1-Amino-2-propanol → Octanoic acid, compd. with 1-amino-2-propanol (1:1)

Participants

Reaction Steps

10.12 g of octanoic acid, 6.27 g of 1-amino-2-propanol (AMP) and 17 g of water were mixed together to form a solution of AMP-octanoic acid salt (hereafter “FAS2”). The total of FAS2 was then mixed, at room temperature, with 2 000 g in respect to dry mineral matter of a 20 wt. % solids (wet ground at 20 wt % in absence of dispersant) marble of Norwegian origin, in which 75% by weight of the particles had a particle diameter of less than 1 μm, and having a specific surface of 9.2 m2/g. This corresponded to a fatty acid salt addition of 0.82% by dry weight based on the dry weight of calcium carbonate. This product represents a product of according to the invention.
