Octanoic Acid → Octanoic Acid

Participants

Reaction Steps

10.12 g of octanoic acid and 0.7 g of tetraethylenetriamine (TETA) were mixed together to form TETA-octanoic acid salt/octanoic acid mixture (hereafter “FAS4”). The total of FAS4 was then mixed, at room temperature, with 2 000 g, in respect to dry weight of mineral matter, of a 35 wt. % solids (wet ground at 35 wt % in absence of dispersant) suspension of marble of Norwegian origin, in which 75% by weight of the particles had a particle diameter of less than 1 μm and a specific surface of 9.2 m2/g, at room temperature. This corresponded to a fatty acid/fatty acid salt addition of 0.54% by dry weight based on the dry weight of calcium carbonate. This product represents a product of according to the invention.
