Abstract

See full text

A method for quantification of the amount of impurities in lactide. The method is characterized in that the quantification of the impurities is based on measurements performed on absorptions in the near Infra-Red region of the electromagnetic spectrum. With this method, small amounts of impurities like water, free-acid species or both can be determined online in a reaction mixture of lactide in a relatively simple manner. This allows a simple online monitoring of the production process of lactide.
