【摘要】 对4种脂肪醇在不同温度下自液体石蜡中在镁和氧化镁表面的等温吸附进行了实验研究。结果表明:在288～333K的温度范围内,脂肪醇在镁粉表面的吸附量均随温度的升高而增大。脂肪醇烃链中碳原子的个数对醇的吸附量也有重要影响,低级脂肪醇在镁表面的吸附量随碳原子数量的增加而减少,而高级脂肪醇的吸附量随碳原子数量的增加而增加。脂肪醇在氧化镁表面的平衡吸附量均随烃链中碳原子数量的增加而增加。更多还原

【Abstract】 The isothermal adsorptions of four fatty alcohols from liquid paraffin solution on magnesium and magnesium oxide have been measured under different temperature. The results show that the adsorption amount of fatty alcohol on magnesium powder increases with the increase of temperature during the temperature from 288K to 333K. The amount of carbon atom in the hydrocarbon chain of fatty alcohol has important effect on the adsorption amount of fatty alcohol. For the short hydrocarbon chain alcohol,the adsorption amount increases with the decrease of the amount of carbon atom;but for long hydrocarbon chain alcohol,the adsorption amount increases with the increase of the amount of carbon atom. In addition,the equilibrium adsorption amount of fatty alcohol on magnesium oxide increases with the increase of the amount of carbon atom in hydrocarbon chain.更多还原
