    摘要: 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.

    摘要: A double hull ship for the transportation of liquid, high melting aromatic hydrocarbons, such as pitch heated to 200.degree. to 300.degree. C. The tanks are provided with good insulation and with means to introduce inert gas into the tank (1). Heat expansion is allowed for by means of companion expansion joints and sliding bearings (3). Because of the high solidification point of the products, all line systems must be provided with a companion heating system and adequate insulation. A thermal oil system, which simultaneously supplies the emergency heating system (4) of the tank (1), is suitable for this purpose. Separate ballast tanks (17) are installed between the hulls.
