The influence of certain hydrophilic materials on the miscibility of phenol and water is examined. The critical solution temperature (C.S.T.) is lowered by sodium stearate and tannin, and raised by colophony, starch, agar and gelatin. For stearate an

The performance of hot-wire thermal conductivity cells has been studied, particular attention being paid to the phenomena of partial and complete reversal of chromatographic peaks. Forced convection has been found to be an important factor in katharo

The gas chromatographic technique of elution by characteristic point (ECP) has been used to determine partition data for HN3 at finite concentrations with tributyl phosphate (TBP) in hydrocarbon (hexadecane) solution in the presence of nitric acid an

Controlled calcination of Texas montmorillonite provides a family of materials differing only in cation exchange capacity (cec). Introduction of alumina pillar precursor ions, followed by calcination at 500°C, then provides a family of pillar densit

Controlled calcination of Texas montmorillonite has allowed production of a range of materials of cation exchange capacity from ≈ 70 mequiv./100 g dry clay to virtually zero. Pillaring of these with Chlorhydrol precursor solution has then provided

Controlled calcination of ion-exchanged Texas montmorillonite leads to layer charge reduction. Detailed chemical analyses of both exchangeable and unexchangeable metal species lead to the conclusion that, in complete contrast to the situation with Wy
