โœฆ Synopsis

A correlation involving solubility parameters to predict the selectivity of a solvent for extractive crystallisation has been developed. It has been found that predicted and observed values of selectivity agree well for extractive crystallisation processes. However, in case of adductive crystallisation processes, it is necessary to use enthalpy changes on mixing as a qualitative criterion, since the correlation does not take into account chemical interactions between solute and the solvent.

We have successfully used cross-linked, partially-hydrolyzed, polyacrylaimide gels to concentrate solutions of high molecular weight solutes. The gels are sizeselective, concentrating solutes whose diameter exceeds 3 nm. They can be easily regenerated by means of pH-induced changes in gel swelling;
