Process for the preparation of substituted dimethyl-(3-aryl-butyl)-amine compounds. The process comprises dehydration by heterogeneous catalysis of substituted 4-dimethylamino-2-aryl-butan-2-ol compounds, to form substituted dimethyl-(3-aryl-but-3-enyl)-amine intermediates, which are then converted by hydrogenation with hydrogen to substituted dimethyl-(3-aryl-butyl)-amine compounds.

The invention relates to novel compositions of matter which may advantageously be used as lubricants or pressure transfer media or else for functional liquids and lubricant additives. The lubricants according to the invention are the reaction products of an electro-philic addition of linear or branched, aliphatic or aromatic carboxylic acids, carboxylic anhydrides, carbonyl halides or novel neoacids to the double bonds of fatty acids, esters thereof and/or of other fatty acid derivatives and also of synthetic esters. Owing to their increased oxidation resistance compared to the starting materials and also their low toxicity, the novel class of synthetic esters based on oleochemicals may find use in novel environmentally compatible lubricants, pressure transfer systems, functional liquids and lubricant additives.

Ionic liquids are immobilized on a functionalized support which carries or contains one component of the ionic liquid, or a precursor to such a component. The ionic liquid may be immobilized via the anion by treating a support with an anion source, e.g., an inorganic halide, before the ionic liquid is applied or formed. Alternatively, the ionic liquid may be immobilized by having the cation covalently bound to the support, e.g., through silyl groups, or incorporated in the support by synthesizing the support in the presence of a suitable base. The immobilized ionic liquids are of use as catalysts, for example, for the Friedel-Crafts reaction, such as alkylation reaction.
