Abstract

Lactulose is industrially produced by the homogeneous alkali catalysed isomerisation of lactose. The use of heterogeneous alkaline ion-exchangers as catalyst can result in a simpler overall process and in higher selectivities.

The effect of the type of ion-exchanger, particle diameter, temperature and sugar concentration on the kinetics has been studied. A kinetic model is given which can be used to describe the experimental results. Loss of selectivity can occur due to a limiting diffusion rate. High sugar concentrations are beneficial for a high yield.

Some proposals are given for process improvements.
