Abstract

La présente invention a pour objet un procédé de préparation de solutions anhydres de phénates alcalins dans des solvants organiques. Ce procédé comprend la synthèse dans un milieu aqueux de phénates alcalins par réaction d'un sulfate alcalin avec de l'hydroxyde de calcium et des phénols, les rapports molaires étant de l'ordre de la stoechiométrie; la filtration du CaSO4 ; la décalcification quantitative de la solution aqueuse résiduelle par addition d'une solution aqueuse d'une base alcaline; la filtration du Ca(OH)2 et des précipités de sulfates alcalins; l'extraction à contre-courant de la solution aqueuse résiduelle avec au moins un solvant organique polaire aprotique; la déshydratation, par distillation de la solution organique, des phénates alcalins obtenus. Elle se rapporte à ces composés.
