The present invention relates to environmentally friendly diesel fuel, containing natural, liquid triglycerides of natural or animal origin, such as rapeseed or soybean oil, and acetals of the formula (I) or (II) ##STR1## in which the substitutents have the meaning defined in the description. This diesel fuel is biodegradable and free of sulfur, nitrogen and aromatics.
摘要:
A nail varnish additive contains a) at least one silane of the general formula wherein the radicals R1, R2, R3, R4 are identical or different, have 1 to 40 carbon atoms and are non-crosslinking, and optionally b) at least one solvent.

The aim of the invention is to improve the stability in storage of bleach activators of the quaternized amino alkyl nitrile type. To this end, the invention provides that a particle containing these bleach activators is enclosed in the most complete possible manner by an enclosing material.
摘要:
Aqueous, alcoholic or aqueous-alcoholic solutions of a monoalkylamine and a reducing sugar are simultaneously injected into a mixing unit and the two solutions are mixed under turbulence in the mixing unit for 6 seconds to 5 minutes at a temperature of 25 to 60° C. and a pressure of 50 to 90 bar. The mixture is then added to a hydrogenation reactor and hydrogenated with hydrogen in the presence of a hydrogenation catalyst. An alkylpolyhydroxyalkylamine is obtained in high yield and with high purity.

Specific ester products obtainable by esterifying a selected polyethylene glycol with a dicarboxylic acid in a molar ratio of 1:0.25 to 1 are described. The novel ester compounds are efficient and easily biodegradable spin finishes.
摘要:
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:
Novel fluorine-containing compositions which have improved surface properties for the permanent oil- and water-repellent surface treatment or modification of mineral and nonmineral substrates for various fields of application and are present in single-component form are claimed. These compositions have, at a reduced fluorine content, significantly improved use properties and they can, in combination with suitable stabilizing components and hydrophilic silane components, be additionally optimized in terms of their hydrophobic, oleophobic and dirt-repellent properties, and they have excellent storage stability.
