There are many methods for synthesizing 4- (4-hydroxyphenoxy) phenol, each with its own advantages and disadvantages. The following is the detailed description of Jun.
One is the nucleophilic substitution method. This is a classic method. Halogenated benzene and phenol salts are used as raw materials. In an alkaline environment, the nucleophilic substitution reaction occurs between the two to generate the target product. Its advantages are that the raw materials are common, easy to obtain, the reaction conditions are mild, the operation is convenient, the yield is not high, and there are many side reactions. The separation and purification of the product is quite cumbersome.
Second, the rearrangement reaction method. A specific phenol ester is used as the starting material and is skillfully converted into the target product through the rearrangement reaction. The advantage of this method is that the atomic economy is good, the yield is high, and the generation of waste can be effectively reduced. However, it requires strict reaction conditions, requires specific catalysts, and the cost of catalysts is quite high. It also has high requirements for reaction equipment, which greatly increases the production cost.
Third, oxidative coupling method. With the help of oxidative coupling reaction of phenolic compounds, the synthesis of the target product can be achieved. This method has simple steps, high reaction efficiency, and can achieve large-scale production. However, the reaction requires the use of strong oxidants, which is not safe, and also pollutes the environment to a certain extent, and subsequent treatment is quite difficult.
Fourth, catalytic hydrogenation method. The target product is obtained by catalytic hydrogenation and reduction of phenol derivatives containing nitro groups as raw materials. This method has high selectivity, good product purity and little environmental pollution. However, it requires extremely high catalyst performance, and the reaction needs to be carried out in a high-pressure environment, which requires strict equipment and huge investment costs.
The above synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively consider many factors such as raw material cost, reaction conditions, product quality, environmental impact and production cost, and carefully select the appropriate synthesis method to achieve the goal of efficient, green and economical synthesis.
