【摘要】 以硬脂酸、氢氧化铝为原料,冰乙酸为催化剂,熔融法合成硬脂酸铝。通过单因素实验和正交实验考察了反应时间、反应温度、催化剂用量对产品产率和铝含量的影响,并确定其最佳的反应条件为:反应时间6h,反应温度140~150℃,催化剂用量11%。此反应条件下得到产品产率和铝含量分别为85.6%和4.97%,熔点145~155℃。采用傅里叶-红外光谱仪(FT-IR)、同步热分析仪(TG)、X射线荧光光谱仪(XRF)对产物进行了表征,并确定了目标物的成分及结构。更多还原

【Abstract】 Fusion processes for the synthesis of aluminum stearate by reacting stearic acid with aluminum hydroxide,ice acetic acid as the catalyst was investigated. Single factor experiments and orthogonal experiments were carried out to analyze the influence of reaction time,reaction temperature and the amount of catalyst on the yield and aluminum content in the product. The optimal reaction conditions were obtained as follows: reaction time 6h,reaction temperature 140 ~ 150℃,and the amount of catalyst 11%. Under these conditions,the product yield was 85. 6%,the aluminum content in the product was 4. 97% and the melting point was 145 ~ 155℃. The compositions and structures of the product were identified by Fourier Transform Infrared Spectrometer( FT- IR),Synchronous Thermal Analyzer( TG) and X- ray Fluorescence Spectrometer( XRF).更多还原
