D-lactic acid with a monocarboxylic typical chemical properties

D-lactic acid with a monocarboxylic typical chemical properties of a weak acid solution, the concentration of more than 50% portion is formed when milk Calcium lactate  the reaction of alcohols with some alkyd resin, the heating conditions can be intermolecular potassium lactate  to form lactic acid lactylate (C6H10O5), heating may be further diluted and hydrolyzed to D-lactic acid. Role of zinc oxide in the dehydrating agent, the removal of two molecules of two molecules of D-lactic acid in water, to form a cyclic dimer from poly D-lactide (C6H8O4, DLA). Sufficiently dehydrated D-lactic acid polymer can be formed. The more concentrated the acid esterification stronger the trend itself, thus lactic acid and lactic acid is typically a mixture of lactide.
