Difference Between Benzaldehyde and Benzophenone

Thekey differencebetween benzaldehyde and benzophenone is thatbenzaldehyde is analdehyde，而苯甲酮是ketone.

Both benzaldehyde and benzophenone are aromaticcarbonylcompounds. However, benzaldehyde has onephenylgroup attached to the carbonyl group because the other side of this carbonyl carbon has a hydrogen atom since it is an aldehyde. But, in benzophenone, both sides of the carbonyl carbon have phenyl groups.

What is Benzaldehyde?

苯甲醛是具有化学配方C的芳香醛₆H₅CHO. It has a phenyl group attached to an aldehyde functional group. Moreover, it is the simplest aromatic aldehyde. It occurs as a colourless liquid and has an almond-like characteristic odour. Also, its molar mass is 106.12 g/mol. And, its melting point is -57.12 °C while the boiling point is 178.1 °C.

Concerning the production of benzaldehyde, the main routes of the production of this compound are liquid phase chlorination and oxidation of toluene. However, this compound also occurs naturally in many foods as well; for example, in almonds. Therefore, one of the major uses of this compound is its use as an almond flavour in foods and scented products.

What is Benzophenone?

Benzophenone is an aromatic ketone having the chemical formula C13H10O. It is an aromatic ketone and has two benzene rings attached to the same carbon atom of the carbonyl group. We can abbreviate it as Ph2O where Ph refers to “phenol” (another name for benzene ring).

看着苯甲酮的性质,其摩尔ar mass is 182.22 g/mol. It has a Geranium-like odour, and it occurs as a white solid at standard temperature and pressure. Moreover, this compound is insoluble in water but, soluble in some organic solvents. The melting point is 48.5 °C while the boiling point is 305.4 °C. Besides, we can produce this compound via the copper-catalyzed oxidation of diphenylmethane with air.

在考虑苯甲酮的用途时，它可作为合成许多有机化合物的构建块，作为紫外线固化应用中的照片引导剂，作为塑料包装的紫外线阻滞剂，等等。

What is the Difference Between Benzaldehyde and Benzophenone?

苯甲醛是具有化学配方C的芳香醛₆H₅CHO while Benzophenone is an aromatic ketone having the chemical formula C₁₃H₁₀O. So, the key difference between benzaldehyde and benzophenone is that the benzaldehyde is an aldehyde, whereas the benzophenone is a ketone. Furthermore, benzaldehyde has an almond-like characteristic odour, but benzophenone has a geranium-like odour.

Moreover, when considering the chemical structures of these compounds, the difference between benzaldehyde and benzophenone is that the benzaldehyde has a phenyl group attached to an aldehyde functional group, whereas the benzophenone has two phenyl groups attached to both sides of carbonyl carbon.

Below infographic shows more comparisons regarding the difference between benzaldehyde and benzophenone.

概括– Benzaldehyde vs Benzophenone

苯甲醛是具有化学配方C的芳香醛₆H₅CHO while Benzophenone is an aromatic ketone having the chemical formula C₁₃H₁₀O. In summary, the key difference between benzaldehyde and benzophenone is that benzaldehyde is an aldehyde, whereas benzophenone is a ketone.
