摘要:
The present invention relates to a composition and a method for preparing high-concentration aqueous solutions of betaines or amine oxides which comprise a water-soluble carbohydrate. The high-concentration aqueous solutions of the present invention are pumpable, viscous liquids which are self preserving and remain storage stable for long periods without any bacterial decomposition. The high-concentration aqueous solutions of the present invention are prepared by adding a water-soluble carbohydrate such as cyclodextrins or dextrans to an aqueous solution of the betaine or amine oxide and concentrating the aqueous solution to provide the high-concentration aqueous solution.
摘要:
Acetals are used as a mineral oil substitute, oil component or base oil in invert-emulsion drilling muds, emulsion drilling muds, engine oils, gearbox oils, lubricating oils and also metal-working fluids, coolants, cooling lubricants and hydraulic fluids. As compared with conventional mineral oils, acetals show good biodegradability and are less toxic.

The invention relates to a method for the purification of poly(arylene ethers) of formula (I) in which m=0 to 1.0, n=1.0-m, and Ar1, Ar2, Ar3 and Ar4 independently represent divalent arylene groups. The compound of formula (I) is produced in a first step 1, with a raw product being obtained by bringing a metal or ammonium salt of divalent dihydroxy derivatives of Ar1 or Ar3 into contact with one or more dihalogenated derivatives of Ar2 and/or Ar4, in the presence of a solvent LM1. A precipitate that is present, if appropriate, is separated (step B) so as to obtain a solution L which then undergoes a membrane filtration (step C).
摘要:
Fluorine-containing and two-component compositions exhibit improved surface properties for the permanent oil- and water-repellent surface treatment or modification of mineral and non-mineral substrates for various fields of application. At a simultaneously reduced fluorine content, these compositions have considerably improved application properties and, in combination with suitable stabilizing components and hydrophilic silane components, they exhibit excellent hydrophobic, oleophobic and soil-repellent properties, having overall excellent storage stability.
摘要:
A description is given of an optionally fluorinated polyurethane-polymer hybrid dispersion with enhanced surface properties (low critical surface tensions γc and very high contact angles θ) which is obtainable by a) preparing a dispersion component (binder) based on an aqueous solution or dispersion of an optionally hydroxy- and/or amino-functional polyurethane-polymer hybrid having optionally fluorinated side chains and, if desired, b) subsequently reacting the dispersion component from stage a) with a crosslinker component (D). The polyurethane-polymer hybrid dispersion of the invention can be prepared in solvent-free or low-solvent fashion and with high solids content and requires only a very low level of stabilizing groups.
