Abstract:
A liquid coloring suspension for cementitious compositions is provided which contains polycarboxylate dispersant, pigment, and thixotropic additive. The liquid coloring suspension increases the color of cementitious compositions, reduces the water content and has long term stability in that it does not become increasingly viscous over time.
Abstract:
An acquous synfuel composition to be used as an additive for coal and like combustible materials to cause chemical bonding with the coal or materials to transform it into a substance legally defined by United States Air Quality Regulations as a synfuel. The composition contains polyvinyl alcohol, a hydrocarbon wax, and water which interact with the coal or material.
Abstract:
The present invention generally provides a method for increasing the dispersibility of a cationic molecule of interest through the ion exchange of the cationic molecule onto the surface of a substrate having a high surface area. The present invention further provides for the resulting compositions whereby a cationic molecule of interest has been incorporated onto the surface of a high s urface area substrate and where the resulting cation/substrate (such as a cation/organoclay) composition experiences greater dispersibility in a target application system than the cationic molecule of interest alone experiences in that same application system. The method of the present invention further serves to substantially reduce the water solubility of the cationic molecule of interest by incorporating it into a high surface area substrate such as an organoclay. Also, the method of the present invention serves to improve the efficacy of the cationic molecule of interest.
Abstract:
The present invention serves to substantially improve the dust capture property of dedusting oils, by modifying these oils with nonionic and/or cationic surfactants. The application of surfactant modified oils reduces dust that is generated when loose-fill insulation is installed.
Abstract:
The invention relates to the use as surfactant, for the preparation of dispersions of multiphase systems that comprise a continuous aqueous phase containing a high concentration of electrolytes, of hydrophobically modified saccharides of general formula (I) and (II) [A] n (-M) s (I) [B] m (-M) s' (II) wherein[A] n represents a fructan-type saccharide [B] m represents a starch-type saccharide (-M) represents a hydrophobic moiety that substitutes a hydrogen atom of a hydroxyl group of the fructosyl and/or glucosyl units of the fructan-type and starch-type saccharides, which is selected from the group consisting of an alkylcarbamoyl radical of formula R-NH-CO- and an alkylcarbonyl radical of formula R-CO-, wherein R represents a linear or branched, saturated or unsaturated alkyl group with from 4 to 32 carbon atoms, and s and s', which can have the same value or not, represent the number of said hydrophobic moieties that substitute the fructosyl or glucosyl unit, expressed as average degree of substitution (av. DS) which ranges from 0.01 to 0.5. The invention also relates to a method for the preparation and/or stabilisation of dispersions of multiphase systems that comprise a continuous aqueous phase containing a high concentration of electrolytes, by using as surfactant one or more hydrophobically modified saccharides of general formula (I) and/or (II) defined above. Also dispersions of multiphase systems are disclosed that comprise a continuous aqueous phase containing a high concentration of electrolytes and that comprise as surfactant one or more hydrophobically modified saccharides of general formula (I) and/or (II) defined above.
Abstract:
A method of reducing the aggregation and deposition of asphaltene from a fluid containing asphaltene, such as crude oil, which method comprises the addition to the fluid of a compound of formula (I): wherein A is an optionally substituted ring system containing 6 to 14 carbon atoms; n is at least 1 and may equal the number of positions available for substitution in A; each X is independently a linker group; and each R is independently a hydrocarbyl group containing 10 to 25 carbon atoms.
Abstract:
The invention relates to the use of an oil (A) in an aqueous formulation, said oil being defined as: (I) comprising at least one hydrophilic group selected from hydroxyl, ether, amide, ester, carboxylic, phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic functions, and the corresponding salts; (ii) not comprising a cationic group with a pH of 2 - 13, as an aid in depositing an oil (B) dispersion on a surface, said oil being defined as non-ionizable with a pH of 2 - 12 and not comprising any of the aforementioned hydrophilic groups (i).
