Surfactants with polyether sulfonate structure, which have a propanonylsulfonic acid group as a head group, a process for preparing such surfactants and their use for tertiary mineral oil extraction.

Surfactants with a polyethersulfonate structure method for production thereof and use thereof for tertiary crude oil production

Use of a mixture comprising a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground deposits of hydrocarbons for mobilizing and recovering the hydrocarbons from the underground deposits, the cosurfactant being a substance or a group of substances selected from the following list: 

Surfactant mixtures for tertiary oil recovery

A composition comprising a copper salt of N'-hydroxy-N-cyclohexyldiazenium oxide (CuHDO) and a diluent is useful for combating and/or killing bacteria, mould, yeast and algae in industrial materials and or industrial processes. In a preferred embodiment CuHDO is generated in-situ within the application or medium. The composition may additionally include at least one of certain other biocidal active components.

Microbicidal compositions and their use

Use of water-soluble polymers for tertiary mineral oil production by introducing the polymer into a mineral oil deposit, in which the water-soluble polymers are used in the form of a dispersion of the water-soluble polymer and at least one water-soluble, polymeric stabilizer.

Use of aqueous dispersions for tertiary mineral oil production

Antimicrobial composition comprising iodide and thiocyanate anions, periodic acid, and nitrogen and/or phosphorous containing polymers.

Antimicrobial compositions comprising polymeric stabilizers

The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula IR&#x2014;CO&#x2014;&#x2003;&#x2003;(I)where Ris hydrogen, C&#x2013;C-alkyl, C&#x2013;C-alkenyl or C&#x2013;C-aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NEE, where Eand Emay be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures.

Use of acylated polyamines for the modification of surfaces

The invention relates to the use of grafted polymers as greying inhibitors during the washing and aftertreatment of textile goods. Said polymers are obtained by polymerising A) 10 to 95 wt. % of grafted monomers containing, in relation to A), a) 1 to 99 wt. % of at least one vinyl ester, b) 1 to 99 wt. % of at least one N-vinyl lactam, c) 0 to 90 wt. % of at least one other monoethylenically unsaturated monomer which can be copolymerized with monomers a) and b), and d) 0 to 5 wt. % of at least one monomer having at least two ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of A) 5 to 90 wt. % of at least one polymer B), chosen from polyalkylene oxides containing at least 3 units of a Cto Calkylene oxide, and polytetrahydrofuranes containing at least 3 units of tetramethyl oxide units, and the mixtures thereof.

Use of grafted polyalkylene oxides as greying inhibitors when washing

Use of cationically modified, particulate, hydrophobic polymers, the surface of which has been cationically modified by coating with polyvalent metal ions and/or cationic surfactants, the particle size of which is 10 nm to 100 &#x3bc;m, as additive to rinse compositions, care compositions, detergents and cleaners, and also rinse compositions, care compositions, detergents and cleaners which comprise the cationically modified, particulate, hydrophobic polymers.

Use of cationically modified, particle-shaped, hydrophobic polymers as addition agents in rinsing, care, detergent and cleaning products

The invention relates to the use of cationically-modified, particle-shaped, hydrophobic polymers as addition agents in rinsing, care, detergent, and cleaning products. The surface of said polymers is cationically modified by means of a coating of cationic polymers and the particle size of said polymers ranges from 10 nm to 100 &#x3bc;m.

Use of cationically modified, particle-shaped, hydrophobic polymers as addition agents in textile rinsing or care products and as addition agents in detergents

In a process for the continuous preparation of 2-bromo-2-nitro-1,3-propanediol, nitromethane is firstly reacted with formaldehyde and alkali metal hydroxide and the reaction mixture obtained in this way is subsequently reacted with bromine.
