2,4-Dihydroxybenzophenone powder Raw Materials CAS 131-56-6
Product Overview:
2,4-Dihydroxybenzophenone powder, also known as Octocrilene, is a commonly used sunscreen. It can effectively absorb ultraviolet A band (UVA) and B band (UVB). 2,4-Dihydroxybenzophenone is a commonly used organic UV absorber. It is a colorless crystalline powder with good thermal and light stability. 2,4-Dihydroxybenzophenone has a high absorption capacity in the ultraviolet region (200-400 nm wavelength) and is able to effectively absorb ultraviolet light, thereby protecting organic materials from ultraviolet light damage. 2,4-Dihydroxybenzophenone powder protects the stability and performance of organic materials by absorbing the energy of ultraviolet light, converting it into thermal energy and dispersing it for release. Its absorption peak is near 300 nanometers, and it can absorb most UV-B and part of UV-A radiation, which has A good protective effect on the material. 2,4-Dihydroxybenzophenone also has good solubility and compatibility and can be miscible with a variety of organic materials. It can be used in a variety of applications such as coatings, plastic products and rubber products to provide UV protection for these materials.

Applications/Functions of 2,4-Dihydroxybenzophenone powder
- 2, 4-dihydroxybenzophenone powder is used as an ultraviolet absorbent, and 2-hydroxy-4-methoxybenzophenone (UV-9), 2-hydroxy-4-octyloxybenzophenone (UV-531) and other benzophenones derived from this product. As well as other monohydroxyl, dihydroxyl, trihydroxyl, and tetrahydroxyl compounds are the most widely used absorbent light stabilizers.
- 2,4-Dihydroxybenzophenone is suitable for polyolefin, polyvinyl chloride and polystyrene
- 2,4-Dihydroxybenzophenone is mainly used in plastics and other as a light stabilizer, which can effectively protect organic glass and cloth, prevent data from deteriorating due to light, and is also used as an intermediate to synthesize other ultraviolet absorbers.
Physicochemical Property of 2,4-Dihydroxybenzophenone powder
Light yellow acicular crystal or white powder. Melting point 142.6-144.6℃. Solubility at 25℃ (g /100 ml solvent) : acetone >50, benzene 1, ethanol >50 water <0.5, n-heptane <0.5.
Production methodprocess of 2,4-Dihydroxybenzophenone powder
2- (2',4 '-dihydroxybenzophenone) benzoic acid was prepared by condensation of phthalic anhydride and resorcinol, and then 2, 4-dihydroxybenzophenone powder was obtained by dehydroxylation reaction.
