Abstract (en)
[origin: CN105085751A] This invention involves a process for reducing friction in ethanol during its transport through pipelines. This process involves combining ethanol with a polymer-based composition, characterised in that the polymer is obtained from at least 50 mol % of at least one monomer selected from the group comprising N-substituted acrylamides, N-substituted methacrylamides, N,N-substituted acrylamides, N,N-substituted methacrylamides, substituted acrylates and substituted methacrylates.
Abstract (fr)
La présente invention concerne un procédé pour réduire la friction de l'éthanol pendant son transport dans une canalisation. Ce procédé consiste à mettre l'éthanol en contact avec une composition à base de polymère, caractérisé en ce que le polymère est obtenu à partir d'au moins 50 mol% d'au moins un monomère choisi dans le groupe comprenant les acrylamide N-substitués, les méthacrylamide N-substitués, les acrylamide N,N-substitués, les méthacrylamide N,N-substitués, les acrylate substitués, et les méthacrylate substitués.
