【摘要】 研究了在乙醛氧化法制备醋酸过程中,乙醛浓度、反应温度、反应压力、反应时间对转化率的影响,发现在反应温度为95℃,反应压强为0.4 MPa,乙醛浓度为15%,反应时间为2.5 h时,转化率最高.通过一系列实验,成功设计出一套安全合理的实验方案,对实验操作过程进行了优化,并对化工工艺实验教学提出了一些建议.更多还原

【Abstract】 Acetic acid was prepared by oxidation of acetaldehyde.The influences of acetaldehyde content,temperature,pressure and time on the reaction yield were studied systematically.The optimum conditions for acetic prepared were found,that is by means of 15?% acetaldehyde solution reacted at 95?℃,0.4?MPa,for 2.5 hours,the reaction yield may arrived to 75?%.A reasonable and safe experiment operation method was obtained through a large number of experiments,besides,the experiment operation proceeding was optimized and some suggestions were given for experiment teaching of the chemical engineering and technology.更多还原
