Tert-butylphenol is an organic compound that is a molecule consisting of a benzene ring and a t-butyl group. In industry, tert-butyl phenol is widely used in the production of pharmaceuticals, dyes and other chemical products. This paper will focus on the production process and preparation method of tert-butyl phenol.

1. production process
There are two main production processes for
tert-butylphenol, one is prepared by solvent extraction method, and the other is prepared by recombination method. Among them, the solvent extraction method is the most widely used method for preparing tert-butylphenol in industry.

1. Solvent extraction method

solvent extraction method is the use of organic solvents to separate the product from the reactants. This method is suitable for moderate production because the equipment required for this method is relatively simple and the process flow is simpler than that of the reconstitution method.

The specific operation procedure of the method is as follows: The first step of the

is to preheat phenol, tert-butyl alcohol and waste water. The second step of the

: the reactant is added to the reaction kettle, and the reaction catalyst is added and stirred to allow the reaction to proceed.

Third Step: The reaction mixture is fed to an extraction column and the product is isolated from the reaction mixture using an organic solvent. The fourth step of the

: the resulting product is collected and then subjected to subsequent treatment.

the advantages of this method are fast reaction speed, convenient operation and low cost, so it is widely used in industrial production.

2. Recombination Method

Recombination method is a method for producing tert-butylphenol by catalyzing the reaction of phenol and tert-butanol in the reaction wastewater with a catalyst. This method is more suitable for small volume production and requires more complex equipment than solvent extraction.

The specific operation procedure of the method is as follows: The first step of the

: phenol and tert-butyl alcohol are added into the reaction kettle together with the reaction wastewater.

Second Step: A catalyst is added to the reaction wastewater and stirred to allow the reaction to proceed. The third step of the

: the reaction mixture is subjected to rectification and the product is isolated. The fourth step of the

: the resulting product is collected and then subjected to subsequent treatment.
the advantage of
this method is that it can realize continuous production of products, but the disadvantage is that the equipment and process are relatively complicated, and the cost is relatively high.

2. Preparation Methods

In addition to industrial production, tert-butylphenol can also be prepared by laboratory synthetic methods. The following are some laboratory synthesis methods of tert-butyl phenol:

1. Preparation of tert-butyl phenol by acid-catalyzed reaction

Mix tert-butyl alcohol and phenol evenly, and then under the action of hydrochloric acid catalyst, Make them undergo acid-catalyzed reaction. This reaction forms tert-butylphenol in the reaction mixture.

reaction equation is as follows:

C6H5OH (CH3)3COH → C6H5OC(CH3)3 H2O

2. Preparation of tert-butylphenol by iodination reaction
