| 摘 要： | α－（6-甲氧基-2-萘基）-乙醇在催化剂的作用下，与甲醇和CO发生羰基化反应，一步生成α－（6-甲氧基-2-萘基）丙酸甲酯（萘晋生申酯）。应用气相色谱-质谱联用技术，对这个反应过程中生成的各种化合物进行了分析，获得两个中间产物6-甲氧基萘乙烯和1-甲氧基-1-（6'-甲氧基-2'-萘基）乙烷的GC／MS数据资料，为推测该催化反应机理提供了可靠的依据。

| Abstract: | alpha-(6-Methoxyl-2-naphthyl) ethanol can be carbonylated to form methyl-alpha-(6-methoxyl-2-naphthyl)propionate catalyzed by a catalyst in the pressnce of methanol. High efficiency capillary gas chromatography and GC/MS technique were used for determining products which were obtained from the carbonylation. An OV-101 fused silica capillary column (25 m x 0.2 mm i.d.) and a flame ionization detector (FID) were employed in the GC analysis. The column temperature was kept at 250 degrees C. Mass spectra were obtained by electron impact at 70 eV. The structures of four compounds were identified. The major product is methyl-alpha-(6-methoxy-2-naphthyl) propionate, and the two by-products are 2-vinyl-6-methoxynaphthalene and 1-methoxy-(6'-methoxy-2'-naphthyl)ethanol. |
