Abstract
L'invention concerne un procédé d'élaboration d'esters fluorés d'acide carboxylique dans lesquels un sel d'un acide carboxylique est mis à réagir avec un halogénure d'alkyle fluoré. Les esters d'acide carboxylique fluorés élaborés selon le procédé de l'invention conviennent particulièrement comme solvants d'électrolytes destinés aux cellules électrochimiques qui demandent un solvant hautement pur, comme c'est le cas pour les piles aux ions lithium.
