    摘要： The present invention relates to a method for manufacturing calcium zincate crystals that includes at least the following steps: (1) placing calcium hydroxide (Ca(OH)
    2 ) and zinc oxide (ZnO), one of the precursors thereof, or one of the water mixtures thereof in a so-called starting suspension, the mass ratio of water to calcium hydroxide and zinc oxide, or one of the precursors or mixtures thereof, being greater than or equal to 1, preferably from 2 to 15, and in particular from 3 to 5; (2) milling said starting suspension to an ambient temperature less than or equal to 50°C in a wet-phase three-dimensional micro-ball mill for a residence time less than or equal to 15 minutes and in particular from 5 to 25 seconds; (3) recovering a calcium zincate crystal suspension coming out of the mill; and (4) optionally, concentrating or drying said calcium zincate crystal suspension so as to obtain a calcium zincate crystal powder. The invention also relates to the uses associated with the calcium zincate crystals obtained according to the method described above.

    摘要： The invention concerns a method for producing fatty acid alkyl esters and glycerol by implementing a set of transesterification reactions between at least one plant or animal oil and at least one aliphatic monoalcohol comprising the following steps: (A) introducing, into a three-dimensional ball mill, separately or in a mixture, at least one plant and/or animal oil, at least one aliphatic monoalcohol and at least one heterogeneous and/or homogeneous catalyst in order to form an initial mixture; (B) milling said initial mixture at a temperature of less than or equal to 50°C, and preferably of less than or equal to 25°C, in a three-dimensional ball mill, for a holding time of less than or equal to 5 minutes, and preferably of between 5 and 30 seconds and typically of between 5 and 15 seconds; (C) recovering, at the outlet of the three-dimensional mill, a final mixture comprising at least fatty acid alkyl esters, glycerol, the catalyst and the unreacted aliphatic monoalcohol; and (D) separating, from this final mixture, a first phase comprising the fatty acid alkyl esters and a second phase comprising the glycerol, the unreacted aliphatic monoalcohol and the catalyst.
