-15. (canceled)
A container with an inner volume of 0.05 to 10000 m3 containing
- a) a liquid comprising a non-substituted saturated aliphatic C6-12 carboxylic acid or a mixture thereof, whereas the liquid has a saturated aliphatic C6-12 carboxylic acid content of 99 to 100 wt.-% and occupies 1 to 99% of the inner volume of the container, and
- b) a gas phase above the liquid,
- wherein
- c) the container is a metallic container comprising walls wherein the walls are solely made of metal or comprise a composite material comprising metal sufficient to prevent infiltration of molecular oxygen through the walls, and
- d) the gas phase above the liquid is an inert gas phase containing nitrogen, helium, neon, argon, krypton, xenon, hydrogen, carbon dioxide, carbon monoxide or a mixture thereof, having a molecular oxygen content of 0 to 100 vol.-ppm.
