Difference Between Acetone and Benzaldehyde (With Table)

Chemicals are mixed with our daily life. From agriculture to face products, everything is chemicals now. It is essential to know about what we are using day today. Acetone and benzaldehyde are two different chemical forms found in the human body.

Acetone vs Benzaldehyde

The difference between acetone and benzaldehyde is their melting point. The melting point of acetone is -95 degrees celsius, and the melting point of benzaldehyde is -57 degrees celsius. Acetone befalls as a breakdown product from metabolism, whereas benzaldehyde occurs in human urine. The molecular weight of acetone is 58.08 g/mol and for benzaldehyde 106.124g/mol. Acetone occurs in vehicles and cosmetics, and benzaldehyde occurs in pharmaceuticals and perfumes.

Acetone is a breakdown product of a chemical compound. It is a colorless volatile liquid. Acetone is the simplest ketone. “C3H6O” is the chemical formula of acetone. Compared to water, acetone is less dense. The density of acetone in water is around 0.8. The vapors in acetone are heavier than air, and it is around2.0. Since it is less dense than water, it can easily dissolve in the water. Both the polar and non-polar substances are get dissolved.

Benzaldehyde is an oily yellow substance. It has an almond odor. Benzaldehyde is made of a single formyl group that gives aromatic aldehyde. Cherries, peaches have the chemical form of benzaldehyde. It is often found in human urine. C6H5CHO is the chemical formula of benzaldehyde. It is a hazardous chemical form when you inhaled or swallowed. Sometimes it may cause eye irritation, and eye-related problems may occur for people who work with benzaldehyde.

What is Acetone?

Acetone is a chemical form with one important peculiarity of accumulating in the human body. By accumulating increases the concentration of the human body. If the accumulation crosses the limit then chronic poison is also occurring. When metabolism fat is broken acetone is produced in the human body. Acetones occur in volcanic gases, plants, animals, and forest fires. Acetone is a simple ketone chemical form.

Acetone is also found in human urine and blood. The carbohydrate settled in the body gets depleted when you are fasting or on diet. This results in the production of acetone in the stomach and causes acetone breath. Diabetes patients have more amount of acetone in their urine and blood. The increase in acetone in the body cause ketoacidosis settlement that is a symptom of diabetes. It easily accumulates in the body results in an increase in concentration.

Acetone is soluble in water easily and acts as a solvent. Acetone is also s drying agent in protein precipitation. Sometimes it is a medical agent in cosmetics. Acetone is added to food for addicts and for coloring agents. It is mainly used in acne treatment for peeling the skin. It is also a primary part of cleaning agents. Acetone is less dense in water and denser in air. The acetone vapors are more hazardous. Acetone has narcotic effects that affect the nervous system.

What is Benzaldehyde?

Benzaldehyde is a reactive liquid. It is a colorless liquid and then changes to yellow color. The boiling point of benzaldehyde is 178.7°C. It is insoluble in water and soluble in liquid ammonia. Benzaldehyde causes severe irritation with prolonged contact. Benzaldehyde is also used in water treatment and fuel additives. It is a major compound in beer repellent. It is simply called a chemical flavor.

In 1803, benzaldehyde was first extracted by a French pharmacist. Nature benzaldehyde is the poisonous material in almonds. Friedrich Wohler and Justus von Liebig first synthesized benzaldehyde in 1832. Near honeycombs, benzaldehyde solutions are found. Cigarette pods contain benzaldehyde as a flavor. Since it is a reactive liquid the concentration is comparatively low. Benzaldehyde is also added in cool mint flavors.

Some flavored foods contain benzaldehyde. Cosmetic and Pharmaceuticals products also contain benzaldehyde. Benzaldehyde is the chief agent in industrial things of organic compounds. In malachite green dye and dimethylaniline contain benzaldehyde. In acridine dyes, it is the precursor. Sometimes benzaldehyde is converted into derivatives for aldol condensations. By adding hydrochloric acid with benzaldehyde mandelic acid is prepared.

Main Differences Between Acetone and Benzaldehyde

  1. Acetone is a stable liquid in recommended storage space, and benzaldehyde is a reactive liquid.
  2. Acetone is auto ignited at 465 degrees celsius, and benzaldehyde is auto ignited at 192 degrees celsius.
  3. Acetone is soluble in water, and benzaldehyde is not soluble in water.
  4. The boiling point of acetone is 56 degrees celsius, and the boiling point of benzaldehyde is 178.7 degrees celsius.
  5. The density of acetone in water is 0.8, and the density of benzaldehyde in water is 1.05.


Acetone and benzaldehyde are two different chemical forms. They are found in the human body. Acetone produces when fat metabolism gets broken, and benzaldehyde is found in the human urine. Acetone occurs in plants and vehicles. Benzaldehyde occurs in the stones of almonds. Acetone is mainly used as a solvent and it is easily soluble in water. Benzaldehyde is mainly used in chemical factories to add flavors and smell to products. Acetone is also used in the medical and cosmetic industries. Benzaldehyde is also used in the preparation of alkaline and the production of fuel. Acetone is a transparent liquid, whereas benzaldehyde is a colorless to yellow liquid.
