Ethyl benzene acetone is an important chemical raw material, which is widely used in medicine, cosmetics, spices and other fields. This article will introduce the manufacturing method of ethyl benzene acetone. The method for producing
ethylpropionic acid mainly includes the following steps:
First, phenylpropanediol and ethyl chloride are reacted to produce acetophenone and ethyl bromide. Then, ethyl bromide and bromine are reacted to produce bromoethane and bromoacetaldehyde. Next, bromoethane and acetone are reacted to produce bromoethyl acetone. Finally, bromoethylacetone and hydrogen are reacted to produce ethylphenylacetone. It should
be noted that in the process of manufacturing ethylpropiophenone, the reaction conditions need to be strictly controlled to ensure the completeness of the reaction and the purity of the product. In addition, it is necessary to pay attention to environmental protection to avoid environmental pollution.
In addition, other methods can also be used to produce ethylpropiophenone. For example, phenylpropyl alcohol and sodium ethyl sulfate can be reacted to produce acetophenone and ethyl sulfate. Then, ethyl sulfuric acid and bromine are reacted to produce bromoacetic acid and bromoacetaldehyde. Next, bromoacetic acid and acetone are reacted to produce bromoethylacetone. Finally, bromoethylacetone and hydrogen are reacted to produce ethylphenylacetone. Although this method is simple and easy, it needs to strictly control the reaction conditions to ensure the purity of the product.
In short, ethyl benzene acetone is an important chemical raw material, and its manufacturing methods are diverse. Regardless of the method used, the reaction conditions need to be strictly controlled to ensure the completeness of the reaction and the purity of the product. At the same time, we also need to pay attention to environmental protection to avoid environmental pollution.
