Octabenzone Chemical Properties,Uses,Production

Description

Octabenzone is a UV absorber/screener. It is used to protect polymers (e.g., polyethylene, polypropylene, polyvinylchloride) against damage by UV light. Colorless crystals; Light yellow powder.
Stable under recommended storage conditions.

Uses

Adsorbents and absorbents;
Paint additives and coating additives not described by other categories
Processing aids, not otherwise listed
Air Care Products
Building/Construction Materials not covered elsewhere
Fabric, Textile, and Leather Products not covered elsewhere
Furniture and Furnishings not covered elsewhere
Paints and Coatings
Plastic and Rubber Products not covered elsewhere

Analytic Laboratory Methods

Migration of photo stabilizers from plastics was studied in model elution expt where the plastics were placed at different temp 20 and 45 degree in different solvents, e.g. H2O, acetic acid,  sunflower oil, heptane, and the amt of photostabilizer eluted was determined by spectrophotometry and by gas chromatography. The elution of 2-hydroxy-4-n-octyloxybenzophenone depended on the type of plastic. Elution was low in polystyrene and high in polyolefins, polyethylene. Food contamination from these plastic additives is discussed.

Description

Octabenzone appears as light yellow/yellowish crystals/fine powder and is odourless and freely soluble in benzene, n-hexane, and acetone; slightly soluble in ethanol; and very slightly soluble in ethane dichloride. Octabenzone is a light stabiliser with good performance, capable of absorbing the UV radiation of 240–340 nm wavelength with the characteristics of light colour, non-toxicity, good compatibility, small mobility, easy processing, etc. Octabenzone protects the polymer to its maximum extent and helps to reduce its colour. It can also delay the yellowing and impede the loss of its physical function. Industrial applications of octabenzone is very extensive and applied to PE, PVC, PP, PS, PC, organic glass, polypropylene fibre, ethylene-vinyl acetate, etc. Also, octabenzone has very good light-stability effect on drying phenol aldehyde, varnish of alcohol and acname, polyurethane, acrylate, expoxnamee, etc. The major uses include UV stabiliser, for example, polyethylene and polypropylene fibres.

Chemical Properties

Light yellow powder

Uses

To stabilize polyethylene against deterioration by ultraviolet light.
