Procedure

Hydroxyoctyl methacrylate (HOMA) is prepared by reacting 28.8 parts of methacrylic acid with 40.0 parts 1,2-epoxyoctane in the presence of 0.07 parts of tetramethylammonium chloride and 0.21 parts of hydroquinone monomethylether for 4 hours at 140° C. with O2 bubbled through the reaction mixture. The product is distilled at 95°-110° C./0.4 mm to yield 46 grams of HOMA which was identified by IR and NMR.
