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。
