Title (EN) METHOD FOR PRODUCING ALKOXYLATED POLYPHENOLS
(FR) PROCÉDÉ DE FABRICATION DE POLYPHÉNOLS ALCOXYLÉS
Abstract:
(EN) The invention relates to a method for producing at least one alkoxylated polyphenol, comprising the following consecutive steps: (a) reacting at least one polyphenol, at least one alkoxylating agent and at least one catalyst, in the presence of at least one poly(oxyalkyleneglycol) acting as solvent, at a temperature of 80°C to 200°C, preferably 100°C to 170°C, and a pressure of 0.15 MPa to 2 MPa, preferably 0.2 MPa to 1.8 MPa; and b) removing the residual alkoxylating agent.
(FR) L'invention concerne un procédé de fabrication d'au moins un polyphénol alcoxylé comprenant les étapes successives suivantes : (a) faire réagir au moins un polyphénol, au moins un agent alcoxylant, au moins un catalyseur, en présence d'au moins un poly(oxyalkylèneglycol) en tant que solvant, à une température allant de 80°C à 200°C, de préférence de 100°C à 170°C, sous une pression allant de 0,15 MPa à 2 MPa, de préférence de 0,2 MPa à 1,8 MPa; puis (b) éliminer l'agent alcoxylant résiduel.
