摘　　要：研究发现在０．３Ｔ磁场强度下乙酸与正丁醇混合酯的生成量最高，正丁醇的粘度和表面张力的下降率最大。ＩＲ显示经磁场处理后，正丁醇的羟基伸缩振动吸收峰变窄，表明，磁场能够降低体系内分子间的氢键缔合，增强醇与酸的反应活性。Under the condition of 0.3T magnetic field intensity,the product of the esterformed by mixing,n-butyl alcohol with acetic acid in equal molar ratio is the highest and thedecreasion of the viscosity and the surface tension of the processed,n-butyl alcohol is thebiggest.IR also shows that the stretching and vibrating absorption of hydroxyl in the pro-cessed n-butyl alcohol narrows. The results prove that the magnetic field can decrease aggre-gation degree of hydroxyl bond between molecules and increase the reacting activity of n-butyl alcohol and acetic acid.
