在本设计中，正己醇通过脱氢反应而制得正己醛。正己醇为原料，在负载型Cu2O/MgO催化剂的催化作用下制备正己醛。工业上最早采用的生产方法是己酸钙与甲酸反应制得，工艺相对落后，设备腐蚀严重，生产成本偏高。而正己醇气相脱氢法具有反应条件温和、原料单一、反应活性和选择性高、设备简单等多个优点，成为许多国家近年来竞相开发的新工艺。本设计对脱氢反应进行了物料的恒算，热量的恒算，设备选型及对应的计算。最后绘制了生产工艺流程图，主要反应器设备图，车间平面布置图，车间立面布置图。
本设计是对正己醛进行的设计，以学习的基础专业课为基础，设计出合理的工艺流程，选择相应的工艺设备等。其主要目的是提高解决化工产品生产车间实际问题的能力；充分掌握脱氢反应中工艺流程的相关设计、物料恒算、热量衡算、设备选型等基本方法与步骤；在可行性与合理性两个方面上建立恰当的设计思想。同时通过本课程设计，提高运用计算机设计绘图的能力。15470
本设计的计算标准：年生产45000吨；年工作日为300天，45天进行机器检修，15天机动。

An annual output of 50000 tons of N-hexyl alcohol dehydrogenation of n-hexanal process design
Abstract：Hexanal synthetic spices intermediates, is also an important raw material in food industry and pharmaceutical industry, it can be used for preparation of apple and tomato flavor, but also can be used as a plasticizer, rubber, resins, synthetic organic pesticides and so on, with more high economic value
In this design, n-hexyl alcohol by dehydrogenation of n-hexyl aldehyde prepared. Hexanol as raw materials for preparing n-hexanal in catalysis supported Cu2O / MgO catalyst. Industrial production methods used in the first calcium is already prepared by the reaction with formic acid, the process is relatively backward, serious corrosion of equipment, high production costs. And n-hexyl alcohol vapor phase dehydrogenation method has mild reaction conditions, a single raw material, high reactivity and selectivity, simple equipment and many other advantages, a new technology in many countries in recent years competing development.The following process is materials counting, heat counting, equipment selection and calculation. Finally, the flow of production technics is protract including main equipments diagram, materials diagram, a flat disposal picture of the workshop, the solid disposal picture of the workshop.
This design aimed at Hexanal requiring us to design a reasonable process and choose the corresponding process equipments based on the study of professional basic course. It aimed at improving the ability of solving practical problems about the chemical products production workshop design and grasp the relevant design piocess in dehydrogenation, calculation of material constant, calculation of heat balance，equipment selection and calculation . Through this course design, we can also improve the ability of using the design drawing of the computer.
Basis of calculation: annual production of 50000 tons; days to 300 days in，45 days for machine maintenance, 15 days mobile.
Keywords: Hexanal ; Hexanol; dehydrogenation; process calculation
