Ethyl phenylacetone is an important chemical raw material, widely used in medicine, cosmetics, spices and other fields. This article will introduce the manufacturing method of ethyl phenylacetone. The manufacturing method of
ethyl phenylacetone mainly includes the following steps:
First, phenylpropanol and ethyl chloride are reacted to form acetophenone and ethyl bromide. Then, ethyl bromide and bromine are reacted to form bromoethane and bromoacetaldehyde. Next, ethyl bromide and acetone are reacted to form bromoethyl acetone. Finally, ethyl bromoacetone and hydrogen are reacted to form ethyl phenylacetone.
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, attention needs to be paid to environmental protection to avoid pollution of the environment.
In addition, other methods can be used to manufacture ethyl phenylacetone. For example, phenylpropanol and sodium ethyl sulfate can be reacted to produce acetophenone and ethyl sulfuric acid. Then, the ethyl sulfuric acid and bromine are reacted to form bromoacetic acid and bromoacetaldehyde. Next, bromoacetic acid and acetone are reacted to form bromoethyl acetone. Finally, bromoethyl acetone is reacted with hydrogen to form ethyl propiophenone. Although this method is simple and easy to use, it requires strict control of the reaction conditions to ensure the purity of the product.
In conclusion, ethylpropiophenone is an important chemical raw material with various manufacturing methods. Regardless of which method is 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, it is also necessary to pay attention to environmental protection to avoid pollution of the environment.
