4-甲基-4’-硝基二苯醚的加氢研究

Study of Hydrogenation of 4-Methyl-4 -nitrodibenzene Ether

在０．８ＭＰａ、５５℃、无水乙醇为介质及Ｐｄ／Ｃ为催化剂的条件下，对４－甲基－４’－硝基二苯醚的加氢反应进行了研究，经实验确定最佳的反应条件为：装料系数为１／３，硝基物（ｇ）与溶剂（ｍｌ）的配比为１／３，产品的产率９２％以上，经气相色谱分析产品纯度达到９９％以上。

The hydrogenation of 4-methyl-4' -nitrodibenzene ether was studied in CH_3 CH_2OH using Pd/C as catalyst at 0. 8MPa and 55℃. The optimum conditions of the reaction were determined: coefficient of chop 1/3, proportion of nitrodibenzene ether (g) to solvent (ml) l: 3. The yield of the product over 92%, the purity of the product was over 99% by GC analysis.
