Per(poly)fluorinated polyoxyethylated carbamates

These materials having the appearance and the consistency of gels are characterized in that they contain a very high proportion of water, of the order of from 60 to 98% weight, and that their structure is a microcellular compartmentalized structure having a very high density of water droplets enclosed in a fine surfactant membrane and contained in a continuous oil/surfactant phase, this structure being impermeable to water and permeable to hydrophobic compounds soluble in fluorocarbons. Use in the field of optics, fillers, cosmetics, pharmacology, lubricants, textiles, photochemistry and electrodynamics.

The invention relates to compounds of the polyfluoroalkyl acetate, thioacetate or acetamide type, which can be denoted by the general formula: ##STR1## in which Rf denotes a perfluoroalkyl radical, m is an integer ranging from 1 to 4, Q denotes an oxygen or sulphur atom or an NH group, X.sup.- denotes an anion, R.sub.1 denotes an alkyl radical containing from 1 to 3 carbon atoms, R.sub.2 denotes the allyl radical or an alkyl radical containing from 1 to 18 carbon atoms, and R.sub.3 denotes an alkyl radical containing from 7 to 18 carbon atoms or one of the following radicals: ##STR2## wherein n is an integer from 2 to 4, R is hydrogen or methyl, and Y denotes C.sub.2 -C.sub.8 alkylene bridge optionally interrupted by an oxygen atom. These compounds can be used as surface-active agents or an monomers for developing artificial vesicles.

The invention relates to non ionic fluorinated compounds having the formula R.sub.F C hd 2H.sub.4 S(R)H, wherein R designates a C.sub.2 H.sub.4 X unit with X=O or S, or a chain exclusively comprising several such units, and two consecutive units can be identical or different, and R.sub.F is a perfluorinated alkyl group exclusive of compounds having the formula:

Novel non ionic fluorinated compounds, their process of preparation and

Novel 2,2-bis(2-perfluoroalkylethylthio)acetaldehydes having the formula: ##STR1## wherein R.sub.F and R'.sub.F are the same or different perfluoroalkyl groups, together with processes for producing the same and using the same to prepare surface active agents and products with hydrophobic and lipophobic properties.

2,2-bis-(2-perfluoroalkylethylthio)-acetaldehydes and process for

New perfluoroalkyl derivatives of benzodiazepine are prepared by reacting an orthophenylenediamine with a beta-diketone at least one of whose alkyls is a C.sub.1 - C.sub.15 perfluoroalkyl. The stable products are useful as heat-exchange substances and as surfactants in organic solution.
