The manufacturing method
of medium temperature coal tar
1. Introduction

With the rapid development of the chemical industry, medium temperature coal tar as an important chemical production raw material, its manufacturing method has attracted much attention. Medium temperature coal tar has unique physical and chemical properties, and is widely used in plastics, rubber, paint, medicine and other fields. This article will introduce the manufacturing method of medium temperature coal tar in detail, aiming to provide readers with a comprehensive and in-depth understanding.

2. Raw materials and equipment

1. Raw materials: The raw materials for the manufacture of medium-temperature coal tar are mainly coal tar, and its quality should meet relevant industry standards.
2. Equipment: The main equipment includes reaction kettle, heater, agitator, condenser, storage tank, etc.

3. manufacturing steps

1 ingredients: according to a certain proportion of coal tar and other additives into the reactor.
2. Heating and stirring: turn on the heater, heat the materials in the reactor to a certain temperature, and start the stirrer at the same time to ensure that the materials are fully mixed.
3. Reaction: Keep stirring at the specified temperature and time to make the materials fully react.
4. Cooling and separation: After the reaction is completed, the heating is stopped, the materials in the reaction kettle are naturally cooled, and separated by a condenser.
5. Storage: Store the separated medium temperature coal tar in a storage tank for further processing.

4. Precautions

1. Strictly control the quality of raw materials to ensure that coal tar meets relevant standards.
2. During the heating and stirring process, keep the temperature and stirring speed stable so as not to affect the product quality.
3. During the reaction process, pay close attention to the changes of the materials in the reaction kettle. If there is any abnormal situation, measures should be taken in time.
4. During the cooling and separation process, ensure that the condenser works normally to ensure the purity of the product.

5. quality inspection
After the
is manufactured, it is necessary to carry out quality inspection on medium temperature coal tar, including density, viscosity, flash point, acid value, moisture and other indicators. Ensure product quality meets relevant standards and customer requirements.

6. waste treatment
The waste generated in the
manufacturing process shall be properly treated in accordance with environmental protection requirements to avoid environmental pollution.

7. conclusion The manufacturing method of

medium temperature coal tar involves many links and precautions. In order to ensure product quality and environmental protection requirements, it is necessary to strictly control the quality of raw materials, equipment operation, manufacturing process and quality inspection. Through the introduction of this paper, we hope to provide readers with a comprehensive and in-depth understanding, and provide reference for the manufacture of medium temperature coal tar. At the same time, with the continuous development of chemical technology, the manufacturing method of medium temperature coal tar may be improved and optimized in the future, and it is necessary to continue to pay attention to the industry dynamics and technological progress.
