Abstract: A process for treatment of shaped bodies comprising copper, wherein an aqueous mixture (M) comprising (a.) chlorine-free acids without carboxyl groups, (b.) oxidizing agents, (c.) aqueous solvent and optionally additional additives is contacted with the shaped body. Another characteristic feature of the process is that the aqueous mixture (M) after the etching or pickling additionally comprises (e.) dissolved copper and is separated from the solid. Also encompassed is a process for workup of the aqueous mixture (M) which has been separated and additionally comprises dissolved copper by electrolysis. Further provided are mixtures (MI) comprising (a.) from 10 to 40% by weight of methanesulfonic acid, (b.) from 10 to 20% by weight of hydrogen peroxide and (c.) from 40 to 80% by weight of water, and the use thereof for etching or pickling of shaped bodies comprising copper.

Abstract: A recurring order management system and method for a computer network is disclosed. The system receives a request to suggest a recurring order for one or more products or services. The system generates a profile which stores the suggested products or services, the suggested recurrence for those products or services and the suggested quantities to deliver upon each recurrence. The order then automatically recurs one or more times according to the specified recurrence.
