1 3-Diphenyl-1 3-Propanedione CAS No 120-46-7

Dibenzoyl Methane Dbm (also known as 1,3-diphenyl-1,3-propanedione, English name is Dibenzoyl Methane, abbreviated as DBM) is an important β-diketone structure thermoplastic for light Stabilizer, heat stabilizer, non-toxic, odorless, white or light yellow crystalline powder, widely used in polyvinyl chloride (PVC) plastic and acrylonitrile-butadiene-styrene (ABS) resin, as plastic processed products A new type of auxiliary stabilizer, easily soluble in ether, chloroform, xylene, toluene and sodium hydroxide aqueous solution, slightly soluble in ethanol, very slightly soluble in water.
use
1. Pvc Heat Stabilizer Dibenzoylmethane can absorb ultraviolet light above 290nm, has high light transmittance, is non-toxic and tasteless. Diybenzoyl Methane (DBM) can be used together with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers to improve the initial coloration of PVC. Performance, transparency and long-term stability, effectively improve the "zinc burning" phenomenon in the processing of PVC products, promote the replacement of calcium/zinc composite stabilizers, and are widely used in the manufacture of PVC mineral water bottles, infusion sets, infusion tubes, children's Non-toxic transparent PVC products such as toys and other medical, food packaging.
2. Used for analytical reagents, determination of carbon disulfide and thallium, gravimetric determination of uranium, photometric determination of U+4, extraction of silver, aluminum, barium, etc.
3. Widely used in the synthesis of high-efficiency herbicides, the synthesis of ultraviolet absorbers, cosmetic sunscreens, and the synthesis of high-efficiency rare earth organic complex fluorescent materials.
