Non-aqueous solvents for DNP surface enhanced NMR spectroscopy.
A series of non-aqueous solvents combined with the exogenous biradical bTbK are developed for DNP NMR that yield enhancements comparable to the best available water based systems. 1,1,2,2-tetrachloroethane appears to be one of the most promising organic solvents for DNP solid-state NMR. Here this results in a reduction in experimental times by a factor of 1000. These new solvents are demonstrat...
متن کاملPolarographic Reduction of Hydrogen Ion in Non-aqueous Solvents
Sommary-_The polarographic reduction of hydrogen ion, furnished by dissociation of a Brransted acid or present in the undissociated Brsnsted acid, is reviewed for the situation where a solvent other than water is involved. INTRODUCTION THE electrochemical reduction of hydrogen ion in aqueous solution has long been a major problem in electrochemistry, as indicated by the voluminous literature on...
متن کاملCoulometric titration of acids in non-aqueous solvents.
Coulometric titrations of mineral acids, sulphonic acids, carboxylic acids, enols, imides and phenols have been carried out in t-butanol or in acetone with electrically generated tetrabutylammonium hydroxide. Either a potentiometric titration or a visual indicator end-point may be used. The amount of acid titrated ranges from 10 to 60 muequiv, and the precision and accuracy of the method are ex...
متن کاملSurfactants - Surface Active Agents
The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...
متن کاملInteraction and micellar behavior of aqueous mixtures of surface active ionic liquid and cationic surfactant: experimental and theoretical studies
The interaction between an ionic liquid (1-dodecyl-3-methylimidazolium bromide or IL) and cationic surfactant (dodecyltrimethylammonium bromide (DTAB)) in aqueous solution has been investigated at various mole fractions and temperature 30 ˚C using experimental and theoretical methods. The critical micelle concentration (CMC) of pure components and their binary mixtures, mixed micellar compositi...
