CA 2258788

A stable, fluid alkaline earth metal tallate dispersion is prepared by (i) forming a pre-emulsion of fatty acids derived from tall oil, water, and a surfactant; (ii) forming an alkaline earth metal salt dispersion from an alkaline earth metal oxide and/or hydroxide, a lower carboxylic acid, and water; and (iii) incorporating the pre-emulsion into the alkaline earth metal salt dispersion under high shear and low pressure.

On prépare une dispersion stable et fluide de tallate de métal alcalino-terreux: (i) en formant une pré-émulsion d'acides gras dérivés de résines liquides, d'eau et d'un agent tensio-actif; (ii) en formant une dispersion saline de métal alcalino-terreux à partie d'un oxyde et/ou d'un hydroxyde de métal alcalino-terreux, d'un acide carboxylique inférieur et d'eau; et (iii) en incorporant la pré-émulsion à la dispersion saline de métal alcalino-terreux dans des conditions de cisaillement élevé et de faible pression.
