coarse fritted glass filter and the filter cake zinc sludge washed with 100 ml of 5 sodium hydroxide solution the collected filtrates dark green in color were transferred to a two liter beaker kept at a temperature below 10 u00b0 c and slowly neutralized with 6n hydrochloric acid a brown solid was obtained which was collected by filtration yield 93 the compound was extracted with benzene or acetone benzene 1 3 for 48 hours a light brown solid was recovered after the evaporation of the solvent yield 80 further purification by recrystallization from ethanol gave an off white solid m p 187 u00b0 189 u00b0 c a 100 ml 3 neck round bottom flask was charged with a 5 24 g 0 02 mole glycidyl methacrylate 3 0 ml 0 22 mole tetra butyl ammonium bromide tbabr 0 4 g 1 2 mole and anhydrous toluene 30 ml while the entire system was under an atmosphere of dry nitrogen a trace amount of hydroquinone was also added the contents of the flask were heated under gentle reflux for 24 hours after the reaction was complete the mixture was allowed to cool to room temperature the solution was filtered diluted with additional toluene 50 ml washed 3 times with saturated sodium chloride solution once with water and dried over anhydrous magnesium sulfate after filtration the solvent was evaporated and the crude oily solid which was obtained in essentially quantitative yield was.
