Process for producing low-k dielectric films

The invention relates to a method for catalytically oxidizing unsaturated hydrocarbons to form oxidation products, and to the production of saturated alcohols, ketones, aldehydes or carboxylic acids by subsequently hydrogenating the oxidation product. A compound of formula (I) is used as a catalyst during oxidizing in which: R1, R2=H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 signify identical or different radicals or R1 and R2 can be coupled to one another via a covalent bond, with Q1, Q2=the same or different, C, CH, N; X, Z=C, S or CH2; Y=O or OH; k=0, 1 or 2; 1=0, 1 or 2; m=1 to 100 in the presence of a radical initiator. Peroxy compounds or azo compounds can be used as radical initiators. Preferred substrates are cyclic aliphatic or aromatic compounds.

Method for producing saturated alcohols, ketones, aldehydes and carboxylic acids

The invention relates to a catalytically active, permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material can be used for separating mixtures of materials. The fact that various catalytically active substances can be incorporated into the material in various ways makes it highly flexible in terms of possible applications with properties which can be adapted to the particular purpose of an application. The inventive composite material can be used as a catalytically active membrane electrode, for example. According to the invention, the material is obtained by solidifying a suspension on and in a porous, permeable support. The production of the material requires either a very short period of heat treatment at temperatures of around 400&deg; C. or treatment for a longer period at very mild temperatures of below 100&deg; C.

Electrocatalytic selective oxidation of hydrocarbons

The invention relates to a process for preparing hydroxyl-containing aromatic compounds by catalytic oxidation.

Selective oxidation and the synthesis of hydroxyl-containing aromatic

A solid coating composition based on a polyolefin containing a filler is disclosed. The polyolefin is partly or completely reacted with either an unsaturated organic acid or an unsaturated organic acid anhydride.

Solid coating composition for textile floor coverings

Wax-like esterification products derived from optionally partially saponified hard paraffin oxidation products and mono- or multivalent alcohols, which are suitable particularly as lubricants for plastics processing, are formed in the melt with particularly high degrees of esterification and without discolorization. The conversion is conducted at 160.degree. to 220.degree. C. in the presence of zinc salts such as zinc stearate.

Process for the manufacture of wax-like esterification products

A microwax for use in printing ink and varnish systems is obtained by first spraying a wax melt to obtain a powder comprising substantially spherical particles, and subsequently grinding the powder of spherical particles.
