Abstract

The acetic acid is used for the manufacture of grinding admixtures in the cement industry. The most admixtures used by commercial milling are mixtures of amine acetates, glycols and sugars. The commercial formulations contain 10% acetic acid as amine acetate. In this work the amine acetate was synthesized using the product from fermentation of molasses. In this paper amine acetate was synthesized using the product from acetic fermentation of molasses and it was followed by fermentation of molasses through FT-IR and pH measurement. The fermented product was neutralized with tertiary amine, and finally were adding glycols into the grinding admixture. This admixture was compared with a commercial admixture, having a similar size distribution in both cases.
