The conditions of hydrolysis and lactonization of the calcium and sodium salts of pantothenic and pantoic acids have been studied.The selected conditions of hydrolysis (t = 80 deg C, CHCl = 13percent) led to a 100percent yield of β-alanine and pantothenates after 60 min from the beginning of hydrolysis, while the formation of pantolactone was complete in 105 min for the calcium salt and in 75 min for the sodium salt.The hydrolysis and lactonization reactions have been performed under the conditions mentioned, and the GLC of the pantolactone formed has permitted the determination of various concentrations of calcium pantothenate.The results obtained from the GLC analysis of pantolactone indicate the possibility of a quantitative determination of salts of pantothenic and pantoic acids.The sensitivity of this method is 0.2-5 nmole.
