Ethyl Phenyl Ketone (EPK) is an important organic chemical raw material, which is widely used in medicine, pesticide, spice, plastic and other fields. In the field of chemical production raw materials, the upstream and downstream related products of ethyl acetophenone are very rich, and some of the main upstream and downstream products will be described in detail below.

1. upstream products

1. acetophenone: acetophenone is one of the main raw materials of ethyl acetophenone, through the reaction of benzene and ethyl acetoacetate in acidic catalyst.
2. Ethanol: Ethanol, as another raw material of ethyl acetophenone, is mainly derived from petrochemical or biological fermentation.

2. downstream products

1. Pharmaceutical intermediates: ethyl acetophenone can be used as intermediates for the synthesis of a variety of drugs, such as antidepressants, anti-inflammatory drugs, anti-tumor drugs, etc.
2. Pesticides: Ethyl acetophenone can be used to synthesize some pesticides, such as fungicides, insecticides, etc.
3. spices: ethyl acetophenone itself has a pleasant fragrance, can be used as spices for food, cosmetics and other industries.
4. Plastic additives: Ethyl acetophenone can be used as a plastic additive to improve the performance of plastics.

Specifically, downstream products of ethylacetophenone include, but are not limited to, the following:

1. α-Bromoacetophenone: prepared by the reaction of ethylacetophenone with bromine, which can be used to synthesize drugs and pesticides.
2. Phenylacetic acid: prepared by hydrogenation and reduction of ethyl acetophenone, which can be used for the synthesis of fragrances and pharmaceutical intermediates.
3. Phenylacetonitrile: prepared by the reaction of ethyl acetophenone with sodium cyanide, which can be used in the synthesis of pharmaceuticals and pesticides.
4. Ethyl styrene: prepared by decarbonylation of ethyl acetophenone and used in the synthesis of polymers and copolymers.

In short, as an important organic chemical raw material, ethyl acetophenone has a wide range of upstream and downstream related products, involving medicine, pesticides, spices, plastics and other fields.
