摘    要:用CuCl,甲醇和空气为原料,合成了甲醇氧化羰基化反应催化剂甲氧基氯化铜,最佳的合成条件是:55度,8h,CuCl与璃的比为1:40(重量比),甲氧基氯化铜的产率为94.5%,对甲氧基氧化铜的溶解进行了讨论;18度时,甲氧基氯化铜在5.3%的氯化氢甲醇溶液中的溶解度为12.3%,用IR,TGA和XRD对所合成的甲氧基氯化铜进行了表征,在IR图谱中发现了官能团-OCH3,CH3的特征吸收峰,证明所合成的产物为甲厮氯化铜,XRD谱显示三个强峰,分别 位于2θ=11.9度,28.6度,47.5度处,根据TGA知该化合物高于180度时会分解,其失重率为17.5%,与理论值17.7%相当。

Abstract:Cupric methoxychloride is synthesized by CuCl, CH3 OH and air at ambient condition, and the conversion of CuCl is 94.5% at 55℃, reaction time is 8h and WMeOH: WCuCl = 40: 1. The solubility of cupric methoxychloride is 12.3% at 18℃ in HClCH3OH solution, in which the concentration of HC1 is 5.3%. The cupric methoxychloride was characterized by FTIR, TGA and XRD. IR spectrum show that the bands at 2 936 cm-1 and 2 826 cm-1 could be assigned to the vibration of- OCH3 and - CH3 in the CuOCH3Cl molecule, and the bands at 517cm-1 and 465cm-1 could be assigned to the Cu - O vibration. XRD result show that CuOCH3Cl has three strong bands at 2θ = 11.9°, 28.6° and 47.5° respectively, although CuC1 has the same bands at 28.6° and 47.5°. The product CuOCH3 C1 will decompose above 180℃ with the loss ratio of weight 17.5%, which is quite in agreement with the result of calculation of formula 17.7%.
Keywords:cupric methoxychloride  cuprous chloride  characterization  solubility
