It is a flavoring agent found in plants and fruits such as grapes. It is a chemical that increases sensitivity to light in the field of photochemistry.

It is also referred to as oxybenzone. It is an organic chemical. It exhibits a protective effect when chemicals used in the manufacture of many personal care and personal hygiene products in the cosmetics industry are exposed to sunlight over a certain period of time.

Its Other Names Are as Follows;

• Diphenylmethanone
• Diphenyl Ketone
• Benzoyl Benzene
• Diphenylketone
• a-oxodiphenylmethane
• a-oxoditane
• 131-57-7

How is Benzophenone-3 Produced?

There are several methods for the production of Benzophenone-3.

1. In the 1st method, the condensation of Benzyl Chloride and Benzene is carried out. In the subsequent process, oxidation is performed with Nitric Acid.
2. In the 2nd method, Carbon Tetrachloride is reacted with benzene, followed by hydrolysis to achieve condensation.
3. In the 3rd production method, it is obtained by the condensation of benzoyl chloride and Benzene in the presence of Aluminum chloride and crystallization with ethanol.

What are the Physical and Chemical Properties?

It is in the form of white solid crystals with a floral scent. It has a smell similar to roses.

The boiling point is 305 °C.

The melting point is 47.8 °C.

Benzophenone-3 has no solubility in water. It is soluble in organic solvents.

By its nature, it is highly soluble in acetic acid, acetone, and carbon disulfide. It has moderate solubility in Methanol and benzene.

Its density is 1.4 g/cm³.

What are the Usage Areas of Benzophenone-3?

• Soaps, which are general cleaning products, undergo deterioration in scent and color when exposed to sunlight. In this field, Benzophenone-3 is used to prevent the degradation of substances exposed to UV light.
• Its derivatives used in organic synthesis are used as polymerization inhibitors for styrene.
• It is used as an additive in adhesive and plastic coating formulations.
• It is used in the manufacture of varnishes, paints, and polishes.
• It is used to bind monosaccharides in environments where polysaccharides are present.
• It has capabilities such as flavor enhancement in the manufacture of foods.
• It can be used in the manufacture of printing inks that undergo curing in the presence of ultraviolet light.

What Factors Affect Its Prices?

The price of Benzophenone-3 is directly dependent on the prices of the chemicals used in its production. As benzene prices increase, the prices of this raw material will increase.

Prices depend on the stocks of companies selling Benzophenone-3. As stocks increase, prices will decrease.
