The complexation of trifluoroacetic acid with two hexaoxa-“crown” ethers (18/CR/6 and DCC/A) in 1,2-dichloroethane was investigated conductometrically. The equilibrium constants of complex formation are of the same order ...

Viscosities of several uni-univalent electrolytes in hexamethylphosphotriamide (HMPT) at 25°C have been measured. Data were analysed by the Jones–Dole equation, and the B-coefficients discussed on the basis of Einstein's ...

Infrared spectra have been recorded of hexafluoroacetone adsorbed on four samples of rutile which differed in their extents of dehydration by thermal activation or of reduction in hydrogen. Physically adsorbed hexafluoroacetone ...

The slow gas-phase oxidation of ethylal was investigated at low temperatures (160–190°C) by the static method. The main products were carbon oxides, water, acetaldehyde, acetic acid, ethanol and ethyl formate with some ...

Conditions are given for the equilibrium paths followed by cones (axis vertical) in interfaces between two fluids, when raised and lowered by an applied force: using a tensiometer or a rigid (damped) device. Circumstances ...

The interactions between n-propylmercaptan (electron acceptor) and amines (electron donors), such as triethylamine (TEA), N-methylpiperidine (MP), ethyleneimine (EI), N-methylimidazole (MI) and pyridine (PD) are investigated ...

The fluorescence of 1-pyrene sodium sulphonate solubilised in benzene solutions of cetylbenzyl-dimethylammonium chloride/bromide is quenched by the bromide. The quenching constant is not markedly affected by the addition ...

The surface chemistry of Cr2+ and Cr3+ in chromia–alumina catalyst is investigated. Electron spin resonance studies revealed considerable changes in the behaviour of the signals ascribed to Cr3+(at g= 1.986) when exposed ...

Kinetic results for quaternization reactions of four n-alkyl bromides (C2, C3, C4, C6) and benzyl bromide, with poly(4-vinyl pyridine) in sulpholane, at a variety of concentrations and temperatures, have been analysed ...

Heats of immersion in liquid water of Na-Zeolon exchanged with alkali metal, alkaline earth, Ag+, Ti+ and Pb2+ ions are reported. The levels of ion exchange of Zeolon are shown to depend markedly on the degree of hydration ...
