Glycolic, lactic and 2-hydroxybutanoic acids are partly converted to various condensation products during heating.This conversion was studied at 100 deg C and 125 deg C by identifying the trimethylsilylated products consisted of both linear (dimers and trimers) and cyclic (dimers) structures.The influence of the condensation on the recovery and purification of the hydroxy acids by distillation is discussed.
