The invention provides a process for the preparation of hydrocarbons substituted with at least one group containing at least one oxygen atom, comprising the process steps

Multi-stage synthesis method with synthesis gas

The invention relates to a method for oxidizing an alkane, comprising contacting the alkane with a type alkB oxidoreductase and using a type alkB oxidoreductase to prepare a mixture of oxidation products of an alkane, wherein the ratio of carboxylic acid to alcohol in the oxidation products is preferably greater than 1:1.

Biological alkane oxidation

A process for the preparation of free carboxylic acids including: A) preparation of carboxylic acid by a biological cell located in an aqueous medium with addition of an amine of formula (I) where R, Rand R, independently of one another, are identical or different, branched or unbranched, optionally substituted hydrocarbon radicals or H; B) for cases where the added amine A) is water-soluble, addition of a water-insoluble amine of formula (I), where, in A) or B), a multiphase system is obtained and the corresponding ammonium carboxylate is formed from the water-insoluble amine and the carboxylic acid; C) removal of the water-insoluble phase; and D) heating of the water-insoluble phase with release of free carboxylic acid.

Method for the production of free carboxylic acids

The invention relates to a method for the enzymatic production of emulsifiers containing mono- and diacylglycerides. In a first step a), a mixture of a phospholipid component and a triacylglyceride component is prepared, then in step b) a quantity of an aqueous solution containing a (phospho)lipase is added to the mixture obtained, to produce a water content of the mixture of between 3 and 15 wt. %. In a subsequent step c), the mixture obtained in the previous step is reacted at a temperature ranging between 20&#xb0; and 80&#xb0; C. over a period of at least two hours and said mixture is then dried.
