4-(4-Acryloxy-butyl-1-oxy)-benzoic acid is a useful research chemical.

The preparation of 4-(4-acryloxy-butyl-1-oxy)-benzoic acid is as follows:In a Dean-Stark apparatus were added 4-(ω-hydroxybutoxy)benzoic acid (7.7 g, 0.037 mol), acrylic acid (23.0 g,0.324 mol) chloroform (150 mL), pTSA (1.5 g, 0.008 mol) and hydroquinone (1.5 g, 0.014 mol). The mixture was refluxed until the end of the reaction. After a standard workup procedure the product was recrystallizedfrom isopropanol. Yield 65%; 

Very soluble in N,N-Dimethylformamide,soluble in methanol,sparingly soluble inglacial acetic acid, very slightly soluble inchloroform.
