To get some insight by conclusions of analogy into the drying process of alcoholic aluminium fluoride sol–gels [AlF 3 /(ROH) x ], the structures of α - and β -AlF 3 ⋅3H 2 O as well as of the nonahydrate AlF 3 ⋅9H 2 O are reinvestigated and di

New aliovalent-doped chromium oxide and fluoride catalysts have been prepared by coprecipitation techniques to obtain solid solutions. The catalysts have been characterized by, e.g., X-ray, BET, and pyridine adsorption analysis, and tested for their

The comparative electrochemical fluorination (ECF) of selected trialkylamines and tetraalkylammonium salts was studied in order to obtain experimental data allowing a precise valuation of the ECF mechanism. The results of the investigation favour the

N , N -Bis (trifluoromethyl) amidosulfonyl fluoride and lower fluorinated analogues can be obtained by electrochemical fluorination as well as by CoF 3 -fluorination of N , N -dimethylamidosulfonyl fluoride or chloride. The CoF 3 process is especiall

The interactions of rat liver microsomal membranes with various emulsified perfluorochemicals (PFCs) have been studied. The percentage of microsomal cytochrome P 450 forming a complex with a PFC decreased with increasing critical solution temperature

The exhalation of perfluorocarbons (PFCs) from the organism after administration of perfluorocarbon-based blood substitutes is discussed in terms of their lipid solubilities, which may be correlated with their critical solution temperatures (CSTs) wi

Tetraalkylated ammonium compounds, which are known to be very stable towards oxidative attack, can be electrofluorinated readily to yield perfluoro tertiary amines. Other than the enhanced formation of gaseous cleavage products, the electrofluorinati

Conventional fluorocarbon emulsions are compared to phospholipid vesicles encapsulating fluorocarbons (PFC's) in cages. Such spherical aggregates behave differently from emulsion droplets. A few outstanding properties such as stability and viscosity

One of the most striking properties of perfluorocarbons is their chemical inertness. Due to this, these compounds are said to be physiobiologically compatible. Therefore, they are suggested for a variety of medical uses including the one as component
