4-Dodecyloxy-2-hydroxybenzophenone Usage And Synthesis

Application

UV-1200, an ultraviolet absorber, is a replacement for UV-531 and UV-9. This product is non-toxic, non-flammable, non-explosive, non-corrosive, and exhibits good storage stability. It absorbs 270-340nm ultraviolet light, preventing photo-aging, cracking, and embrittlement of polymer materials, thus significantly extending their service life. Due to its superior performance, it is widely used abroad in polyethylene, polypropylene, acrylic fibers, various high-grade coatings, and automotive paints.

Preparation

Preparation by reaction of 1-bromododecane (dodecyl bromide or lauryl bromide) with resbenzophenone in the presence of potassium carbonate in refluxing acetone for 16 h or for 20 h.

Purification Methods

Recrystallise it from n-hexane and then 10% (v/v) EtOH in acetonitrile [Valenty et al. J Am Chem Soc 106 6155 1984].
