In a 500 ml-three-necked flask 4.8 g (0.01 mole) of the 2-chloro-4,6-dilauroxy-s-triazine prepared above, were mixed with 2.6 g (0.01 mole) of 2,6-diphenyl hydroquinone. After rinsing with nitrogen, 150 ml of acetone were added, followed by adding dropwise, with vigorous stilling, 0.4 g (0.01 mole) of NaOH dissolved in 7 ml of water, at 20° C. The solution then assumed an orange-yellow color, which largely disappeared upon heating the reaction mixture for a longth of time under reflux. After completion of the reaction, the contents of the flask were poured into 100 ml of ice water containing 2 ml of hydrochloric acid. The organic layer was extracted three times with methylene chloride, after which the combined extracts were washed and dried. After concentration of the organic layer by evaporation a product was obtained which crystallized out after a length of time (melting point 18°-20° C.).
