Reaction Steps

To a suspension of 20.7 parts (0.155 mole) of propyl p-hydroxybenzoate in 40 parts of water that had been cooled to 0°-10° C. was slowly added a 50% aqueous sodium hydroxide solution until the pH of the resulting solution was 11.9. A solution of 12.6 parts (0.06 mole) of zinc acetate dihydrate in 200 parts of water was added to the sodium salt solution. The white precipitate that formed was separated by filtration, washed with cold water, and dried. There was obtained 23.9 parts of zinc bis(propyl p-hydroxybenzoate).
