The present invention relates to the use of polyesters which consist of at least one carbohydrate and at least one carboxylic acid, and mixtures thereof, as a hydraulic fluid.

Use of a polyster composition as a hydraulic fluid

The present invention relates to compositions which comprise mixtures of open-chain and cyclic molecules of the sugar alcohols D-sorbitol and D-mannitol which have been esterified with at least one carboxylic acid, processes for preparing these compositions and the use of this composition as lubricant or hydraulic liquid.

Carbohydrate esters for using as lubricants

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.

Compositions of material, especially lubricants and pressure transmitting means, the production and use thereof

A method and a device for the lubrication and for the simultaneous fuel supply of a vegetable oil-rated internal combustion engine is described in which the internal combustion engine is operated exclusively with vegetable oil thereby that during operation an additive-treated vegetable oil is continuously supplied as lubricant and the used vegetable oil lubricant is combusted in doses as engine fuel together with fresh vegetable oil fuel in the engine.

Method and device for lubricating and simultaneously supplying fuel in a vegetable oil-operated combustion engine

A method and a device for the lubrication, and for the simultaneous fuel supply, of an internal combustion engine are described. To an internal combustion engine during its continuous operation an additive-treated vegetable oil is supplied as a lubricant. The used vegetable oil lubricant, together with a mixture of fresh vegetable oil and Diesel oil or rape seed oil methyl ester is combusted in doses in the engine as engine fuel.
