Picolinic acid → 2-Pyridinecarboxylic acid, sodium salt (1:1)

Participants

Reaction Steps

An aqueous solution of sodium picolinate was prepared from 12.3 grams (100 mmol) of picolinic acid, about 4 grams of sodium hydroxide, and 50 ml of water while adjusting the solution to pH 7.2 with an amount of NaOH. With stirring, 2.84 grams (25 mmol of Zn2+) of basic zinc carbonate, 3Zn(OH)2.2ZnCO3.H2O was added to the solution. The resulting mixture indicated pH 13.8.
