Process for the manufacture of a dialkylphenylethylmalonatewhich comprises adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of methyl, ethyl or a propyl alcohol, subsequently adding an approximately equivalent proportion of a dialkylcarbonate and of an alkyl phenylacetate, the alkyl groups in these two last-mentioned compounds being preferably the same as the alkyl radical of the above –mentioned lower aliphatic alcohol, heating the mixture to induce reaction and continually distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so formed to interact with an ethylating agent.

生产二烷基苯基丙二酸酯的工艺过程:这包括这包括把至少处于化学平衡的甲醇,乙醇或丙醇添加到覆盖着沸点超过一百摄氏度的碳氢化合物溶剂中,接着加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯,在刚才提到的化合物中,其烷基集团最好是和刚才提到的低级别脂肪族醇相同,然后加热反应混合物从而引导反应的进行,在反应区域通过连续蒸馏移除形成的醇类。最后使所形成的钠代二乙基苯基丙二酸酯和乙基化试剂反应。

Accordingly a further feature of the invention is a combined process wherein a dialkyl phenylethylmalonate is made from an alkyl phenylacetate and a dialkyl carbonate by a process comprising adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of a lower aliphatic alcohol, subsequently adding an approximately equivalent proportion of a dialkyl carbonate and of an alkyl phenylacetate, heating the mixture to induce reaction and continuously distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so obtained to interact with an ethylating agent, such as ethyl halide, diethyl sulphate of ethyl p-toluene-sulphonate.

因此,本发明的另一个应用是一个组合工艺过程:二烷基苯基乙基丙二酸酯由烷基乙酸苯酯和二烷基碳酸酯得到,具体工艺过程是:向覆盖有沸点超过一百摄氏度的团庆化合物溶剂的金属钠中添加至少化学平衡的低级脂肪族醇,然后加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯,加热混合物引导反应进行,持续蒸馏把形成的醇类从反应区域移出,最后使获得的二乙基苯基丙二酸酯和乙基化试剂如卤代乙烷,二乙基硫酸酯形成乙基p-甲苯磺酸酯。
