A method of preparing an ester by reacting a carboxylic acid with a (C-C)alcohol in the presence of a catalyst that is suitable for preparing carboxylic acid esters of monomeric carboxylic acids in high yield. The method reduces by-products of the reaction, in particular esters of dimeric, trimeric and/or oligomeric carboxylic acids. The method requires a minimal excess of alcohol and does not require removal of water and/or carboxylic acid ester from the reaction mixture. The method is particularly suitable for the reaction of hydroxyalkylcarboxylic acids and fatty alcohols.

Method of preparing hydroxyalkylcarboxylic acid esters

The present invention relates to a composition containing carbohydrate partial esters, the preparation thereof and products containing the carbohydrate partial esters according to the invention.

Compositions containing carbohydrate partial ester

Suggested are alkoxylation products of 2-isopropyl-5-methyl-hexan-1-ol in which AO stands for an ethylene oxide, propylene oxide or butylenes oxide unit or their mixtures and n denominates an integer of from 1 to 100. 

Biocide compositions comprising alkoxylation products of isoamyl alcohol derivatives

Mixtures of Guerbet alcohols, their use in cosmetic and/or pharmaceutical preparations, and also cosmetic and/or pharmaceutical preparations comprising mixtures of Guerbet alcohols are described. Of suitability as petroleum jelly substitute are in particular Guerbet alcohol mixtures with a melting range, measured by differential scanning calorimetry (DSC), between &#x2212;20&#xb0; C. and +70&#xb0; C., where the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35&#xb1;10&#xb0; C. These are obtainable for example by reacting

Guerbet alcohol mixtures and uses thereof

Described herein are mixed ethers and cosmetic and/or pharmaceutical preparations comprising mixed ethers. Certain mixed ethers have a melting range between &#x2212;25&#xb0; C. and +70&#xb0; C., wherein the width of the melting range comprises at least 30 temperature degrees and the maximum of the melting range is 35 &#xb1;10&#xb0; C. These mixed ethers are obtainable for example by condensation reaction of a) 25 to 90% by weight of unbranched fatty alcohols with a chain length of 12 to 19 carbon atoms; b) 5 to 50 by weight of isostearyl alcohol; c) 0 to 35% by weight of a fatty alcohol with a chain length of 20 and/or 22 carbon atoms; and d) 0 to 25% by weight of a fatty alcohol having 8 and/or 10 carbon atoms.

Mixed ethers and uses thereof

The invention relates to a method for the dimerization of alcohols in the context of a Guerbet reaction, in which one or more alcohols (A) having 2 to 72 C atoms and 1 to 3 OH groups per molecule are reacted in the presence of (a) a base (B), (b) a carbonyl compound (C), and (c) a hydrogenation catalyst (H) from the group of metals ruthenium, rhodium, palladium, osmium, iridium, and platinum, said metals being in the elementary form, with the proviso that the alcohols (A) have at least one primary or secondary OH group, and that a C atom that carries at least one H atom as a substituent is directly adjacent to the C atom with said primary or secondary OH group.
