昂贵的二乙基碳酸酯就可以被碳氢化合物所取代。 - 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
因此我们提出了按照这一系统使用过量的二乙基碳酸酯（后面作为溶剂）强迫平衡向所要的方向移动，当反应基本上完全完成后蒸馏平衡向来生产二乙基苯基丙二酸酯。 - 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。
