Acrylic acid and styrene are two common chemicals widely used in industry and daily life. They have different characteristics and application areas, and the following will introduce their differences in detail

1、 Chemical structure: The chemical formula of acrylic acid is CH2=CHCOOH, which is a colorless liquid. The chemical formula of styrene is C6H5CH=CH2, which is a colorless liquid or white crystal. From a chemical structure perspective, there is a significant difference between acrylic acid and styrene

2、 Physical properties: 

1 Acrylic acid has an irritating odor, a low density, a melting point of 14 ℃, and a boiling point of 141 ℃. It is soluble in water and can react with various organic substances to form polymers

2. Styrene has a fragrant odor and a high density, with a melting point of 31 ℃ and a boiling point of 145 ℃. It has a low solubility in water and can undergo addition reactions with many substances, generating various organic compounds

3、 Application field: 

1 Acrylic acid is widely used in fields such as construction, textiles, and pharmaceuticals. It can be used as a basic chemical for synthesizing acrylic resin, polypropylene, etc. Acrylic acid can also be used to prepare products such as dyes, coatings, and plastics

2. Styrene is mainly used to synthesize polystyrene PS, which is a common plastic raw material. Polystyrene has good impact resistance and transparency, and is widely used in fields such as electronics, packaging, and construction

4、 Environmental impact: 

1 Acrylic acid has certain toxicity and may cause certain harm to the environment. However, acrylic acid can be completely polymerized in some polymerization reactions, reducing its environmental risk

2. Styrene may release volatile organic compounds during production and use, which can have certain impacts on the environment and human health. Therefore, it is necessary to pay attention to environmental protection and safety when using styrene

In summary, there are significant differences between acrylic acid and styrene in terms of chemical structure, physical properties, application fields, and environmental impact. In practical applications, we need to choose suitable chemicals based on specific needs to ensure safety and environmental protection in production and daily life
