Abstract
Official abstract text for this publication.
Use of 2-((1-methylpropyl)amino)ethanol as an additive in an aqueous suspension, containing from 25 to 62 vol. % of at least one calcium carbonate-comprising material, wherein the use provides improved stability with regard to the conductivity of the suspension.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for increasing the pH of an aqueous suspension, containing from 25 to 62 vol. % based on the total volume of the suspension of at least one calcium carbonate-comprising material and having a pH in the range of between 8.5 and 11, comprising adding 2-((1-methylpropyl)amino)ethanol to the suspension in an amount so that the pH of the suspension is increased by at least 0.3 pH units and the conductivity change is not more than 100 μS/cm per pH uni…
