  • Patent number: 10259719
    Abstract: Process for obtaining lithium compounds and intermediate compounds, comprising the following steps: a) contacting aluminosilicate particles, for example ?-spodumene, with at least one fluorine compound, for example HF, NaF or others; b) stirring the mixture increasing the temperature until reaching an appropriate temperature; c) carrying out at least a precipitation and filtration process of the mixture of step b), and, d) recovering the lithium compound. The process may comprise using HF at a concentration between 5 and 30% v/v or NaF at a concentration between 5 and 30% w/v; a solid/liquid ratio of step a) between 0.9 and 14.4% w/v; a particle size of between 29 and 200 ?m. The final lithium product of the process may be lithium carbonate or lithium fluoride.

  • Patent number: 7803738
    Abstract: Concentrated herbicide formulation, non-volatile, stable at low temperatures and soluble in water of 2,4-D acid ((2,4-dichlorophenoxy) acetic acid), characterized in that it includes: 45 to 75%, w/v of 2,4-D acid, in the form of a water soluble salt of a primary, secondary, or tertiary amine, or a primary, secondary, or tertiary alkanolamine, or a mixture of both; 1 to 40%, w/v of a humectant selected from a group made up of amine oxides, amide amine oxides, ethoxylated fatty amines, glycerin and its derivatives, sorbitol and its derivatives and polyethyleneglycol, and their mixtures; 0.1 to 20%, w/v of an antifreeze selected from a group made up of glycols; 0.01 to 0.5%, w/v of an antifoaming agent chosen from amongst silicon oil emulsions at 10-30%, surfactant agents based on hydrocarbons such as fatty acids and their salts in hydrocarbon, and alcohols with 8 or more carbon atoms, such as 2-ethylhexanol and isooctanol; optionally, 0.5-10%, w/v of a non-polar solvent; and the rest being water.
