Octabenzone Chemical Properties,Uses,Production
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.
Preparation
Preparation by reaction of n-octyl chloride with 2,4-di-hydroxybenzophenone,
in the presence of a mixture of sodium carbonate, triethylamine and potassium iodide in refluxing butanol for 15 h (90%);
in the presence of potassium carbonate in cyclohexanone at 145° for 5 h (66%);
in the presence of potassium hydroxide and antimony triiodide in diethylene glycol at 150° for 1 h (93%);
in the presence of sodium bicarbonate and potassium iodide in 1-methylpyrrolidone for 2 h at 150° (96%).
General Description
2-Hydroxy-4-(octyloxy)benzophenone (HOBP) is a UV based absorber that has 2-hydroxybenzophenone as a functional group. It can be used to enhance the light fastness of polymers using UV absorbers with sulfur and phosphorus compounds.
