Perfluoronated cycle-containing tertiary amines used as a basis for gas-conveying emulsions and device for the production thereof

   
   

Tertiary perfluorocycloamines (TPFCAs) of general formula (1) ##STR1## where n=1 or 2, m=2 or 3, X is ##STR2## wherein at n=2 X is ##STR3## as the basis for gas transport emulsions. TPFCAs comprise a group of compounds which are close in their physicochemical properties to perfluoro-N-(4-methylcyclohexyl)-piperidine, particularly in the critical temperature of dissolution in hexane, and which are used in a mixture, forming a number of compounds with gradually varying characteristics. Owing to this, a greater homogeneity of the fluorocarbon phase is achievable in the emulsions and it becomes possible to enhance the stability of the emulsion particles stabilized by an ethylene oxide-propylene oxide block copolymer, with the absence of toxicity for large animals. A mixture of TPFCAs is prepared by electrochemical fluorination of n-piperidinoheptafluorotoluene in anhydrous hydrogen fluoride. The use of this mixture of TPFCAs instead of individual perfluoro-N-(4-methylcyclohexyl) piperidine simplifies, speeds up the process for preparing perfluorinated organic compounds, makes it cheaper, and provides conditions for broader application of gas transport emulsions based thereon.

Perfluorocycloamines tertiary (TPFCAs) do ## geral do ## STR1 da fórmula (1) onde n=1 ou 2, m=2 ou 3, X são ## do ## STR2 wherein em n=2 X são ## do ## STR3 como a base para emulsions do transporte do gás. TPFCAs compreendem um grupo dos compostos que são próximos em suas propriedades physicochemical a perfluoro-N-(4-methylcyclohexyl)-piperidine, particularmente na temperatura crítica da dissolução no hexane, e que são usados em uma mistura, dando forma a um número de compostos com características gradualmente variando. Devido a esta, uma homogeneidade mais grande da fase do fluorocarbon é achievable nos emulsions e torna-se possível realçar a estabilidade das partículas do emulsion estabilizadas por um copolymer do bloco do óxido do óxido-oxide-propylene do etileno, com a ausência do toxicity para animais grandes. Uma mistura de TPFCAs é preparada pelo fluorination eletroquímico do n-piperidinoheptafluorotoluene no fluoreto anhydrous do hidrogênio. O uso desta mistura de TPFCAs em vez do piperidine do indivíduo perfluoro-N-(4-methylcyclohexyl) simplifica, apressa-se acima do processo para preparar compostos orgânicos perfluorinated, faz-se o mais barato, e fornece-se circunstâncias para uma aplicação mais larga dos emulsions do transporte do gás baseados thereon.
