Manufacturing method
of mixed benzene
mixed benzene is an important raw material for chemical production, which is widely used in medicine, pesticide, dye, spice and other fields. This paper will introduce the manufacturing method of mixed benzene, including raw material selection, production process, equipment selection and so on.

1. raw material selection

mixed benzene manufacturing raw materials mainly include benzene, toluene, xylene and other aromatic hydrocarbon compounds. These compounds are liquid at room temperature and have high volatility and toxicity. Therefore, when selecting raw materials, it is necessary to consider its purity, quality stability and safety. At the same time, it is also necessary to select the appropriate raw material ratio according to the requirements of the production process.

2. production process

mixed benzene manufacturing process mainly includes mixing, distillation, separation and other steps. The specific process is as follows:

1. Mixing: Benzene, toluene, xylene and other raw materials are mixed together according to a certain proportion and stirred evenly.

2. Distillation: The mixed raw materials are heated and distilled to separate the light components and heavy components. The light components mainly include low boiling point compounds such as benzene, and the heavy components include high boiling point compounds such as xylene.

3. separation: through further separation operation, the light components and heavy components are collected separately to obtain mixed benzene products. In the production process of

, it is necessary to strictly control the process parameters to ensure product quality and production safety. At the same time, it is also necessary to carry out regular maintenance and maintenance of production equipment to ensure the normal operation and service life of the equipment.

3. equipment selection

In the production process of mixed benzene, it is necessary to use mixers, distillation columns, separators and other equipment. When selecting these equipment, it is necessary to consider comprehensively according to the requirements of the production process and the characteristics of the product. Specifically, it is necessary to consider the production capacity of the equipment, operating flexibility, energy consumption, safety and other factors. At the same time, it is also necessary to select the equipment according to the use and maintenance requirements to ensure the reliability and stability of the equipment.
Precautions for production of
4.

In the production process of mixed benzene, the following matters need to be paid attention to:

1. Strictly control the quality and purity of raw materials to ensure the stability of product quality.

2. Strengthen the safety management of the production site to prevent leakage, fire and other safety accidents.

3. Regular maintenance and maintenance of production equipment to ensure the normal operation and service life of the equipment.

4. Strengthen the monitoring and control of the production process, and discover and solve problems in the production process in time.

In short, the manufacturing method of mixed benzene needs to take into account the selection of raw materials, production processes, equipment selection and other aspects. In the production process, it is necessary to strictly control the process parameters and equipment operation to ensure product quality and production safety. At the same time, it is also necessary to strengthen the management and maintenance of the production site to improve production efficiency and economic benefits.
