The manufacturing method
of n-hexane
1. Introduction

n-hexane is a widely used chemical production raw material, mainly used in the extraction of vegetable oil, rubber processing, detergent manufacturing and other fields. With the continuous development of industrial technology, the manufacturing method of n-hexane has been continuously improved and optimized. This paper will introduce the manufacturing method of n-hexane in detail, including the selection of raw materials, reaction principle, process flow, equipment selection and so on.

2. Raw Material Selection

The manufacture of n-hexane mainly uses hydrocarbon raw materials such as petroleum gas and light diesel oil. When selecting raw materials, it is necessary to consider its hydrocarbon composition, purity, moisture, sulfur content and other factors to ensure the quality and yield of n-hexane.

3. reaction principle

the production of n-hexane is mainly achieved by the dehydrogenation reaction of alkanes. The specific reaction principle is as follows:

C6H14 → C6H12 H2

n-hexane dehydrogenation reaction occurs under the action of high temperature and catalyst to generate n-hexene and hydrogen. The dehydrogenation reaction is an endothermic reaction that requires heat and the action of a catalyst to proceed.

4. Process
The manufacturing process of
n-hexane mainly includes the following steps:

1. Raw material pretreatment: the raw material for desulfurization, dehydration and other treatment, in order to ensure the smooth progress of the reaction.
2. Reaction: The pretreated raw material is heated to a certain temperature, and a catalyst is added to carry out dehydrogenation reaction.
3. Separation: The n-hexene and hydrogen generated by the reaction are separated to obtain n-hexene with higher purity.
4. Refining: Refining the separated n-hexene to remove impurities and obtain qualified n-hexane product.

5. equipment selection

In the manufacturing process of n-hexane, it is necessary to use heating furnace, reactor, separation tower, refining tower and other equipment. When selecting equipment, it is necessary to select the appropriate equipment model and material according to the requirements of the production process to ensure the reliability and stability of the equipment.
Precautions for
6.

In the manufacturing process of n-hexane, the following matters need to be paid attention to:

1. Strictly control the reaction temperature and pressure to avoid abnormal conditions during the reaction.
2. Replace the catalyst regularly to ensure the smooth progress of the reaction.
3. Strengthen the maintenance and maintenance of equipment to ensure the normal operation of equipment.
4. Pay attention to safe production, abide by relevant regulations and standards, and ensure the safety of employees and enterprises.

7. conclusion

n-hexane as an important chemical raw material, its manufacturing method has been widely concerned and studied. The quality and yield of n-hexane can be effectively improved by selecting suitable raw materials, mastering the reaction principle, optimizing the process flow and selecting suitable equipment, and creating greater economic and social benefits for enterprises.
