The manufacturing method
of coking phenol
1. Introduction

coking phenol is an important chemical production raw material, widely used in medicine, pesticides, plastics, spices and other fields. Therefore, it is of great significance to study the manufacturing method of coking phenol to improve the yield and quality of phenol, reduce production costs and promote the development of related industries. This paper will introduce a manufacturing method of coking phenol, which has the advantages of simple process, convenient operation and high yield.

2. Materials and Methods

1. Material

The raw materials required for this experiment are coke, benzene and air. Among them, coke is the carbon source, benzene is the hydrogen source, and air is the oxidant.

2. Equipment

The equipment required for this experiment includes coking furnace, reactor, condenser, separator, etc.

3. Manufacturing method

(1) After mixing coke and benzene in a certain proportion, it is added to the reactor.

(2), air is introduced into the reactor to control a certain temperature and pressure, so that coke and benzene are coking reaction. Coked phenol vapor and unreacted benzene vapor generated
the reaction of
(3) enter the condenser and are condensed to obtain a mixture of coked phenol and benzene. The mixture is fed to a separator

(4) and the pure coked phenol is separated.

3. results and discussion

1. Effect of temperature on the yield of coking phenol

experimental results show that the temperature has a greater impact on the yield of coking phenol. When the temperature is low, the coking reaction is incomplete and the yield is low; when the temperature is high, although the coking reaction is complete, more by-products will be produced, which affects the purity of coking phenol. Therefore, it is necessary to select an appropriate temperature to ensure the yield and purity of the coking phenol.

2. The effect of pressure on the yield of coking phenol

experimental results show that the pressure has little effect on the yield of coking phenol. In the appropriate pressure range, the yield of coking phenol increases with the increase of pressure, but when the pressure is too high, it will increase the energy consumption and operation difficulty of the equipment. Therefore, it is necessary to select the appropriate pressure according to the actual situation.

4. Conclusion

This study introduces a manufacturing method of coking phenol, which has the advantages of simple process, convenient operation and high yield. The experimental results show that the temperature and pressure have a certain effect on the yield of coking phenol, and it is necessary to select the appropriate temperature and pressure to ensure the yield and purity of coking phenol. This study provides a useful reference for the industrial production of coking phenol.
