Immobilised lipase B (Candida antarctica lipase B) is, perhaps unexpectedly, catalytically active in liquid ammonia and exhibits chain length selectivity in the ammonolysis of triglycerides. Using glycerol triacetate as the substrate, the ammonolysis

Perfluorinated long chain alkyl amides aggregate in liquid ammonia with increasing concentration which reflects micelle-type formation based on changes in (19)F NMR chemical shifts. The critical micelle concentrations (cmc) decrease with increasing c

Best practice for scale-down of gas–liquid reactions requires control of the volumetric mass transfer coefficient, kLa. It is demonstrated that the use of small bubble columns can provide well-controlled kLa and catalyst dispersion down to a scale

The direct conversion of unactivated esters to the corresponding primary amide is a difficult process. Using methyl benzoate as an example, we have shown that, in liquid ammonia, chromatographic alumina is a useful catalyst for this conversion. The k

The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Bronsted βlg values of −1.18 and −1.34, respectively, when plotted against the

Liquid ammonia is known to be a useful solvent for aromatic nucleophilic substitutions reactions of reactive aromatics. Most of the prior work has been carried out at atmospheric pressure and low temperatures. The purpose of this work is to extend th

The (100), (010) and (001) faces of monoclinic crystals of the organic solid p-chloranil display contrasting reactivities towards hydrolytic dissolution induced by aqueous hydroxide ions. The differing behaviour is rationalised in terms of the functi

A quantitative study of the hydrolytic dissolution of solid p-chloranil at alkaline pH using a combination of the channel flow cell and in situ atomic force microscopy measurements shows that the dissolution is driven by reaction of the substrate wit

The kinetics of the dyeing of a dichlorotriazinyl-reactive dye, Procion Blue MX-R, with knitted cotton fabrics have been studied using a versatile technique based on a spectrochemical channel flow cell. A mechanism is derived where the simultaneous h

The mechanism of the dyeing of cotton and nylon cloth by the azo dyes Orange G and Sunset Yellow FCF was investigated using a channel flow cell. The variation in dyeing with flow rate was found to proceed via a mechanism in which the flux of dye ente
