Abstract: The present invention concerns a method for the production of carboxylic acid esters containing the steps: a. Supplying of a component containing carboxylic acid and an alcohol; b. Bringing the component containing carboxylic acid in contact with the alcohol in a container for a conversion to carboxylic acid esters by means of esterification or transesterification, characterized in that the container is moved over a distance of at least 1 kilometer during the esterification or the transesterification. The present invention also concerns the use of a ship.
