Abstract: A method for preparing difluoroacetic acid is described. The method can include: reacting a difluoroacetic acid ester with an aliphatic carboxylic acid which, after transesterification, results in the formation of difluoroacetic acid and the corresponding carboxylic acid ester, the carboxylic acid being selected such that the ester of the carboxylic acid has a lower boiling point than that of difluoroacetic acid; and removing the ester of the carboxylic acid by distillation as the ester forms, thus enabling the difluoroacetic acid to be recovered.

Abstract: The invention relates to a solid formulation containing a liquid composition containing a water-insoluble solid phytosanitary product. The invention especially relates to a solid formulation enabling the formation of nanoparticles of the phytosanitary product during a dispersion in water.

Abstract: The invention relates to the application, in an aqueous formulation, of a mixture comprising at least one solvent and at least one substance having antifoam properties in aqueous medium; the solvent/substance weight ratio is between 99.95/0.05 and 90/10; said solvent is chosen from those for which, in all or part of the range of the abovementioned weight ratio, the mixture is homogeneous, and from those for which the aqueous formulation, comprising from 0.01 50 5% by weight of mixture, is homogeneous.
