摘要： This invention relates to a dispersing agent for use in dispersing a finely divided solid powder in a nonaqueous dispersion medium and a dispersion prepared by using the dispersing agent. The dispersing agent of this invention is a low acid value lanolin fatty acid and/or a salt of the same. By means of this dispersing agent, there can be easily obtained a homogeneous and stable nonaqueous dispersion from which the incorporated solid particles will not separate out or settle even on prolonged standing. Therefore, this dispersing agent can be used advantageously in a broad range of applications such as coatings, dyes, pigments, inks, fuels, lubricating materials and so on.

摘要： The present invention relates to a dispersant for nonaqueous systems which can disperse insoluble fine powders in nonaqueous liquids in a short period of time and give long-term dispersion stability to the resulting dispersions without allowing the formation of the so-called hard cake. The dispersant consists essentially of at least one polyether compound derived from at least one member of the class consisting of polyamine compounds having 5 to 300 active hydrogen atoms per molecule, polyalkylenimine compounds having 5 to 300 active hydrogen atoms per molecule, and derivatives thereof having 5 to 300 active hydrogen atoms per molecule by addition of at least one of ethylene oxide and propylene oxide and at least one alpha-olefin oxide containing 4 to 30 carbon atoms. The polyether compound has a molecular weight of 1,000 to 1,000,000. The dispersant has a favorable constitution resulting from well-balanced and efficient addition of hydrophobic and hydrophilic alkylene oxides and can disperse different fine powders in various nonaqueous liquids in a short period of time. The dispersions obtained show good storage stability for a prolonged period of time. The invention thus greatly contributes to the technical advancement in the field of nonaqueous fine powder dispersions.

摘要： Coarse coal particles are pulverized to at least 70% passing through a standard 200 mesh screen in the presence of water in an amount to form aqueous coal slurries having a coal concentration from 60 to 80% by weight. The pulverization is carried out also in the presence of polyether type polyoxyalkylene adducts having a high molecular weight with polyols having at least three active hydrogen atoms, phenol/aldehyde conden-sates or polyalkyleneimines, or derivatives of these adducts.
