Participants

Reaction Steps

To a suspension of 17.5 parts (0.115 mole) of methyl p-hydroxybenzoate in 40 grams 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 12. 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 19.2 parts of zinc bis(methyl p-hydroxybenzoate).
