What is the difference between acetone and phenylacetone

Related to question fields

1. Do you know the difference between acetone and phenylacetone?
2. This article will provide a detailed analysis of the differences between acetone and phenylacetone to help you better understand these two important compounds.

1. acetone structure and molecular formula

Acetone (Propanone) is a binary ketone compound with the molecular formula Celevated. Its structure is composed of three carbon atoms, the middle carbon is connected to two hydroxyl groups (-OH) and a methyl group (-CH), forming a typical ketone structure. Acetone has a molecular weight of 58.08g/mol, a melting point of 106°C and a boiling point of 81.5°C.

In contrast, phenylacetone (Benzyl acetone) is a ketone compound with an aromatic group, and the molecular formula is C≡H≡O₂. Its structure consists of a benzene ring (C-HLY1) and an acetyl group (-COCH₂-), forming a complex molecular structure. The molecular weight of propiophenone is 166.18g/mol, the melting point is 125°C, and the boiling point is 182.5°C.

2. physical property differences

1. Boiling point: The boiling point of acetone is 81.5°C, while the boiling point of phenylacetone is as high as 182.5°C. This means that phenylacetone is more volatile at high temperatures, while acetone is volatile in milder environments.

2. Density: Acetone has a density of 0.785g/cm³, while phenylacetone has a density of 1.030g/cm³. This indicates that the phenylacetone weighs more at the same volume.

3. Solubility: acetone has low solubility in water, but is well soluble with many organic solvents. Phenylacetone is less soluble in water, but is more active in organic solvents, especially in aromatic solvents.

3. main uses differ

1. Application of acetone: Acetone is an important binary ketone compound, which is widely used in organic synthesis. It is used as an intermediate in chemical synthesis, in esterification reactions, transesterification reactions and as a solvent. Acetone is also used in the manufacture of solvents, surface treatment agents and plastic additives.

2. Application of phenylacetone: Phenylacetone is often used in spices and food additives due to its aromatic odor. It is also used as an ingredient in paints and inks, with good antimicrobial and antioxidant properties. In the pharmaceutical field, phenylacetone is also used as an intermediate for certain drugs.

Comparison of 4. application scenarios

In practical applications, the application scenarios of acetone and phenylacetone have different emphases. For example, in the field of fine chemicals, acetone is used as an important raw material for organic synthesis because of its simple structure and high reactivity. In the food and spice industry, phenylacetone has become an important raw material for the development of new products because of its unique aroma and wide range of uses.

5. summary

Acetone and phenylacetone, as ketones, play an important role in chemical industry and related fields, despite their significant differences in molecular structure, physical properties and uses. Understanding their differences can help to better select the appropriate compounds for specific industrial applications.
