Versuchsvorschrift

NMR spectrum of the product was consistent for a monolactate salt of m-AMSA containing 0.6 mole of acetone per mole of salt. The product contained as an impurity approximately 0.1 mole % of lactyl lactate salt which is formed due to the presence of up to 20% of lactyl lactic acid in ACS purity DL-lactic acid.*
