ABSTRACT:
A process for the preparation of a liquifier for mineral binding agents comprising condensing a member of a group consisting of naphthalene sulfonic acid and alkyl naphthalene sulfonic acids with formaldehyde or a formaldehyde precursor in a highly acidic solution until a viscosity of 4,000 to 8,000 mPas is reached, adding water periodically to reduce the viscosity of the mixture until the condensation is complete and neutralizing the mixture to obtain a water-soluble condensation product and the liquifier produced thereby and mineral binding agents containing the same.
