摘    要:以改性骨架镍为催化剂,催化3-硝基-4-甲氧基乙酰苯胺(NMA)液相选择加氢制备了3-氨基-4-甲氧基乙酰苯胺(AMA)。在反应温度60℃,压力0.15 MPa,m(催化剂)/m(NMA)=1/10时,反应1 h,NMA转化率为100%,AMA的选择性达99.9%。分别以乙醇和甲醇为溶剂考察了催化剂的寿命,在乙醇中催化剂连续套用42次,转化率均为100%,AMA选择性只由99.2%下降到97.0%;在甲醇中连续套用15次,转化率均为100%,AMA选择性均高于99.5%。

关 键 词:改性骨架镍  3-硝基-4-甲氧基乙酰苯胺  催化加氢  3-氨基-4-甲氧基乙酰苯胺

Abstract:Modified skeletal Ni catalyst was used in liquid phase selective hydrogenation of 3-nitro-4-methoxyacetanilide(NMA) to prepare 3-amino-4-methoxyacetanilide(AMA).The conversion was 100% and the selectivity was up to 99.9% under the conditions of 60 ℃,0.15 MPa,1 h and m(catalyst)∶m(NMA)=1∶10.The catalyst showed excellent performance in either ethanol or methanol.When the catalyst was repeatedly used for 42 times in ethanol,the conversion of NMA retained 100% and the selectivity of AMA decreased only to 97.0% from 99.2%.When the catalyst was used for 15 times in methanol,the conversion retained 100% and the selectivity of AMA was always higher than 99.5%.
Keywords:modified skeletal-Ni  3-nitro-4-methoxyacetanilide  catalytic hydrogenation  3-amino-4-methoxyacetanilide
