Abstract: The invention relates to a method for processing (meth)acrylic acid in the presence of at least one stabilising agent. A mixture which contains the stabilising agent and is essentially devoid of (meth)acrylic acid and arising from the processing is introduced into a distilling device, and a low boiling flow which contains the stabilising agent and which is obtained from mixture is reintroduced into the preparation.

Abstract: A device in the form of technical process apparatus or a container with a metallic surface containing iron and/or molybdenum and/or vanadium and/or titanium and/or chromium and/or nickel and/or cobalt, has at least part of the surface treated with a polymeric complex-former (I). An Independent claim is also included for a method for the treatment of metallic surfaces by preparing a clean metallic surface and treating this with (I).
