Here we present the mass transfer coefficient for liquid–solid mass transfer to a rotating mesh electrode and a smooth flat disc electrode in a rotor–stator spinning disc reactor. The mass transfer coefficients are measured with the limiting curr

Many drugs and pesticides are presently used as a racemic mixture. However, the biological activity is often concentrated in one of the two enantiomers, the other enantiomer being 50% impurity. A new process has been developed to separate enantiomeri

A method for the determination of the surface tension γ S of cellulosic fibres has been developed. A number of fibres are placed on a liquid surface with a surface tension γ L . The liquid surface tension at which 50% of the fibres float on the sur

In the search for more environmentally friendly processes, the use of micellar structures opens up a range of new possibilities. One of the most exciting applications is the incorporation of homogeneous catalysts in micelles to perform reactions: mic

The chemical synthesis of monoglycerides requires high temperatures, which may lead to the polymerization of unsaturated fatty acids. The enzymatic synthesis of these esters is performed at moderate temperatures and, hence, polymerization is avoided.
